Question

write a program in Java to input principal rate and time calculate and print the simple interest
​

Answer 1

Answer:

import java.util.Scanner;

public class Simple_Interest

{

public static void main(String args[])

{

float p, r, t;

Scanner s = new Scanner(System.in);

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

p = s.nextFloat();

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

r = s.nextFloat();

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

t = s.nextFloat();

float si;

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

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

}

}

Output:-

$ javac Simple_Interest.java $ java Simple_Interest   Enter the Principal : 20202 Enter the Rate of interest : 2.5 Enter the Time period : 3 The Simple Interest is : 1515.15

Answer 2

package Brainly_Answers.Program;

import java.util.Scanner;

public class Simple_Interest {

   public static void main(String[] args) {

       Scanner sc = new Scanner(System.in);

       System.out.println("Enter Principle amount: ");

       double p = sc.nextDouble();

       // p means Principle amount

       System.out.println("Enter Rate of Interest per year: ");

       double r = sc.nextDouble();

       //r means Rate of Interest per year

       System.out.println("Enter Time in years: ");

       double t = sc.nextDouble();

       //t means Time in years

       double si = (p*r*t)/100;

       //si means Simple Interest

       double fa = p+si;

       //fa means Final Amount

       System.out.println("Simple Interest on the principle amount: "+si);

       System.out.println("Final amount after adding the principle to the S.I.: "+fa);

   }
