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.

## Simple Interest Java Code :

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); } }
