    Default synchronized block

    the general form of synchronized block is
    class table
    {
    .......
    void printTable(int n)
    {
    synchronized(obj)
    {
    ......
    }
    }
    }
    Here obj means object of table class or object of any class.
    1)If we write this in place of obj we get lock on the object of table class.
    That means we canít access the synchronized block simultaneously by same object of table class.
    2) But if write other objectís name other than table class in place of obj,what it means?
    Then which object canít access the synchronized block simultaneously?

    Default Re: synchronized block

    the object that is passed as argument to synchronized block gains access to use that code until it terminates or completes its process.
    It is meant about Thread. One or more thread most often gains access without complete completion of the task. in that case correct result we can't get. So we restricts that unexpected result using synchronized keyword either using at method level or block level where the region is to be processed sequentially.

    Thank you
