Chapter 24.3, Problem 24.3.7CP

Explanation of Solution

Given “get (index)” method:

The following statements will define the “get (index)” method:

//definition of “get” method

public E get (int index)

{

//call the method

checkIndex (index);

//return statement

return data [index];

}

Here, this method calls the “checkIndex (index)” (listing 24.2 in line 59 to 63) to throw an “IndexOutOfBoundsException”, if the index is out of bounds.

Given “add (index, e)” method:

The following statements will define the “add (index, e)” method:

//definition of “add” method

public void add (int index, E e)

{

//call the method

checkIndex (index);

//check the condition

if (index < 0 || index > size)
