复利如何计算频率

Question

所以基本上其他所有东西都起作用，它只是频率部分，必须是每年，每半年，每季度或每月，所有这些都在代码中，我只是不知道如何将它们全部放在计算部分中，以防将来和将来和案例。

package compound;

import java.util.Scanner;

public class Compound {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        double total;
        double rate;
        double amount;
        String optRate = "optRate";
        double fixedRated = 0;
        double time;
        double n = 0;
        String presOrFut = "presOrFut";
        String timed = "timed";
        String freq = "freq";
        double frequency = 0;

        System.out.println("please enter amount: ");
        amount = scanner.nextDouble();

        System.out.println("please enter the rate: ");
        rate = scanner.nextDouble();

        System.out.println("rate of daily, monthly or yearly?");
        optRate = scanner.next();
        switch (optRate) {
            case "daily":
                fixedRated = rate / 365;
            case "monthly":
                fixedRated = rate / 12;
            case "yearly":
                fixedRated = rate / 1;

        }    
        //this is my compounding freq which doesnt work 
        //       System.out.println("please enter the compounding frequency: annualy, Semi-annualy, quartly or monthly");
        //         freq = scanner.next();
        //  switch (freq){
        //     case "annually":
        //        frequency = fixedRated/1;
        //    case "semi":
        //      frequency = fixedRated/2;
        //  case "quartly":
        //        frequency = fixedRated/4;
        //  case "mothly":
        //        frequency = fixedRated/12;

        //  }

        System.out.println("enter the lenght of term: ");
        time = scanner.nextDouble();
        System.out.println("is it daily, monthly or yearly");
        timed = scanner.next();
        switch (timed) {
            case "daily":
                n = time * 365;
            case "monthly":
                n = time * 12;
            case "yearly":
                n = time * 1;
        }
        System.out.println("future value at end of term or present value? ");
        presOrFut = scanner.next();
        switch (presOrFut) {
            case "future":
                total = amount * (Math.pow((1 + fixedRated/100),n));
            case "present":
                total = amount / (Math.pow((1 + fixedRated/100),n));
            System.out.println("your total is :"+ total);

        }

    }
}
