Saketh's Blog: Program for Simple Interest SQA

public class SimpleInterestTest{

 
    public static void main(String args[]) {
     
        //creating scanner to accept principle, rate and time input form user
        Scanner scanner = new Scanner(System.in);
        System.out.println("Welcome in Java program to calculate Simple interest");
     
        System.err.println("Please enter principle amount :");
        float amount = scanner.nextFloat();
     
        System.err.println("Enter time in years : ");
        float time = scanner.nextFloat();
     
        System.out.println("Enter rate annually : ");
        float rate = scanner.nextFloat();
     
        float interest = simpleInterest(amount, rate, time);
     
        System.out.println("Simple interested calculate by program is : " + interest);
    }
 
    public static float simpleInterest(float principle, float rate, float time){
        float interest = (principle*rate*time)/100;
        return interest;
    }
}

Output:
Welcome in Java program to calculate Simple interest
Please enter principle amount :
1000
Enter time in years :
1
Enter rate annually :
7
Simple interested calculate by program is : 70.0
