How to handle infinite loop caused by invalid input (InputMismatchException) using Scanner

Question

So, I\'m getting stuck with this piece of code:

import java.util.InputMismatchException;
import java.util.Scanner;

public class ConsoleReader {

    Scanner

package nzt.nazakthul.app;

import java.util.*;

public class NztMainApp {

    public static void main(String[] args) {
    ReadNumber readObj = new ReadNumber();
    readObj.readNumber();
    }

}

class ReadNumber {
int no;

    int readNumber() {
    Scanner number = new Scanner(System.in);
    int no=0;
    boolean b=true;
    do {

        try {
            System.out.print("Enter a number:\t");
            no = number.nextInt();
        } catch (InputMismatchException e) {
            System.out.println("No Number");
            //e.printStackTrace();

            b=false;
        }

    }

    while (b);
    return no;

    }

}

Personally i use BufferedReader and InputStreamReader to read String and check if is a number or not, but with scanner is less code. The code is checked and run ok.
