While First thread executing in sync block, then second thread will execute all things before the blocks in the method and wait to enter the sync block. Whenever first thread exit from the sync block, then second thread will continue to enter the sync block.

void disNum()// instead of method will take block { synchronized (this) { for(int i=65;i<75;i++) { System.out.println(i); try { Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } for(int j=0;j<5;j++) { System.out.println("Non synchronized-----"); } }

As i have posted Q first thread enter to syn block but 2nd thread should execute that loop which is not part of syn block but its not happening. 2nd thread is waiting how?

the loop is is not before the sync block. Everything before the sync block will execute by 2nd thread. Not after the block.

understoood but as per rule that isn't part of syn block so it should execute parallel.means other thread can continue.
