Simple question about threads

[Krishna Rao]

What is the meaning of

synchronized(someobject){

}

Does it mean only thread is supposed to access someobject's fields and methods ?

[ankush dixit]

it means that if a thread(which has access to someobject's lock) enters synchronized block others threads have to wait...

This means that one one thread at a time can run the statements within the block and the lock of someobject will be acquired before executing the statements and after the execution the lock is released.

Thanks for the replies.

synchronized(a){
....
....
....
}

When the current execution thread has lock over 'a', can any other thread execute in a different path can execute a's method. For ex: a.print() ?

Please clarify

That depends whether print method is syncronized on the same lock or nor .
