	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int total;
		InputStreamReader isr = new InputStreamReader(System.in);
		BufferedReader br = new BufferedReader(isr);
		try {
			System.out.print("Enter number 1: ");
			int n1 = Integer.parseInt(br.readLine());
			System.out.print("Enter number 2: ");
			int n2 = Integer.parseInt(br.readLine());
			total = n1 + n2;
			System.out.println("Total: " + total);
		} catch (NumberFormatException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
