Getting error while reading integer input

Question

Input:

My program:

 public static void main(String args[] ) throws Exception {
        /*
         * Read input from stdin and provide input before running*/

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));


        String line = br.readLine();

        int cases = Integer.parseInt(line);}

Error:

Exception in thread "main" java.lang.NumberFormatException: For input string: "2 "
    at java.lang.NumberFormatException.forInputString(Unknown Source)
    at java.lang.Integer.parseInt(Unknown Source)
    at java.lang.Integer.parseInt(Unknown Source)

How to solve this i want that the value of cases=2; what's wrong

You need to trim your string

int cases = Integer.parseInt(line.trim());}
