Java 实例Java Examples

In this article, we demonstrate how to compile the HelloWorld.java file. The Java code is as follows:

HelloWorld.java file

public class HelloWorld { public static void main(String []args) { System.out.println("Hello World"); } }

Next, we use the javac command to compile the Java file, and use the java command to execute the compiled file:

c:\jdk\demoapp> javac HelloWorld.java
c:\jdk\demoapp> java HelloWorld

The output of the above code example is:

Hello World
