    Default Converting a String to an Int? Is it possible?

    Hello, Gravity Games here, and I'm working on a world map format for my game in progress. I have already made the format itself, the game reads the file just fine, but my problem is making a header. I need the header to set things that the level data itself can't set, like the maps length/width and the music that plays. Unfortunately, I have a huge problem. Even though the header is just simple numbers (like "27", or "105"), the Strings can't be converted into integers. Is there any way to convert a String to an Int, or some other way around this problem?

    Well, strictly speaking, one doesn't actually convert a String to an int, but you can get an integer value from its String representation:
    public class Whatever
        public static void main(String [] args)
        {
            String string1 = "27";
            String string2 = "105";
            int int1 = Integer.parseInt(string1);
            int int2 = Integer.parseInt(string2);
            int int3 = int1 + int2;
            System.out.println("string1 = " + string1 + ", string2 = " + string2);
            System.out.println("Sum of ints from string1 and string2 = " + int3);
        }
    }

    Output:
    string1 = 27, string2 = 105
    Sum of ints from string1 and string2 = 132


    Reference: Java Integer Class



    Cheers!

    Thanks a lot Zaphod_b! This is just what I needed! Now the map attributes don't have to be hardcoded.
