java自带的大数类，调用方法相加即可

import java.util.Scanner;
import java.math.BigDecimal;

public class Main{
    public static void main(String[] args){
        Scanner scanner = new Scanner(System.in);
        try {
            while (scanner.hasNext()) {
                BigDecimal num1 = new BigDecimal(scanner.next());
                BigDecimal num2 = new BigDecimal(scanner.next());
                System.out.println(num1.add(num2));
            }
        } catch (Exception e) {

        } finally {
            scanner.close();
        }
    }
}
