Arguments come in as an array, which are 0-based.

java myProgram a b c

means

args[0] == 'a'
args[1] == 'b'
args[2] == 'c'

It'd be a String, "like". The class file being run isn't included in the arguments array.

class CommandLine 
{
    public static void main(String args[])
    {
        System.out.println(args[0]);
        System.out.println(args[1]);
    }
}

For Running : java CommandLine aaa bbb

Output -

 aaa
 bbb

Here aaa is treated as first and bbb is treated as second argument for command line.
