Java examples - how to execute compiled Java files

Java Examples

In this paper, we demonstrate how to perform compiled HelloWorld.java file that Java code is as follows:

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

Next we use javac command to compile Java files, after executing the command generates a HelloWorld.class file in the current directory, we can use the java command to execute the compiled file:

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

The output is the above code examples:

Hello World
