Using the switch statement, write a menu driven program to calculate the maturity amount of a Bank Deposit.
The user is given the following options:

1. Term Deposit
2. Recurring Deposit

For option 1, accept principal (P), rate of interest(r) and time period in years(n). Calculate and output the maturity amount(A) receivable using the formula:

A = P[1 + r / 100]ⁿ

For option 2, accept Monthly Installment (P), rate of interest (r) and time period in months (n). Calculate and output the maturity amount (A) receivable using the formula:

A = P x n + P x (n(n+1) / 2) x r / 100 x 1 / 12

For an incorrect option, an appropriate error message should be displayed.

        Scanner in = new Scanner(System.in);
        System.out.println("Type 1 for Term Deposit");
        System.out.println("Type 2 for Recurring Deposit");
        System.out.print("Enter your choice: ");
        int ch = in.nextInt();
        double p = 0.0, r = 0.0, a = 0.0;
        int n = 0;

        switch (ch) {
            case 1:
            System.out.print("Enter Principal: ");
            p = in.nextDouble();
            System.out.print("Enter Interest Rate: ");
            r = in.nextDouble();
            System.out.print("Enter time in years: ");
            n = in.nextInt();
            a = p * Math.pow(1 + r / 100, n);
            System.out.println("Maturity amount = " + a);
            break;

            case 2:
            System.out.print("Enter Monthly Installment: ");
            p = in.nextDouble();
            System.out.print("Enter Interest Rate: ");
            r = in.nextDouble();
            System.out.print("Enter time in months: ");
            n = in.nextInt();
            a = p * n + p * ((n * (n + 1)) / 2) * (r / 100) * (1 / 12.0);
            System.out.println("Maturity amount = " + a);
            break;

            default:
            System.out.println("Invalid choice");
        }
    }
}

Output:

Type 1 for Term Deposit
Type 2 for Recurring Deposit
Enter your choice: 1
Enter Principal: 10000
Enter Interest Rate: 4
Enter time in years: 3
Maturity amount = 11248.640000000001
