Suppose the Following Java Code Was Used to Implement an Abstract

Suppose the following Java code was used to implement an abstract data type for a stack of integers:
class StackOfIntegers implements StackType
{
private int[] StackEntries = new int[20];
private int StackPointer = 0;
public void push(int NewEntry)
{
if (StackPointer < 20)
StackEntries[StackPointer++] = NewEntry;
}
...
A.What would be the value of the variable StackPointer associated with Stack2 after executing the statements
StackType Stack1,Stack2;
Stack1.push(5);
Stack2.push(6);
Stack2.push(7);

B.What would be the value of StackEntries[0] associated with Stack1 after executing the statements in part A?

C.What would be the value of StackEntries[1] associated with Stack2 after executing the statements in part A?

D.What would be the value of StackEntries[0] associated with Stack2 after executing the statements in part A?
