Java Program to calculate Recurring Deposit (RD)

Program:-

public class RecurringDeposit {

 public static void main(String[] args) {
 
  Scanner sc = new Scanner(System.in);
  System.out.println("Enter Principle amount");
  int pa = sc.nextInt();
  System.out.println("Enter rate of interest");
  float ri = sc.nextFloat();
  System.out.println("Enter time duration in quarters like 4 quarters = 1 year");
  int duration = sc.nextInt();
 
  float r = 1+ri/400;
  float m = (float)Math.pow(r, duration)-1;
  float m1 = m*pa;
  float m2 = 1/(float)Math.pow(r,.33);
  float m3 = 1-m2;
 
  float m4 = m1/m3;
  System.out.println("Maturity "+m4);
 }

}
