Java Program Help please

MyStack.java

Implement a stack using linked lists data structure. Implement your own linked list. You cannot use Java's java.util.LinkedList.

• pop(): returns and removes the last value on the stack
• push(String item): Push a given value onto the stack
• isEmpty(): returns true or false depending on if the stack is empty
• printStack(): prints the items on the stack to console
• Handles errors for all possible edge cases (i.e. doesnt throw an unhandled exception to the user)
• MyStack(String[] list): constructor which creates the stack with the items in list on the stack. So if list had {a, b, c} the stack would look like: c on top of b on top of a.

MyQueue.java

Implement a queue using the MyStack.java implementation as your data structure. In other words, your instance variable to hold the queue items will be a MyStack class.

• enqueue(String item): inserts item into the queue
• dequeue(): returns and deletes the first element in the queue
• isEmpty(): returns true or false depending on if the queue is empty
• printQueue(): prints the items in the queue to console
• MyQueue(String[] list): constructor which creates the queue with the items in list in the queue: So if list had {a, b, c} the queue would look like: a first, then b, then c.

MyTest.java

• You can have other methods in this class but will be graded to have a:
• Main method which tests every method you implemented above in MyStack and MyQueue.
• As you test the methods, print to console (1) what you are testing, (2) what value you are expecting, (3) whether your test passed or failed.
• Test for edge cases and clearly state in your comment/print out which edge case youre testing.

Console.pdf

• This file has the print out from the main method in MyTest.java
• Also include an answer to the following questions:
• 1) Show an example screenshot of how you used the debugger in fixing your code with a short description on explaining the bug and how you fixed it.
• 2) What is the runtime MyStack's push method, in Big O?
• 3) What is the runtime MyQueue's dequeue method, in Big O?
• 4) What is the space complexity of MyQueue, in Big O?
