Java Breakout game exiting too early
<p>I am taking an intro to programming online. However, I am stuck on one assignment.</p>

<p>The assignment is to write a breakout game. I have successfully written 97% of the game. However, the game stops before all the bricks are removed. Sometimes there are 4 bricks remaining, some times 11. The program is designed to stop when the score counter reaches the point when all the bricks are gone, so it must be reaching that point early.</p>

<p>What am I doing wrong?  </p>

<p><strong>Edit: Inlined code. and rephrased question</strong></p>

<p>I can get the ball to bounce around however the loop escapes before all the bricks have been removed and the ball stops bouncing. The loop is set to escape when the score reaches the point at which all the bricks will be gone. However it's reaching that point too early.</p>
