How to fix (int) = Integer.parseInt(String) crashing if a word is used instead of a number

I have

(String) = console.readLine("_____"); (int) = Integer.parseInt(String);

If instead of a number I type a word into my console, I get a bunch of errors. How can I instead cause the console to just ask for an actual number instead of crashing?

According to the Java 8 documentation, a NumberFormatException is thrown if the input is not a valid integer. Surround the code involving parseInt with a try-catch block involving NumberFormatException.
