Coding the collision detection and playing sounds

Now that we have done so much theory and preparation, we can finish everything off very quickly. We will write code to detect all the various collisions using the RectF intersects method, play sounds, and call the required methods of our classes.

The bat and the ball

Add the following highlighted code inside the detectCollisions method:

private void detectCollisions(){
     // Has the bat hit the ball?
     if(RectF.intersects(mBat.getRect(), mBall.getRect())) {
          // Realistic-ish bounce
          mBall.batBounce(mBat.getRect());
          mBall.increaseVelocity();
          mScore++;
          mSP.play(mBeepID, 1, 1, 0,...
