Description of program:

Write a program to implement a queue using stack. The file name should be MyQueue.java. Upload the .java file into A1 folder of icollege.

Hint: You can use two stacks and use one as the incoming stack and the other as the outgoing stack. A queue is a FIFO structure, so when we enqueue something, we need to make sure that it does not get popped off before something that was already there. Similarly, when we dequeue something, we have to make sure that elements that were inserted earlier get removed first.
