Java Simple Interest Program
This program helps you to learn the fundamental structure and syntax of Java programming.
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter principal: ");
double p = sc.nextDouble();
System.out.print("Enter rate of interest: ");
double r = sc.nextDouble();
System.out.print("Enter time (in years): ");
double t = sc.nextDouble();
double si = (p * r * t) / 100.0;
System.out.println("Simple Interest = " + si);
sc.close();
}
}Output
Enter principal: 1000 Enter rate of interest: 5 Enter time (in years): 2 Simple Interest = 100.0
Understanding Simple Interest
Simple interest formula: SI = (P × R × T) / 100.
