question: public synchronized void insert ( double _priority , Object _data ) { numElements ++ ; if ( numElements == queue . length ) { PriorityQueueNode [ ] tmp = new PriorityQueueNode [ ( int ) ( queue . length * 1.5 ) ] ; System . arraycopy ( queue , 0 , tmp , 0 , queue . length ) ; for ( int i = queue . length ; i < tmp . length ; i ++ ) { tmp [ i ] = new PriorityQueueNode ( ) ; } queue = tmp ; } queue [ numElements ] . data = _data ; queue [ numElements ] . priority = _priority ; reheapify ( numElements ) ; }
target:  Insert the object passed with the priority value passed
