Given each of the 2 subtyping scenarios below, should the code compile? In other words, would the given subtyping still satisfy a client code that uses the supertype? You should answer “Yes” or “No”, then support your answer (in the context of a client code that uses the supertype).   class A {    public Iterator merge(Iterator itr) throws Exception { … } } class B {    public Iterator merge(Iterator itr)  throws RuntimeException { … } }                                                                 B extends A.   A extends B.  

Consider the code below.   // A typical account has a balance that is a result of summing a sequence of transactions (or amounts) public class Account {               private int balance;               private List amounts;                 // Requires: true               // Effects: Initializes this to have a zero balance and an empty sequence of transactions               public Account() {                              amounts = new ArrayList();                              balance = 0;                              if (repOk() == false) { System.out.println(“Account(): rep-inv violated”); System.exit(-1); }               }               // Requires: true               // Effects: append amount to the sequence of transactions, and add it to balance               public void customerTransaction(int amount) {                              amounts.add(amount);                              balance += amount;                              if (repOk() == false) { System.out.println(“customerTransaction(): rep-inv violated”); System.exit(-1); }               }               public int getBalance() { return balance; }                   // Rep-invariant1:  a) amounts != null               //                               b) balance = sum of all amounts.get(i), where 0 = 0          boolean repOk() {                                                   }                                                                                                      (1 pt) Implement repOk() based on Rep-Invariant1.   (1 pt) Give 2 example values for balance and amounts that do not violate Rep-invariant1. For each example, provide the client code.   (0.5 pt) Give 2 example values for balance and amounts that do violate Rep-invariant1.   (1 pt) Consider an updated Rep-invariant2. Implement repOk() based on it. // Rep-invariant2:   a) amounts != null //                               b) balance = sum of all amounts.get(i), where 0 = 0          //                               d) amounts.get(i) cannot be 0, where 0
