Java Consider the following class definition for an array-based stack implementation: pubic class Stack { private int[] m_array; private int m_index; public Stack(int cap) { m_array = new int[cap]; m_index = 0; } public void push(int v) { if (m_index == m_array.length)

Consider the following class definition for an array-based stack implementation:
pubic class Stack {
private int[] m_array;
private int m_index;
public Stack(int cap) {
m_array = new int[cap];
m_index = 0;
}
public void push(int v) {
if (m_index == m_array.length)
throw new RuntimeException("push attempted on a full stack");
else {
m_array[m_index] = v;
m_index++;
}
}
}
Follow the steps below to create a class SpecialStack with required instance variables and methods.
a. Make sure that the SpecialStack class inherits from Stack.
b. Declare two private instance variables: a boolean variable m_multiply, and an int variable m_number.
c. Create a constructor that takes three parameters: an int cap, a boolean multiply, and an int number.
d. The constructor should call the constructor of the super class and initialize the instance variables properly.
e. Override the push method so it verifies if m_multiply is true. If so, the method multiplies the parameter v by m_number and then pushes the result onto the stack by calling the push method in the Stack (super) class; otherwise, it pushes v onto the stack without any modification.
