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. -

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. -

Chapter 9: Java
,ch09.6595 Page 159 Friday, March 25, 2005 2:47 PM Chapter 9 CHAPTER 9 Java Many Java developers like Integrated Development Environments (IDEs) such as Eclipse. Given such well-known alternatives as Java IDEs and Ant, readers could well ask why they should even think of using make on Java projects. This chapter explores the value of make in these situations; in particular, it presents a generalized makefile that can be dropped into just about any Java project with minimal modification and carry out all the standard rebuilding tasks. Using make with Java raises several issues and introduces some opportunities. This is primarily due to three factors: the Java compiler, javac, is extremely fast; the stan- dard Java compiler supports the @filename syntax for reading “command-line param- eters” from a file; and if a Java package is specified, the Java language specifies a path to the .class file. Standard Java compilers are very fast. This is primarily due to the way the import directive works. Similar to a #include in C, this directive is used to allow access to externally defined symbols. However, rather than rereading source code, which then needs to be reparsed and analyzed, Java reads the class files directly. Because the symbols in a class file cannot change during the compilation process, the class files are cached by the compiler. In even medium-sized projects, this means the Java com- piler can avoid rereading, parsing, and analyzing literally millions of lines of code compared with C. A more modest performance improvement is due to the bare mini- mum of optimization performed by most Java compilers. -
Migration-Guide.Pdf
Java Platform, Standard Edition Oracle JDK Migration Guide Release 15 F30923-01 September 2020 Getting Started The purpose of this guide is to help you identify potential issues and give you suggestions on how to proceed as you migrate your existing Java application to JDK 15. The guide also highlights the significant changes and enhancements done in JDK 15. This guide contains the following sections: • Significant Changes in the JDK • Preparing For Migration • Migrating From JDK 8 to Later JDK Releases • Next Steps Note: • Check the Oracle JDK Certified System Configurations for the latest supported platforms and operating system versions. • See Removed APIs, Tools, and Components before you start the migration process. Significant Changes in the JDK Before migrating your application to the latest JDK release, you must understand what the updates and changes are between it and the previous JDK release. If you are migrating from JDK 8, you should also be familiar with the differences between JDK 8 and later releases that are described in Migrating From JDK 8 to Later JDK Releases. See the following sections to learn about some of the significant changes in latest JDK releases. 1 Significant Changes in JDK 15 Release See JDK 15 Release Notes for the complete list of new features and enhancements in JDK 15. The following are some of the updates in Java SE 15 and JDK 15: • Text Blocks, first previewed in Java SE 13, is a permanent feature in this release and can be used without enabling preview features. Text blocks are multiline string literals that avoid the need for most escape sequences, automatically format the string in a predictable way, and give the developer control over the format when desired. -
Java Programming Course Name: Mca – 5Th Semester Course Code: Mca18501cr
University of Kashmir Department of Computer Science JAVA PROGRAMMING COURSE NAME: MCA – 5TH SEMESTER COURSE CODE: MCA18501CR Teacher Incharge: Dr. Shifaa Basharat Contact: [email protected] 1 University of Kashmir Department of Computer Science PACKAGES: Package in Java is a mechanism to encapsulate a group of classes, sub packages and interfaces. Packages are used for: Re-usability: The classes contained in the packages of another program can be easily reused Name Conflicts: Packages help us to uniquely identify a class, for example, we can have two classes with the name Employee in two different packages, company.sales.Employee and company.marketing.Employee. Controlled Access: Offers access protection such as protected classes, default classes and private class. Protected and default have package level access control. A protected member is accessible by classes in the same package and its subclasses. A default member (without any access specifier) is accessible by classes in the same package only. Data Encapsulation: They provide a way to hide classes, preventing other programs from accessing classes that are meant for internal use only Maintenance: With packages, you can organize your project better and easily locate related classes Thus, package is a container of a group of related classes where some of the classes are accessible and are exposed and others are kept for internal purpose. We can reuse existing classes from the packages as many time as we need it in our program. Package names and directory structure are closely related. For example if a package name is college.staff.csc, then there are three directories, college, staff and csc such that csc is present in staff and staff is present college. -
