注：

此题就是利用Long.parseLong()和Long.toHexString（）的

replaceAll("\\+","")，是去除其中的‘+’，因为进制计算不支持带“+”的某一进制的数字字符串，‘-’可以，同时还需要判断正数负数，从而利用Long.toHexString（）。

Java代码：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner inScanner = new Scanner(System.in);
        while(inScanner.hasNext()) {
            long l = Long.parseLong(inScanner.next().replaceAll("\\+", ""),16)
                    + Long.parseLong(inScanner.next().replaceAll("\\+", ""),16);
            if(l {
                System.out.println(Long.toHexString(l).toUpperCase());
            }
        }
    }
}
