Translate by hand the following class into Java Virtual Machine code (can you improve on the code created by SJC?):

  public class HandTranslate { 
    static int x; 

    ... main method elided ...

    static int testandset(int n)
    {
        int result;
        int i;
        
        if (n > x) x = n;

        i = 0;
        while (i < n)
        {
            result = x * x;
        }
        
        return result;
    }
  }
