Chapter 17.5, Problem 17.17CP

Explanation of Solution

Constraining a type parameter of a generic class with an upper bound:

“Yes”, type parameter of generic class can be constrained with an upper bound using the keyword extends.

Explanation:

The keyword extends is used to restrict the type parameter of generic class.

A type to an upper bound is constrained by the keyword extends.

In order to declare the type parameter with an upper bound, the developer list the name of type parameter, followed by the keyword extends, and followed by its upper bound.

Example:

public class exam<T extends Number> //Line1

{ //Line2

    private T to; //Line3

    private T ra; //Line4

    public exam(T tot, T rank) //Line5

    { //Line6

        to= tot; //Line7

        ra=rank; //Line8

    } //Line9

    public static void main (String[] args) //Line10

    { //Line11

        exam<Integer> e1= new exam<>(2,3); //Line12

        exam<Double> e2= new exam<>(466...

Explanation of Solution

Constraining a type parameter of a generic class with a lower bound:

“Yes”, type parameter of generic class can be constrained with lower bound using the keyword super.

Explanation:

The keyword super is used to restrict the type parameter.

A type to a lower bound is constrained by the keyword super.

In order to declare the type parameter with lower bound, the developer list the name of type parameter, followed by the keyword super, and followed by its lower bound.

Example:

public class exam<T super Integer> //Line1

{ //Line2

    private T to; //Line3

    private T ra; //Line4

    public exam(T tot, T rank) //Line5

    { //Line6

        to= tot; //Line7
