Java Scanner exception handling

Question

I would like to receive a Double from the user and handle the exception thrown in case the user didn\'t input a double/int; in that case I\'d like to ask the user to insert

Answer 1

This method keeps on executing the same input token until it finds a line separator i.e. input.nextLine() or input.next()

Check out the following code

private static double inputAmount()
{
    Scanner input = new Scanner(System.in);
    while (true)
    {
        System.out.println("Insert amount:");
        try
        {
            double amount = input.nextDouble();
            return amount;
        } 
        catch (java.util.InputMismatchException e)
        {
            input.nextLine();
        }
    }
}
