Answer 1

ANSWER

import java.util.Scanner;

public class KboatCompoundInterest

{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

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

double p = in.nextDouble();

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

double r = in.nextDouble();

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

int t = in.nextInt();

double amt = p;

for (int i = 1; i <= t; i++) {

double interest = (amt * r * 1) / 100.0;

amt += interest;

System.out.println("Amount after " + i

+ " year = " + amt);

}

}
