Reading int values using BufferedReader

[Java Tip]

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

 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();
