    Default Re: main method

    String args[], which is actually an array of java.lang.String type, and it's name is args here. It's not necessary to name it args always, you can name it strArray or whatever you like, but most programmer prefer to name it args, because that's what everyone else do. When we run a Java program from command prompt, we can pass some input to our Java program. Those inputs are stored in this String args array. For example if we modify our program to print content of String args[] .

    Furthermore, args[] or "arguments" can be used as parameters instructing how a program should run.
