Starting Java

This guide walks you through the entire process of setting up a Java development environment. You will learn how to download and install the Java 2 Standard Edition (JDK) and Eclipse IDE. We will configure the Java Runtime Environment (JRE) by setting the JAVA_HOME variable and adding the PATH. You will also test your Java environment by compiling and running your first application, HelloWorld.java, which prints "Hello, World!" to the console. Start your journey into Java programming with Eclipse effortlessly!
