Threads are synchronized in two ways.

1) block level
2) Method level

Block level synhronization is the better performance
compare to method level.

Block Level:
see the code syntax for block level
synchronized {..
....//code to lock the specific object here..
...}

Method Level:
See the syntax
public void synchronized XXXMethodName(Parameters or
object to acquire locking){.....
...}
