Here is my solution.It's a method named readInt, other methods are similar.


import java.util.Scanner;

public class StdinReader{

   public static void main(String[] args){

     Scanner scanner = new Scanner(System.in);
     System.out.println(readInt(scanner));
   }

   public static int readInt(Scanner scanner){

     int digit = 0;
     while(true){
       try{
         digit = Integer.parseInt(scanner.next());
         break;
       }catch(Exception e){

       }
     }
     return digit;
   }
}
