It is intended to let application developers "write once, run ananywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to rurun on another. Java applications ns are typically compiled to bytecode (class file) that can run on anany Java virtual machine (JVM)) regardless of computer architecture. Java is, as of 2014, one of tthe most popular programming ng languages in use, particularly for client-server web applications, witwith a reported 9 million developers.[10][11] Java was originallyy developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems'Micros Java platform. -

Java Ide's One-On-One*
DR. J VS. THE BIRD: JAVA IDE'S ONE-ON-ONE* Michael Olan Computer Science and Information Systems Richard Stockton College Pomona, NJ 08240 609-652-4587 [email protected] ABSTRACT An important decision facing instructors of introductory programming courses is the choice of supporting software development tools. Usually this involves selecting an integrated development environment (IDE). BlueJ has received widespread adoption for first year courses that use the Java programming language; however, DrJava is emerging as an alternative. This paper features a comparison of the pedagogical approaches used by BlueJ and DrJava as a guideline for selecting the tool best suited to the teaching style used in the introductory course. 1. INTRODUCTION The choice was simple when text editors and the command line were the only tools for developing programs. That changed with the introduction of integrated development environments (IDE's), and campuses nationwide adopted Borland's Turbo Pascal. Languages also have changed. Pascal was designed as a teaching language, but now academic programs use advanced languages designed for professional software engineers. Making these complex languages accessible to beginning students requires a careful selection of the development environment. This discussion will only include Java, currently the dominant language choice for introductory courses. Let us first consider several levels of tool support in the introductory course sequence: 1) Minimal: A text editor and the command line. 2) Simple IDE: Just the basics, no bells and whistles. 3) Professional IDE: Powerful and feature filled. ___________________________________________ * Copyright © 2004 by the Consortium for Computing Sciences in Colleges.

The Impact of Different Teaching Approaches and Languages On
The Impact of Different Teaching Approaches and Languages on Student Learning of Introductory Programming Concepts A Thesis Submitted to the Faculty of Drexel University by Wanda M. Kunkle in partial fulfillment of the requirements for the degree of Doctor of Philosophy September 2010 Copyright 2010 Wanda M. Kunkle. All Rights Reserved. ii DEDICATIONS I dedicate this dissertation to the memory of Nathan J. Kunkle the loving father who encouraged me to become the person I was meant to be and the highly respected educator who inspired me to follow in his footsteps. Nathan J. Kunkle (1907 – 1965) iii ACKNOWLEDGEMENTS I wish to thank my advisor, Robert Allen, and the members of my dissertation committee for their support and guidance in doing the research and writing required to complete this work. I also wish to thank the Computer Science instructors who helped me recruit the students who participated in my research study, as well as the students themselves. Without the students, there would have been no study. I especially wish to thank the friends and family who encouraged me to keep going when I began to falter because I was feeling overwhelmed by the amount of time and effort I needed to put in to complete this dissertation. Some of those friends are on my dissertation committee, so they are getting thanked twice. Finally, a special thanks goes out to my cousin, Durand Kunkle, who regularly called to ask how I was progressing with my dissertation. He has been planning the celebration for some time now. iv TABLE OF CONTENTS LIST OF FIGURES -
Scala for the Impatient
Scala for the Impatient Copyright © Cay S. Horstmann 2012. All Rights Reserved. The evolution of Java and C++ has slowed down considerably, and programmers who are eager to use more modern language features are looking elsewhere. Scala is an attractive choice; in fact, I think it is by far the most attractive choice for programmers who want to move beyond Java or C++. Scala has a concise syntax that is refreshing after the Java boilerplate. It runs on the Java virtual machine, providing access to a huge set of libraries and tools. It embraces the functional programming style without abandoning object-orientation, giving you an incremental learning path to a new paradigm. The Scala interpreter lets you run quick experiments, which makes learning Scala very enjoyable. And, last but not least, Scala is statically typed, enabling the compiler to find errors, so that you don't waste time finding them later in running programs (or worse, don't find them). I wrote this book for impatient readers who want to start programming with Scala right away. I assume you know Java, C#, or C++, and I won't bore you with explaining variables, loops, or classes. I won't exhaustively list all features of the language, I won't lecture you about the superiority of one paradigm over another, and I won't make you suffer through long and contrived examples. Instead, you will get the information that you need in compact chunks that you can read and review as needed. Scala is a big language, but you can use it effectively without knowing all of its details intimately. -
Programming Groovy.Pdf
What readers are saying about Programming Groovy More than a tutorial on the Groovy language, Programming Groovy is an excellent resource for learning the advanced concepts of metaob- ject programming, unit testing with mocks, and DSLs. This is a must- have reference for any developer interested in learning to program dynamically. Joe McTee Developer, JEKLsoft Venkat does a fantastic job of presenting many of the advanced fea- tures of Groovy that make it so powerful. He is able to present those ideas in a way that developers will find very easy to internalize. This book will help Groovy developers take their kung fu to the next level. Great work, Venkat! Jeff Brown Member, the Groovy and Grails development teams At this point in my career, I am really tired of reading books that introduce languages. This volume was a pleasant breath of fresh air, however. Not only has Venkat successfully translated his engaging speaking style into a book, he has struck a good balance between introductory material and those aspects of Groovy that are new and exciting. Java developers will quickly grasp the relevant concepts without feeling like they are being insulted. Readers new to the plat- form will also be comfortable with the arc he presents. Brian Sletten Zepheira, LLC You simply won’t find a more comprehensive resource for getting up to speed on Groovy metaprogramming. Jason Rudolph Author, Getting Started with Grails This book is an important step forward in mastering the language. Venkat takes the reader beyond simple keystrokes and syntax into the deep depths of “why?” Groovy brings a subtle sophistication to the Java platform that you didn’t know was missing. -

Java Programming 2 – Lecture #1 – [email protected]
Java Programming 2 – Lecture #1 – [email protected] About the Java Programming Language Java is an object-oriented, high-level programming language. It is a platform-neutral language, with a ‘write once run anywhere’ philosophy. This is supported by a virtual machine architecture called the Java Virtual Machine (JVM). Java source programs are compiled to JVM bytecode class files, which are converted to native machine code on platform-specific JVM instances. .java source .class JVM executable code files Java bytecode files JVM machine code compiler runtime Java is currently one of the top programming languages, according to most popularity metrics.1 Since its introduction in the late 1990s, it has rapidly grown in importance due to its familiar programming syntax (C-like), good support for modularity, relatively safe features (e.g. garbage collection) and comprehensive library support. Our First Java Program It is traditional to write a ‘hello world’ program as a first step in a new language: /** * a first example program to print Hello world */ public class Hello { public static void main(String [] args) { System.out.println(“Hello world”); } } Contrast with Python Whereas Python programs are concise, Java programs appear verbose in comparison. Python has dynamic typing, but Java uses static typing. Python scripts are generally interpreted from source, whereas Java programs are compiled to bytecode then executed in a high-performance just-in-time native compiler. 1 E.g. see http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html Supporting User Input in Simple Java Programs There are two ways to receive text-based user input in simple programs like our ‘hello world’ example. -
Introduction to Algorithms in Java
Algorithms in Java: Shuffling and Random Numbers Algorithms Introduction Itʹs impossible to study programming – or even talk in depth about it – without talking about algorithms. Theyʹre an essential part of programming. Fortunately, all of us – programmers and non‐programmers alike – have experience with algorithms. Every time you give someone driving directions; every time you use a recipe to cook; every time you follow instructions for using a piece of software – all of these activities (and countless others) involve algorithms. So what is an algorithm? Simply put, an algorithm is a set of instructions, intended to solve a specific problem or accomplish a specific, finite goal, in a direct fashion. What Makes an Effective Algorithm? In general, ambiguity doesnʹt make for a good algorithm; this is particularly true in programming, because computers are mostly incapable of knowing what we want them to do, unless we spell it out precisely. So the algorithms we use should also be precise – even before we translate them into a programming language. An effective algorithm usually has the following characteristics: • Clear conditions of application: What task is the algorithm intended to accomplish, and what are the requirements for us to be able to use it? • Initialization steps & starting conditions: What do we do to prepare our data for the algorithm? How can we tell if weʹre ready to proceed? • Explicit stopping conditions and states: How do we know when weʹre done? How do we know whether we met the desired goal? • Unambiguous steps that lead from the starting conditions to the stopping conditions. Note that “unambiguous” is a subjective term.
