I recently learned Java and I have a `switch` statement that gets user input *from another class* and i was wondering how to make the `default` `case` for my `switch` statement make the user re-input data.

Currently I have the following basic code

```
static int getMonthInt(String monthName) 
{
    switch(monthName.trim()) 
    {
        case "January":
            return 1;
        case "Febuary":
            return 2;
        case "March":
            return 3;
        case "April":
            return 4;
        case "May":
            return 5;
        case "June":
            return 6;
        case "July":
            return 7;
        case "August":
            return 8;
        case "September":
            return 9;
        case "October":
            return 10;
        case "November":
            return 11;
        case "December":
            return 12;
        default:
            // what do i put here
    }

}

```

I get user input from an input class called from another class like so:

```
public static void main(String[] args) {

    String monthName;
    int dayNumber;
    int yearNumber;

    monthName = Input.getString("Please enter the current month name with a capital letter!");
    dayNumber = Input.getInt("Please enter the current day!");
    yearNumber = Input.getInt("Please enter the current year!"); }

```

This all works. My problem is however that **if someone enters an invalid input such as 'ovtomber' I want the user to be re-prompted to enter data.** Would I put this in the default case of the switch or in the main method (where I get user input) also how would i do this (I tried both ways and couldnt get the expected behavior & I could not find any topics on input validation)?
