    Default Reading int values using BufferedReader

    The static method below reads only int values using BufferedReader (stdin) and throws Exception if int is not read.

    Java Code:
     public static int readInt () {
       while (true) {
         try{
           String line = stdin.readLine();
           int value = Integer.parseInt(line);
           return value;
         } catch(java.lang.NumberFormatException e){
           ;
         } catch(IOException e){
           ;
         }
       }
     } // end readInt ()

    Another way is using the Scanner class.

    int value = new Scanner(System.in).nextInt();
