Answer 2

A program to calculate interest with a parameterized constructor is written as follows:

import java.util.*;

public class interest

{

private int p;     //The declaration of non-static variables

private int n;

private int r;

public interest (int p1, int n1, int r1) //Parameterized constructor to initialize the variables

{

p = p1;

n = n1;

r = r1;

}

int interest() //Method to calculate the interest

{

double si;

si = (p*r*n)/100;

return si;

}

static void main()  //Main function to display the interest

{

interest ob = new interest();

int inte = ob.interest();

System.out.println("The simple interest is: "+inte);

}

}
