What is “String args[]”? parameter in main method Java

Question

I\'m just beginning to write programs in Java. What does the following Java code mean?

public static void main(String[] args)

• What

Answer 1

Those are for command-line arguments in Java.

In other words, if you run

java MyProgram one two

Then args contains:

[ "one", "two" ]

public static void main(String [] args) {
    String one = args[0]; //=="one"
    String two = args[1]; //=="two"
}

The reason for this is to configure your application to run a particular way or provide it with some piece of information it needs.
