In the previous method insert, the second ifstatement tests the value of newPosition. Should the boolean expression it tests be isEmpty() || (newPosition == 1)? Explain.
What will be an ideal response?
Although you could test for an empty list, such a test is not necessary. When a list is empty, itemCount is zero. The only acceptable position for an insertion is 1, because the boolean expression (newPosition >= 1)&& (newPosition <= itemCount + 1) will be true. Therefore, the body of the first ifstatement will execute, and the insertion into the empty list will occur correctly.
