eternal loop problem

[sandor]

why is this loop not stopping?

Code:

 public static final int END = Integer.MAX_VALUE;
    public static final int START = END - 100;   
    public static void main(String[] args) {
      int count = 0;
      for (int i = START; i <= END; i++)
        count++;
      System.out.println(count);
    }

All int variables are always less tha or equal to Integer.MAX_VALUE, which is defined as the highest int value. When i gets to Integer.MAX_VALUE andi s incremented, it silently wraps around to Integer.MIN_VALUE, thus the eternal loop.

Hmm.. You are right. Congratulation pegitha, you are careful.

Thanks for that info. There is an awful lot I need to learn.
