Hi Rafael,
I did not program in Java (want to learn it right now), but I think you
should
  * declare num4 _before_ using it
  * pass num4 as argument to putInt

         //Adds num1, num2 and num3 together.
         int num4 = num1 + num2 + num3;

         //puts total
         jTextField4.putInt(num4);
