Jump to level $1$

The while loop reads values from input until an integer is read. Add an exception handler in the while loop to catch an InputMismatchException exception and:

Output "Discarded the invalid cylinder's height entered". End with a newline.

Discard the invalid input.

Click here for example $1($valid input$)$

Click here for example $2($invalid input$)$

Note: Each value read from input is on one line.

import java.util.Scanner;

import java.util. InputMismatchException;
