2. Code

import java.util.Scanner; //调用Java的Scanner类，用于获取控制台的输入
public  class Main
{
    
    
    public static void main(String[] args)  //程序的入口
    {
    
    
        int a,b;
        Scanner scan=new Scanner(System.in);
        a=scan.nextInt(); //nextInt() 是取next() 然后把字符串解析成一个int数字
        b=scan.nextInt();
        System.out.println(a+b);
        scan.close();
    }
