Java

Example

Adding two numbers. Numbers will be space separated on a single line.

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println(sc.nextInt() + sc.nextInt());
    }
}

Note

On problems with larger inputs, Scanner may be too slow. In such cases, we recommend using BufferedReader and StringTokenizer instead. For example:

import java.io.*;
import java.util.*;

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        StringTokenizer st = new StringTokenizer(br.readLine());
        System.out.println(Integer.parseInt(st.nextToken()) + Integer.parseInt(st.nextToken()));
    }
}
