Today I am going to use Java to make a command line application called Simple Interest Calculator with working example. Code was written by my Student Abhijit [doing Bsc (Computer science)].

## Simple Interest Formula

**SI = PRT/100N**

where P= Principle, R=Rate (Annual) ,T= Time Period, N= Frequency of calculation in one year.

## Screen shot

## Simple Interest Java Code :

[java]

import java.util.Scanner;

/*

* By Abhijit Prasad (Student)

* Simple Interest Calculator

*/

class SimpleInterest{

public static void main(String args[]){

double pr, ra;

int t, n;

Scanner inp = new Scanner(System.in);

System.out.println(“Enter the Principle: “);

pr= inp.nextDouble();

System.out.println(“Enter the Rate: “);

ra = inp.nextDouble();

System.out.println(“Enter the Time Period: “);

t=inp.nextInt();

System.out.println(“Enter the Frequency: “);

n=inp.nextInt();

double si=pr*ra*t;

si /= n*100;

System.out.println(“Calculated S.I. “+si);

}

}
