Question

The following question is based on the following incomplete declaration of the class BoundedIntArray and its constructor definitions.
A BoundedintArray represents an indexed list of integers. In a BoundedIntArray the user can specify a size, in which case the indices range from 0 to size - 1. The user can also specify the lowest index, low, in which case the indices can range from low to low + size - 1.

public class BoundedIntArray
{

private int[] myItems; // storage for the list
private int myLowIndex; // lowest index
public BoundedIntArray(int size)
{

myItems = new int[size];
myLowIndex = 0;
}
public BoundedIntArray(int size, int low)
{
myItems = new int[size];
myLowIndex = low;
}
// other methods not shown
}
Consider the following statements.

BoundedIntArray arrl = new BoundedIntArray(100, 5);
BoundedIntArray arr2 = new BoundedIntArray(100);
Which of the following best describes arrl and arr2 after these statements?

a.
arrl and arr2 both represent lists of integers indexed from 0 to 99.
arrl and arr2 both represent lists of integers indexed from 0 to 99 . ,

b.
arrl and arr2 both represent lists of integers indexed from 5 to 104.
arrl , and, arr2 , , both represent lists of integers indexed from, 5 , to, 104, .,

c.
arrl represents a list of integers indexed from 0 to 104, and arr2 represents a list of integers indexed from 0 to 99.
arrl , represents a list of integers indexed from, 0 , to, 104, , and, arr2 , represents a list of integers indexed from, 0 , to, 99, ., ,

d.
arrl represents a list of integers indexed from 5 to 99, and arr2 represents a list of integers indexed from 0 to 99.
arrl represents a list of integers indexed from 5 to 99 , and arr2 represents a list of integers indexed from 0 to 99 . ,

Answer 1

Answer:

d.

Explanation:

Using the Java code provided, the creation of the BoundedIntArray objects would be that arrl represents a list of integers indexed from 5 to 99, and arr2 represents a list of integers indexed from 0 to 99. This is because arr1 is passing two arguments when it is being created, the first indicates the array size while the second indicates the lowest index. Since it passes two arguments it overrides the constructor and uses the constructor with two parameters. arr2 only passes one argument so it uses the original constructor which automatically sets the lowest index to 0.
