Quick Java Question

[EpsiIon]

I'm writing a short Java program for a computer science class that has to be done under a certain size and with a limited number of semi-colons. I've already met the requirements but I'm trying to make my program even more efficient.

Right now I'm looking for a way to traverse an array with only a String and the array. Any variables I declare would not be in the same scope as the traversal, so I can't do that. I can't think of any possible way to do this and could use your help if you can think of a short solution to this problem.

Thanks,
Epsilon

what do you have to do while traversing the array ?
just print the value ?

if thats the case .... you could just use the String to store the index and traverse while you System.out the values ?

does that help ?

Integer.valueOf() can parse a String representing a number.

I seriously doubt you could re-use an existing String variable to do array traversal more concisely than you can with the for loop construct (and a dedicated integer index). Although you might save a semicolon, obviously it would be less efficient from a time/space standpoint.

And Strings are immutable to boot, so using a String over an int (not an Integer) is less efficient.
