GetName () + "put an element");}, "Thread 1") .start (); new Thread (()-> {q.remove () System.out.println (Thread.currentThread (). GetName () + "take an element"); q.remove (); System.out.println (Thread.currentThread (). GetName () + "take an element"); q.remove (); System.out.println (Thread.currentThread ().
