Mehran Sahami Handout #18 CS 106A October 12, 2007 Variables, variables, everywhere… Based on a handout by Patrick Young. Local Variables Local variables are created local to the method (or the block—see “Block Scope” section below) in which they are defined. They are destroyed when execution of the method has been completed. Local variables can only be accessed from within the method in which they are declared. Because of their transient nature, local variables cannot store persistent information about an object between method calls. Local Variables Example Consider, for example, the following snippet of code. class AnExample extends ConsoleProgram { public void methodOne { int a = readInt("Enter a: "); println("a = " + a); } public void methodTwo { int b = a; // BUG!: cannot refer to variable a in methodOne println("b = " + b); } } The variables a and b are local variables declared within different methods in the class AnExample . Because these variables are local variables, a can only be referred to within methodOne and variable b can only be accessed within methodTwo . Our attempt to initialize b using the value of a is illegal, as code in methodTwo cannot access local variables from methodOne or any other method. Because local variable values do not persist after their containing method has completed, the variable a will be destroyed when methodOne has completed execution. The next time methodOne is called, a new variable a will be created. Block Scope While we typically think of local variables as local to a particular method, in Java local variables are actually local to a block of code. While a method defines a block of code (since the opening and closing braces of the method define a block), for and while loops, if -statements, and other constructs are also considered blocks of code. -

Serial Verb Constructions Revisited: a Case Study from Koro
Serial Verb Constructions Revisited: A Case Study from Koro By Jessica Cleary-Kemp A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Linguistics in the Graduate Division of the University of California, Berkeley Committee in charge: Associate Professor Lev D. Michael, Chair Assistant Professor Peter S. Jenks Professor William F. Hanks Summer 2015 © Copyright by Jessica Cleary-Kemp All Rights Reserved Abstract Serial Verb Constructions Revisited: A Case Study from Koro by Jessica Cleary-Kemp Doctor of Philosophy in Linguistics University of California, Berkeley Associate Professor Lev D. Michael, Chair In this dissertation a methodology for identifying and analyzing serial verb constructions (SVCs) is developed, and its application is exemplified through an analysis of SVCs in Koro, an Oceanic language of Papua New Guinea. SVCs involve two main verbs that form a single predicate and share at least one of their arguments. In addition, they have shared values for tense, aspect, and mood, and they denote a single event. The unique syntactic and semantic properties of SVCs present a number of theoretical challenges, and thus they have invited great interest from syntacticians and typologists alike. But characterizing the nature of SVCs and making generalizations about the typology of serializing languages has proven difficult. There is still debate about both the surface properties of SVCs and their underlying syntactic structure. The current work addresses some of these issues by approaching serialization from two angles: the typological and the language-specific. On the typological front, it refines the definition of ‘SVC’ and develops a principled set of cross-linguistically applicable diagnostics. -
Java Static Keyword
This page was exported from - TechnicalStack Export date: Sun Sep 26 13:56:23 2021 / +0000 GMT Java static keyword Java static keyword The static keyword in java is used for memory management mainly. We can apply java static keyword with variables, methods, blocks and nested class. The static keyword belongs to the class than instance of the class. The static can be: - variable (also known as class variable) - method (also known as class method) - block - nested class 1) Java static variable If you declare any variable as static, it is known static variable. - The static variable can be used to refer the common property of all objects (that is not unique for each object) e.g. company name of employees,college name of students etc. - The static variable gets memory only once in class area at the time of class loading. Advantage of static variable It makes your program memory efficient (i.e it saves memory). Understanding problem without static variable class Student{ int rollno; String name; String college="ITS"; } Suppose there are 500 students in my college, now all instance data members will get memory each time when object is created.All student have its unique rollno and name so instance data member is good.Here, college refers to the common property of all objects.If we make it static,this field will get memory only once. Java static property is shared to all objects. Example of static variable //Program of static variable class Student8{ int rollno; String name; static String college ="ITS"; Student8(int r,String n){ -
CS 61A A&S Section 3.0 Object-Oriented Programming
CS 61A A&S Section 3.0 Object-Oriented Programming | Above the line view This document should be read before Section 3.1 of the text. A second document, \Object-Oriented Programming | Below the line view," should be read after Section 3.1 and perhaps after Section 3.2; the idea is that you first learn how to use the object-oriented programming facility, then you learn how it's implemented. Object-oriented programming is a metaphor. It expresses the idea of several independent agents inside the computer, instead of a single process manipulating various data. For example, the next programming project is an adventure game, in which several people, places, and things interact. We want to be able to say things like \Ask Fred to pick up the potstickers." (Fred is a person object, and the potstickers are a thing object.) Programmers who use the object metaphor have a special vocabulary to describe the components of an object-oriented programming (OOP) system. In the example just above, \Fred" is called an instance and the general category \person" is called a class. Programming languages that support OOP let the programmer talk directly in this vocabulary; for example, every OOP language has a “define class" command in some form. For this course, we have provided an extension to Scheme that supports OOP in the style of other OOP languages. Later we shall see how these new features are implemented using Scheme capabilities that you already understand. OOP is not magic; it's a way of thinking and speaking about the structure of a program. -
Declaring Data Member Public C
Declaring Data Member Public C Rickard brooch stickily. Interceptive and hamulate Connie enure, but Norbert crossways extinguishes her patroness. Is Mario estimated or electrotonic when strangulating some moribundity deified deeply? Optimize for declaring data member public If dynamic allocation is necessary, prefer to keep ownership with the code that allocated it. This process of creating an object from a class is known as instantiation. Here is the quite surprising output of the program. Data attributes need not be declared; like local variables, they spring into existence when they are first assigned to. The term __________ means the ability to takemany forms. In many cases, this is not a problem, but it is a problem in some cases. Use rvalue references only in certain special cases listed below. By default, functions and data members of the class are public. How many data members should be in every class and why? Is it acceptable to omit default constructors in a class? For accessing the data, the declaration of a friend function should be done inside the body of a class starting with the keyword friend. The constructor is declared much like a normal member function but it will share the name of the class and it has no return value. Spirit would be impossible without it. The basic idea is really very simple. Giving sensible names to types and variables is much better than using obscure names that you must then explain through comments. Special member functions called constructors and destructors. This makes it impossible for the class to ensure that invariant properties of that variable are respected. -
Two Types of Serial Verb Constructions in Korean: Subject-Sharing and Index-Sharing
Two Types of Serial Verb Constructions in Korean: Subject-Sharing and Index-Sharing Juwon Lee The University of Texas at Austin Proceedings of the 21st International Conference on Head-Driven Phrase Structure Grammar University at Buffalo Stefan Muller¨ (Editor) 2014 CSLI Publications pages 135–155 http://csli-publications.stanford.edu/HPSG/2014 Lee, Juwon. 2014. Two Types of Serial Verb Constructions in Korean: Subject- Sharing and Index-Sharing. In Muller,¨ Stefan (Ed.), Proceedings of the 21st In- ternational Conference on Head-Driven Phrase Structure Grammar, University at Buffalo, 135–155. Stanford, CA: CSLI Publications. Abstract In this paper I present an account for the lexical passive Serial Verb Constructions (SVCs) in Korean. Regarding the issue of how the arguments of an SVC are realized, I propose two hypotheses: i) Korean SVCs are broadly classified into two types, subject-sharing SVCs where the subject is structure-shared by the verbs and index- sharing SVCs where only indices of semantic arguments are structure-shared by the verbs, and ii) a semantic argument sharing is a general requirement of SVCs in Korean. I also argue that an argument composition analysis can accommodate such the new data as the lexical passive SVCs in a simple manner compared to other alternative derivational analyses. 1. Introduction* Serial verb construction (SVC) is a structure consisting of more than two component verbs but denotes what is conceptualized as a single event, and it is an important part of the study of complex predicates. A central issue of SVC is how the arguments of the component verbs of an SVC are realized in a sentence. -

10. Classes: an Initial Example
10. Classes: An Initial Example This is the first chapter about classes. It is also the first chapter in the first lecture about classes. Our basic coverage of classes runs until Chapter 13. 10.1. The Die Class Lecture 3 - slide 2 In this section we encounter a number of important OOP ideas, observations, and principles. We will very briefly preview many of these in a concrete way in the context of a simple initial class. Later we will discuss the ideas in depth. We use the example of a die , which is the singular form of "dice", see Program 10.1. One of the teaching assistants in 2006 argued that the class Die is a sad beginning of the story about classes. Well, it is maybe right. I think, however, that the concept of a die is a good initial example. So we will go for it! On purpose, we are concerned with use of either the singular or the plural forms of class names. The singular form is used when we wish to describe and program a single phenomenon/thing/object. The plural form is most often used for collections, to which we can add or delete (singular) objects. Notice that we can make multiple instances of a class, such as the Die class. In this way we can create a number of dice. The class Die in Program 10.1 is programmed in C#. We program a die such that each given die has a fixed maximum number of eyes, determined by the constant maxNumberOfEyes . The class encapsulates the instance variables : numberOfEyes , randomNumberSupplier , and the constant maxNumberOfEyes . -
Corpus Study of Tense, Aspect, and Modality in Diglossic Speech in Cairene Arabic
CORPUS STUDY OF TENSE, ASPECT, AND MODALITY IN DIGLOSSIC SPEECH IN CAIRENE ARABIC BY OLA AHMED MOSHREF DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Linguistics in the Graduate College of the University of Illinois at Urbana-Champaign, 2012 Urbana, Illinois Doctoral Committee: Professor Elabbas Benmamoun, Chair Professor Eyamba Bokamba Professor Rakesh M. Bhatt Assistant Professor Marina Terkourafi ABSTRACT Morpho-syntactic features of Modern Standard Arabic mix intricately with those of Egyptian Colloquial Arabic in ordinary speech. I study the lexical, phonological and syntactic features of verb phrase morphemes and constituents in different tenses, aspects, moods. A corpus of over 3000 phrases was collected from religious, political/economic and sports interviews on four Egyptian satellite TV channels. The computational analysis of the data shows that systematic and content morphemes from both varieties of Arabic combine in principled ways. Syntactic considerations play a critical role with regard to the frequency and direction of code-switching between the negative marker, subject, or complement on one hand and the verb on the other. Morph-syntactic constraints regulate different types of discourse but more formal topics may exhibit more mixing between Colloquial aspect or future markers and Standard verbs. ii To the One Arab Dream that will come true inshaa’ Allah! عربية أنا.. أميت دمها خري الدماء.. كما يقول أيب الشاعر العراقي: بدر شاكر السياب Arab I am.. My nation’s blood is the finest.. As my father says Iraqi Poet: Badr Shaker Elsayyab iii ACKNOWLEDGMENTS I’m sincerely thankful to my advisor Prof. Elabbas Benmamoun, who during the six years of my study at UIUC was always kind, caring and supportive on the personal and academic levels. -
1 Noun Classes and Classifiers, Semantics of Alexandra Y
1 Noun classes and classifiers, semantics of Alexandra Y. Aikhenvald Research Centre for Linguistic Typology, La Trobe University, Melbourne Abstract Almost all languages have some grammatical means for the linguistic categorization of noun referents. Noun categorization devices range from the lexical numeral classifiers of South-East Asia to the highly grammaticalized noun classes and genders in African and Indo-European languages. Further noun categorization devices include noun classifiers, classifiers in possessive constructions, verbal classifiers, and two rare types: locative and deictic classifiers. Classifiers and noun classes provide a unique insight into how the world is categorized through language in terms of universal semantic parameters involving humanness, animacy, sex, shape, form, consistency, orientation in space, and the functional properties of referents. ABBREVIATIONS: ABS - absolutive; CL - classifier; ERG - ergative; FEM - feminine; LOC – locative; MASC - masculine; SG – singular 2 KEY WORDS: noun classes, genders, classifiers, possessive constructions, shape, form, function, social status, metaphorical extension 3 Almost all languages have some grammatical means for the linguistic categorization of nouns and nominals. The continuum of noun categorization devices covers a range of devices from the lexical numeral classifiers of South-East Asia to the highly grammaticalized gender agreement classes of Indo-European languages. They have a similar semantic basis, and one can develop from the other. They provide a unique insight into how people categorize the world through their language in terms of universal semantic parameters involving humanness, animacy, sex, shape, form, consistency, and functional properties. Noun categorization devices are morphemes which occur in surface structures under specifiable conditions, and denote some salient perceived or imputed characteristics of the entity to which an associated noun refers (Allan 1977: 285). -
