August 24, Content series: This content is part of in the series: Introduction to Java programming, Part 1 http: This content is part of the series: Introduction to Java programming, Part 1 Stay tuned for additional content in this series.

Find out what to expect from this tutorial and how to get the most out of it. About this tutorial The two-part Introduction to Java programming tutorial is meant for software developers who are new to Java technology. Work through both parts to get up and running with object-oriented programming OOP and real-world application development using the Java language and platform.

This first part is a step-by-step introduction to OOP using the Java language. After you're introduced to your development environment's components, you begin learning basic Java syntax hands-on.

Programming examples in Part 2 build on the Person object that you begin developing in Part 1. Objectives When you finish Part 1, you'll be familiar with basic Java language syntax and able to write simple Java programs.

Follow up with " Introduction to Java programming, Part 2: Constructs for real-world applications " to build on this foundation. Prerequisites This tutorial is for software developers who are not yet experienced with Java code or the Java platform.

The tutorial includes an overview of OOP concepts. System requirements To complete the exercises in this tutorial, you will install and set up a development environment consisting of: The recommended system configuration is: At least MB of disk space to install the software components and examples.

Java platform overview Java technology is used to develop applications for a wide range of environments, from consumer devices to heterogeneous enterprise systems.

In this section, get a high-level view of the Java platform and its components. By default, you see three panes in the Javadoc.

The top-left pane shows all of the packages in the API, and the bottom-left pane shows the classes in each package. The main pane to the right shows details for the currently selected package or class. For example, if you click the java. Like any programming language, the Java language has its own structure, syntax rules, and programming paradigm.

The Java language's programming paradigm is based on the concept of OOP, which the language's features support. The Java language is a C-language derivative, so its syntax rules look much like C's.

Structurally, the Java language starts with packages. A package is the Java language's namespace mechanism. Within packages are classes, and within classes are methods, variables, constants, and more. You learn about the parts of the Java language in this tutorial.

The Java compiler When you program for the Java platform, you write source code in. The compiler checks your code against the language's syntax rules, then writes out bytecode in.

Bytecode is a set of instructions targeted to run on a Java virtual machine JVM.

In adding this level of abstraction, the Java compiler differs from other language compilers, which write out instructions suitable for the CPU chipset the program will run on. The difference is that the JVM is a piece of software written specifically for a particular platform.

The JVM is the heart of the Java language's "write-once, run-anywhere" principle. Your code can run on any chipset for which a suitable JVM implementation is available. JVMs are available for major platforms like Linux and Windows, and subsets of the Java language have been implemented in JVMs for mobile phones and hobbyist chips.

The garbage collector Rather than forcing you to keep up with memory allocation or use a third-party library to do sothe Java platform provides memory management out of the box.

When your Java application creates an object instance at runtime, the JVM automatically allocates memory space for that object from the heap— a pool of memory set aside for your program to use. The Java garbage collector runs in the background, keeping track of which objects the application no longer needs and reclaiming memory from them.Free C & C++ Compilers and IDE's; Anjuta: Free open-source IDE for C and C++ on Linux/GTK/GNOME.

Java is defined by a specification and consists of a programming language, a compiler, core libraries and a runtime (Java virtual machine) The Java runtime allows software developers to write program code in other languages than the Java programming language which still runs on the Java virtual machine.
