• In this lab, we will develop an array implementation of stacks.
• Download the provided code.
• Unpack the code into a new Eclipse Java project.
• The code includes the following files:
  • numstack package
    • StackViewer.java: Run this program to get an interactive view of your stack.
  • numstack.model package
    • ArrayIntStack.java: This is the only file you will modify for this assignment. You will use an array of integers to implement a stack.
      • If you use ArrayList you will receive no credit for the assignment.
    • IntStack.java: This is a general interface for a stack of integers. You will want to call popNotEmpty() and peekInRange() at the right places, to ensure the appropriate methods fail when necessary.
    • IntStackTest.java: These are the unit tests for your stack. Your grade depends on passing these tests.
    • ArrayIntStackTest.java: Run this file to see the results of the unit tests for your ArrayIntStack implementation.
