You can use the synchronized keyword to specify that a given method (or
even a given block of code inside a method) can be the only block running
in that object at any given time. That should do what you want.
Adding the the synchronized modifier to a method locks out all other
synchronized methods on that object for its duration, but the
"synchronized(obj) {}" form for synchronizing just a block of code lets
you explicitly control what you are synchronizing on for finer grain
control.
