Java synchronized Keyword

The synchronized keyword is a modifier that locks a method so that only one thread can use it at a time. This prevents problems that arise from race conditions between threads.

In the example above, removing the synchronized keyword from the transfer() method may cause the values of a and b to be modified by another thread in between operations. This would result in the total amount between the two variables to change.
