I've made a program that takes arguments from the command prompt. I use the args as conditions for if statements. Now I want to give from 2 to 4 arguments. The problem is that my array gives an Arrayindexoutofboundsexception if I want to give for example only 2 arguments since my if statements contain conditions for args[2] and args[3] aswell.

args.length will tell you the number of arguments.
Remember that args is a totally standard java array
of Strings.
