Suppose the Following Java Code Was Used to Implement an Abstract

Short Answer

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 Stack after executing the statement
StackType Stack;

B.Then,what would be the value of StackPointer associated with Stack after executing the statement
Stack.push(5);
