Dead easy, just put the '!' before your condition. For example:

Code:

public class TestApp 
{
    public static void main(String[] args)
    {
        int count = 0;
        System.out.println("Starting program");
        String testString1 = "hello";
        String testString2 = "world";
        
        while(!testString1.equals(testString2) && count != 2000)
        {
            count++;
            System.out.println("Number "+count+" This means it is not equal");
            
        }
    }

}

The count is there just to stop the infinite while loop that killed my computer!
