How do I make Java wait for a method to finish before continuing?

Question

So my problem is that I need these methods to run one after another but I cannot work out how to make the methods wait before being run. Any help is appreciated. Thank you. Here

The easiest solution might be to not use threads, but i doubt that is what you want.

What you might be looking for is the concept of locks:

A method may acquire the lock associated with an object by calling:

synchronized(nameOfTheLockObject) {
    //do some code here
}

This acquires the lock of the given Object, executes the code and releases the lock afterwards. If the lock is already acquired by another method/thread, the code pauses until the lock is released by the other method/thread.

You can also add the synchronized statement to methods of a class to make them acquire the lock of the parent object.
