Explanation / Answer

The code is compiled using "javac <filename>.java".
The bytecode file is generated, which is then run using "java <filename> argument1 argument2 argument3........"
The argument is missing while the code is being run, that is the reason it gives an ArrayIndexOutOfBoundException.
The argument is not provided and at line 30, an argument at index 0 is asked for.

Run the code as: java Int ArrayTest 39
