It sounds like you're asking how to create a critical section of code. In Java, that's very easy. Just use the key word "synchronized". It's typically used to synchronize an entire method, by you can also synchronize a block of code if you want.

There can be 2 ways of doing this. Either make the method synchronized by using the keyword 'synchronized' or use the synchronized statement that allows u a finer granularity of locking.
