Write a Java program to accept principal amount, rate of interest, no. of years from the user and display the simple interest.
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();
}
}
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
