what is synchronized? 1

[tkforever]

I am looking at sample code and the project basically uses ServerSockets for a simple BankAccount thing. The commands that the client will use are deposit withdraw and getBalance. These methods have:

public synchronized void deposit(double amount)

Can anyone please explain to me what synchronized does? Is it for the threads?

thanks

A synchronized method means that only one thread can run it at a time. Other threads are locked out to protect resources from interference by multiple access at one time.
