Thread.sleep () with java sync

Question

when calling Thread.sleep (10000) current Thread will go into sleep state. If Thread.sleep (10000) is called in the synchronization method, can another thread execute during this period?

Answer 1

If you are executing Thread.sleep(10000)as part of a synchronized method or block not , release the lock. Therefore, if other threads are waiting for this lock, they will not be able to execute.

If you want to wait a certain amount of time for a condition to occur and release an object lock, you need to use Object.wait(long)

Answer 2

private synchronized void deduct()
{
    System.out.println(Thread.currentThread().getName()+ " Before Deduction "+balance);
    if(Thread.currentThread().getName().equals("First") && balance>=50)
    {
        System.out.println(Thread.currentThread().getName()+ " Have Sufficent balance will sleep now "+balance);
        try
        {
            Thread.currentThread().sleep(100);
        }
        catch(Exception e)
        {
            System.out.println("ThreadInterrupted");
        }
        balance =  balance - 50;
    }
    else if(Thread.currentThread().getName().equals("Second") && balance>=100)
    {
        balance = balance - 100;
    }
        System.out.println(Thread.currentThread().getName()+ " After Deduction "+balance);
    System.out.println(Thread.currentThread().getName()+ " "+balance);
}
