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:

Code java:

---

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:

Code :

---

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

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