Java - Language Given the following definition of the class One:

class One {

private int x, y;

public A(int x, int y) { this.x = x; this.y = y;}

public A() {this.a = 1; this.b = 1;}

public int f( int a) {return a*x*y;}

}

provide the definition of the class B that is derived from class A such that it would have:

a private integer data member called z.

a constructor that would take three integers parameters called x, y and z. The first two parameters are to be used to initialize the base class data members and the third parameter is to be used to initialize z.

a default constructor that would use the previous constructor to set all data members to 1.

an overridden version of the function f that would return a*x*y*z using the base class version of the function.

an overloaded version of f that would take two integers parameters called mand n and would return a*x*y*z*m*n.
