S

The parameters which are provided to the program at the command line.

Eg:d:\>java a 10 20 30


Here,“java” is an interpreter, “a” is  filename,10,20,30 are arguments passed to the program while executing the program


And the notation of String args[] in main method will be cleared with the command line arguments.
public static void main(String[] args)


The “String[]args” declares args as an array of strings. Args by default holds the strings given to the program while executing it.


class CommandMadeEasy

{

public static void main(String args[])

{

System.out.println(args[0]);//holds the first string

System.out.println(args[1]);//holds the second string

System.out.println(args[2]);//holds the third string

} }
