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
}
Which of the following is the best reason for declaring the data fields myItems and myLowIndex to be private rather than public?
This permits BoundedIntArray objects to be initialized and modified.
Answer A: This permits, BoundedIntArray , objects to be initialized and modified.
Answer B: This permits, BoundedIntArray , methods to be written and tested before code that uses a, , BoundedIntArray , is written.
Answer C: , This helps to prevent clients of the, BoundedIntArray , class from writing code that would need to be modified if the implementation of , BoundedIntArray , were changed.,
Answer D: This prevents compile-time errors whenever public methods are called that access the private data fields.
.
Answer E: This prevents run-time errors whenever public methods are called that access the private data fields.
