Learning Java by Building Android Games

Decisions in Java

We can now summon enough of Java prowess to ask a question but a real math game must obviously do much more than this. We need to capture the player's answer, and we are nearly there with that—we can detect button presses. From there, we need to be able to decide whether their answer is right or wrong.
