Java Examples - How to execute compiled Java files
Java ExamplesIn this article, we demonstrate how to execute the compiled 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. After running this command, a HelloWorld.class file will be generated 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 of the above code example is:
