Get an input from user scanner class

normally when I get a user interaction from a keyboard I use class scanner to do so but the problem I noticed when using its methods is that it's not handling exception! For example

Scanner input = new scanner();
Int number = input.nextInt();

The above works good for all integer numbers but if the user mistakly entered a character or a string, it will throw an exception and stops executing the rest of the program.

My question is there any way to avoid this?

Thank you in advance.

Try to catch the exception. Or use the hasNextInt method to prevent the exception from being thrown in the first place.

try {
    int number = input.nextInt();
} catch (InputMismatchException e) {
    System.out.println("That wasn't a number!");
}

Perhaps you should catch the exception and ask the user again?

See http://www.functionx.com/java/Lesson14.htm for exactly your problem.
