Learn how to setup Java and run your Java program before beginning with understanding the first Java program.
Create a new file StudyopediaDemo and save it as StudyopediaDemo.java, since java program has .java extension. The name of the file should match the class name, So, the class name in our program is StudyopediaDemo.
public static void main(String arg)
