Answer 2

Answer:

import java.util.Scanner;

public class Interest

{

private int p;

private float r;

private int t;

private double interest;

private double amt;

public void input() {

Scanner in = new Scanner(System.in);

System.out.print("Enter principal: ");

p = in.nextInt();

System.out.print("Enter time: ");

t = in.nextInt();

}

public void cal() {

if (t == 1)

r = 6.5f;

else if (t == 2)

r = 7.5f;

else if (t == 3)

r = 8.5f;

else

r = 9.5f;

interest = (p * r * t) / 100.0;

amt = p + interest;

}

public void display() {

System.out.println("Principal: " + p);

System.out.println("Interest: " + interest);

System.out.println("Amount Payable: " + amt);

}

public static void main(String args[]) {

Interest obj = new Interest();

obj.input();

obj.cal();

obj.display();

}

}
