Input
The input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line.
Output
For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.

public class Main{
public static void main(String []args){
//这种方式读取数据比较慢。像这题的要求是够了。如果数量超大可使用下面的方法
Scanner sc = new Scanner(System.in);
//下面的这种试读取速度比较快。
//Scanner sc = new Scanner(new BufferedReader(new InputStreamReader(System.in)));
int a,b;
while(sc.hasNextInt()){
a=sc.nextInt();
b=sc.nextInt();
System.out.println(a+b);
}
}
}
像这个题每个OJ上都有示范源代码的呀。
