QUESTION 27

QUESTION 27 

A programmer must create a generic class MinMax and the type parameter of MinMax must implement Comparable. 
Which implementation of MinMax will compile? 
 
A. class MinMax<E extends Comparable<E>> {     E min = null;     E max = null;
     public MinMax() {}     public void put(E value) { /* store min or max */ } 
B. class MinMax<E implements Comparable<E>> {     E min = null;     E max = null;
     public MinMax() {}     public void put(E value) { /* store min or max */ } 
C. class MinMax<E extends Comparable<E>> {     <E> E min = null;
     <E> E max = null;     public MinMax() {}     public <E> void put(E value) { /* store min or max */ } 
D. class MinMax<E implements Comparable<E>> {     <E> E min = null;
     <E> E max = null;     public MinMax() {}     public <E> void put(E value) { /* store min or max */ }  
Solution : A
