Question

write a program in java to find and print the simple interest and amount. given , principal = Rs.5000,rate=4%, time = 4 years ?​

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);

}

}

Write a Java program to calculate Simple Interest/**

*

* Java program to calculate Simple Interest in Java.

* Input to program is principle, rate and time and output is simple interest

* @author

*/

public class SimpleInterestTest{

public static void main(String args[]) {

//creating scanner to accept principle, rate and time input form user

Scanner scanner = new Scanner(System.in);

System.out.println("Welcome in Java program to calculate Simple interest");

System.err.println("Please enter principle amount :");

float amount = scanner.nextFloat();

System.err.println("Enter time in years : ");

float time = scanner.nextFloat();

System.out.println("Enter rate annually : ");

float rate = scanner.nextFloat();

float interest = simpleInterest(amount, rate, time);

System.out.println("Simple interested calculate by program is : " + interest);

}

public static float simpleInterest(float principle, float rate, float time){

float interest = (principle*rate*time)/100;

return interest;

}

}

Output:

Welcome in Java program to calculate Simple interest

Please enter principle amount :

1000

Enter time in years :

1

Enter rate annually :

7

Simple interested calculate by program is : 70.0
