(Solved) : Dozen Stack Stack Fixed Size 12 Elements Dozen Stack Full Element Stack Longest Removed Ma Q26505737 . . . .

A dozen stack is a stack with a fixed size of 12 elements. If a dozen stack is full, then the element that has been on the stack, the longest, is removed to make room for a new new element. For this problem, you are required to design a class named DozenStack.java, which extends DozenStackAbstract.java, and implements push method to captures this specification of a dozen stack.

given : DozenStackAbstract.java

public abstract class DozenStackAbstract{

   private Character[] c;
   private int total;
   public DozenStackAbstract(){
      c=new Character[12];
      total=0;
   }
   public abstract void push(char c);
   public boolean isEmpty(){
      return total==0;
   }
   public boolean isFull(){
      return total==12;
