Well I can think of one way. It involves some complex amounts of math (parabola). So i'm going to provide a very simple answer.

int y = 0;

and in the method that tests for the spacebar...

if (y !< 1){
    if (y < 30){

   y += 1;

   }

   if (y > 30){

    y -= 1;


    }
}

I haven't tested it out yet, but it should work in theory....But it won't animate anything, this code is only going to take the sprites Y value and make it go up. That's just about the easiest jumping method that can exist....
