As discussed in this section, instead of having our queue methods throw exceptions in the case of "erroneous" invocations, we could have the queue methods handle the - boolean safeEnqueue (T element) adds element to the rear of the queue; returns true if element successfully added, false otherwise - T safeDequeue ( ) returns nu11 if this queue is empty; otherwise removes front element from this queue and returns it a. Add these operations to the ArrayBoundedQueue class. Create a test driver application to demonstrate that the added code works correctly. b. Add these operations to the LinkedQueue class. Create a test driver application to demonstrate that the added code works correctly
