Question

write a java program to find the difference between simple(SI) and compound interest (CI) when principal rate and time are given :specifications are:
class name
Difference
Instance value SI, CI, amt, diff, p, r, t​

Answer 1

Answer:

import java.util.Scanner;

public class JavaExample

{

public static void main(String args[])

{

float p, r, t, sinterest;

Scanner scan = new Scanner(System.in);

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

p = scan.nextFloat();

System.out.print("Enter the Rate of interest : ");

r = scan.nextFloat();

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

t = scan.nextFloat();

scan.close();

sinterest = (p * r * t) / 100;

System.out.print("Simple Interest is: " +sinterest);

}

}

Answer 2

import java.util.*;

public class Difference

{

public static void main (String args[])

{

Scanner in = new Scanner(System.in);

int p , r , t ;

double si, ci , d;

System.out.println("Enter the values of principal, rate and time :");

p = in.nextInt();

r = in.nextInt();

t = in.nextInt();

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

System.out.println("Simple Interest =" +si);

ci = Math.pow(p(1+r/100),t);

System.out.println("Compound Interest =" +ci);

d = (si - ci);

System.out.println("Difference between simple interest and the compound interest is =" +d);

}
