Is my code for fix withdrawl correct?

import java.util.*;
	public class save
	{
	public static void main(String args[]) 
		{
		double Money = 0, principle_amount, Interest_rate = 0, Amount, n;
		int Time = 0, Actual_amount_need;
		Scanner sc = new Scanner(System.in);
		System.out.println("Enter desired cashflow: ");
		System.out.println("Enter time (in months): ");
		System.out.println("Enter rate: ");
		Money = sc.nextDouble();
		Time = sc.nextInt();
		Interest_rate = sc.nextDouble();
		try 
			{
			if (Money > 0 && Time > 0 && Interest_rate >= 0)
				{
				if (Interest_rate != 0) 
					{
					Interest_rate = Interest_rate / 100;
					principle_amount = Money * ((1 - Math.pow((1+(Interest_rate/12)),(-Time)))/(Interest_rate / 12));
					} 
				else 
					{
					Amount = Money * Time;
					principle_amount = Amount;
					}
				Actual_amount_need = (int)(principle_amount + 0.5);
				System.out.println("Money to be deposited now: " + Actual_amount_need);
				return;
				} 
				else 
				{
				System.out.println("Error");
				}
			}
			catch (Exception e) 
			{
			System.out.println(e);
			System.out.println("not Amount valid input");
			}
		}
	}
