Consider the following two approaches for implementing a Stack class and discuss the advantages and disadvantages for each of the two techniques: 1. Inheritance based stack Implementation The Stack is implemented by extending Java Collection Framework (JCF) class ArrayList: public class Stack extends ArrayList { // ... stack implementation goes here } 2. Composition based stack Implementation The Stack is implemented by defining a JCF ArrayList object as instance variable of the class Stack: public class Stack { private ArrayList stk = new ArrayList (); // ... the rest of the stack implementation goes here } Be sure to cite sources (if any)
