Hi, and welcome to the Ranch!

When posting code, if you UseCodeTags(←click), it will be easier to read, which will make it easier for people to help you. I've added the code tags to your original post.

As for your question, if you read the docs for that exception, it explains what causes it. I'm pretty sure it's also covered in the docs for wait(), notify(), and notifyAll(). In short, you can only call X.wait(), X.notify(), or X.notifyAll() if you're inside a synchronized (X) { ... } block, or an equivalent synchronized method. If you're getting that exception, it's because you're calling one of those methods on a object you're not synchronized on.
