This is an interactive Java program which accept Input from User using

**java.util.Scanner**class. By the way calSI() method is used to calculate the simple interest. The formula to calculate Simple Interest is given below:`simple_interest = (total_amount * rate * no_of_years) / 100`

**PROGRAM**import java.lang.*; // Import Language package import java.util.*; // Import Utility package to accept data class SimpleInterest { int amount; // data member declaration float rate; float years; double SI; SimpleInterest(int a, float r, float y) // Constructor to initialize data members { amount = a; rate = r; years = y; } void calSI() // method to calculate simple interest { SI = (amount*rate*years)/100; System.out.println("Simple Interest = "+SI); } public static void main(String args[]) { Scanner s = new Scanner(System.in); System.out.print("Enter Principal Amount :: "); int amt = s.nextInt(); // Converting string to int System.out.print("Enter Rate of Interest :: "); float rt = s.nextFloat(); System.out.print("Enter No. of years :: "); float yrs = s.nextFloat(); SimpleInterest e = new SimpleInterest(amt,rt,yrs); e.calSI(); } }

**OUTPUT**C:\>javac SimpleInterest.java C:\>java SimpleInterest Enter Principal Amount :: 3000 Enter Rate of Interest :: 5 Enter No. of years :: 4 Simple Interest = 600.0
