import java.util.Scanner;
public class P1001 {
    int a,b;
    public void jf() {
        Scanner in=new Scanner(System.in);
        a=in.nextInt();
        b=in.nextInt();
        System.out.println(a+b);
    }
    public static void main(String[] args) {
        P1001 TheP1001=new P1001();
        TheP1001.jf();
    }
}

@Entity909 类应该取名Main的吧

@Entity909 第二行的 P1001 要改为 Main

洛谷要求主类名必须为 Main。
