    IITM GROUP OF INSTITUTIONS, MURTHAL SONIPAT DEPARTMENT: COMPUTER SCIENCE AND ENGG. SUBJECT: ADVANCE JAVA CSE-306B UNIT : 1 JAVA LANGUAGE BASICS JAVA: Java is a general-purpose, concurrent, object-oriented, class-based, and the runtime environment(JRE) which consists of JVM which is the cornerstone of the Java platform. This blog on What is Java will clear all your doubts about why to learn java, features and how it works. In this What is Java blog, I would be covering following topics: What is Java used for? History of Java What is Java? Features of Java Components in Java What is Java used for? Before I answer the question, what is Java used for, let me brief you about why you should choose Java. Java is highly popular and has dominated this field from early 2000‘s till the present 2018. Java has been used in different domains. Some of them are listed below: Banking: To deal with transaction management. Retail: Billing applications that you see in a store/restaurant are completely written in Java. Information Technology: Java is designed to solve implementation dependencies. Android: Applications are either written in Java or use Java API. Financial services: It is used in server-side applications. Stock market: To write algorithms as to which company they should invest in. Big Data: Hadoop MapReduce framework is written using Java. Scientific and Research Community: To deal with huge amount of data. Wait! Java can do more. 1 Let‘s see how some of the technologies make use of Java as an essential core of their functionalities.

  • Programming in Java Unit-I an Overview Of
    PROGRAMMING IN JAVA UNIT-I AN OVERVIEW OF JAVA: James Gosling, Patrick Naughton, Chris Worth, ED Frank and Mike Sheridan conceived Java at Sun Microsystems, Inc in 1991. It took 18 months to develop the first Working version. This language was initially called ‘OAK’ but was renamed “JAVA” in 1995. The primary motivation was the need for a platform-independent (i.e. architecture- neutral) language that could be used to create software to be embedded in various consumer electronic devices such as microwave oven and remote controls. As you can probably guess, many different types of CPU’s are used as controllers. The trouble with C and C++ (and most other languages) is that they are designed to be compiled for a specific target. Although it is possible to compile a C++ program for just about any type of CPU, to do so requires a full C++ compiler together for that CPU. The problems are that compilers are expensive and time consuming to create. An easier- more cost efficient solution was needed. In an attempt to find such a solution, Gosling and others began work on a portable, platform-independent language that could be used to produce code that would run on a variety of CPU’s under different environments. This effort ultimately led to the creation of Java. In 1993, the World Wide Web (WWW) appeared on the Internet and transformed the text-based Internet into a graphical rich environment. The project team came up with the idea of developing web applets (tiny programs) using the new language that could run on all types of computers connected to the Internet.

    History of Java The history of Java is very interesting. Java was originally designed for interactive television, but it was too advanced technology for the digital cable television industry at the time. The history of java starts with Green Team. Java team members (also known as Green Team), initiated this project to develop a language for digital devices such as set-top boxes, televisions, etc. However, it was suited for internet programming. Later, Java technology was incorporated by Netscape. The principles for creating Java programming were "Simple, Robust, Portable, Platform-independent, Secured, High Performance, Multithreaded, Architecture Neutral, Object-Oriented, Interpreted and Dynamic". Currently, Java is used in internet programming, mobile devices, games, e-business solutions, etc. There are given the significant points that describe the history of Java. 1) James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991. The small team of sun engineers called Green Team. 2) Originally designed for small, embedded systems in electronic appliances like set-top boxes. 3) Firstly, it was called "Greentalk" by James Gosling, and file extension was .gt. 4) After that, it was called Oak and was developed as a part of the Green project. Why Java named "Oak"? 5) Why Oak? Oak is a symbol of strength and chosen as a national tree of many countries like U.S.A., France, Germany, Romania, etc. 6) In 1995, Oak was renamed as "Java" because it was already a trademark by Oak Technologies. Why Java Programming named "Java"? 7) Why had they chosen java name for java language? The team gathered to choose a new name.

  • Handout 13 Introduction to Object-Oriented Programming in Python
    Handout 13 CS602 – Data-Driven Development with –Fall’20 Page 1 of 5 Handout 13 Introduction to Object-Oriented Programming in Python • Object-oriented programming (OOP) involves programming using objects. • An object represents an entity important for an application; similar objects share the same structure (data/properties/variables) and behavior (functions/methods) • Objects are defined using Class definitions. The concept of ‘Class’ is synonymous with ‘type’. • Each object is an instance of a class. Instance variables are tied to specific objects. Each object has its own instance variables. • In addition, there are class variables, associated with the class and shared by all objects of that class. A Python class uses variables to store data fields and defines methods to perform actions. Additionally, a class provides a special type method, __init__(), known as initializer, which is invoked to initialize the data components of a newly created object. An initializer can perform any action, but initializer is designed to perform initializing actions, such as creating the instance variables (a.k.a. data fields) of an object. EXAMPLE Let’s create a class definition for object type Review. Each review should have a numeric rating, a maximum possible rating and review text. Since these values are going to be different for different Review objects, they define properties of each individual object, thus are called instance variables rating, maxrating and reviewText '''Version 1 of the Review class; includes the __init__ method. Demonstrates instance variables and parameter 'self' - the obligatory reference to the calling object.''' class Review: # Method __init__ is called automatically during class instantiation (a.k.a.

  • Dissertation Submitted to the Graduate Faculty of Auburn University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy
    Repatterning: Improving the Reliability of Android Applications with an Adaptation of Refactoring by Bradley Christian Dennis A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 2, 2014 Keywords:Refactoring, Code Smells, Patterns, Non-functional Requirements, Verification Copyright 2014 by Bradley Christian Dennis Committee: David Umphress, Chair, Associate Professor of Computer Science and Software Engineering James Cross, Professor of Computer Science and Software Engineering Dean Hendrix, Associate Professor of Computer Science and Software Engineering Jeffrey Overbey, Assistant Research Professor of Computer Science and Software Engineering Abstract Studies of Android applications show that NullPointerException, OutofMemoryError, and BadTokenException account for a majority of errors observed in the real world. The technical debt being born by Android developers from these systemic errors appears to be due to insufficient, or erroneous, guidance, practices, or tools. This dissertation proposes a re- engineering adaptation of refactoring, called repatterning, and pays down some of this debt. We investigated 323 Android applications for code smells, corrective patterns, or enhancement patterns related to the three exceptions. I then applied the discovered patterns to the locations suggested by the code smells in fifteen randomly selected applications. I measured the before and after reliability of the applications and observed a statistically significant improvement in reliability for two of the three exceptions. I found repatterning had a positive effect on the reliability of Android applications. This research demonstrates how refactoring can be generalized and used as a model to affect non-functional qualities other than the restructuring related attributes of maintainability and adaptability.
