键盘输入输出
输入：1 5
10 20
0 0
输出：6
30
代码如下：
import java.io.*;
import java.util.*;
public class Main {
public static void main(String []args)
{
int a,b;
Scanner can=new Scanner(System.in );
System.out.print(" ");
while(can.hasNextInt()){


a=can.nextInt();
b=can.nextInt();
System.out.println(a+b);

}


}
}

问下那个0 0不输出怎么外理

[解决办法]

Java code

public static void main(String []args)  {int a,b;Scanner can=new Scanner(System.in );System.out.print(" ");while(can.hasNextInt()){       a=can.nextInt();   b=can.nextInt();    if(a+b !== 0){        System.out.println(a+b);     }  }
