Which command-line arguments should be passed to the program to produce the following output?

Arg is 2 -

A java MyFile 1 3 2 2
B java MyFile 2 2 2
C java MyFile 1 2 2 3 4
D java MyFile 0 1 2 3

Explanation

Java passes arguments after the class name to main as elements of the String[] args array. Because array indexing is zero-based, args[3] is the fourth supplied argument. java MyFile 1 3 2 2 therefore assigns 2 to arg3 and prints Arg is 2.
