How to check type matching in Java?

Question

Java

In the example below, if a non-numeric value is entered on request or an empty string, the parser swears and the program crashes.
How to make a loop to check the condition of the entered number, if a value different from the number is entered, then the request is repeated until the number is entered?

System.out.println("Введите число и нажмите <ENTER>");
            String fNumb = reader.readLine();
            int fInumb = Integer.parseInt(fNumb);
