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 Java coding sample 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.To understand a programming language you must practice the programs, this way you can learn the language faster.

Converting Between Strings (Unicode) and Other Character Set Encodings. Java is different in that it does not compile the code directly into machine language code. Compilation creates bytecode out of the source code.

The heart of the Java platform is the concept of a "virtual machine" that executes Java bytecode programs. A GUI—Graphical User Interface—of an application built using Java is made up of layers of containers.

The first layer is the window used to move the application around the screen of your computer. It is a top-level container that gives all other containers and graphical components a place to.
