我正在编写一个程序,它将添加 2 个长度为 40 个元素的数组。我必须将 add() 方法保留为 HugeInteger(不能将其更改为整数),因此当我尝试返回 2 个整数的总和时,它会给我“HugeInteger@77e1ee5d”。有人可以让我知道这意味着什么,并告诉我如何解决它。谢谢
公共类 HugeInteger {
private int[] integer ;
public HugeInteger(int num[]){
integer =new int [40];
for(int x=1; x<=39; x++){
integer[x]= num[x];
}
}
public void parse(String s){
for(int i=0; i<=s.length(); i++){
integer[i]=Integer.parseInt(s.substring(i,i+1));
}
}
public HugeInteger add(HugeInteger a1){
HugeInteger sum = new HugeInteger(integer);
int cary=0;
for (int i=39; i>=0; i--){
sum.integer[i]=integer[i]+a1.integer[i]+cary;
if(sum.integer[i]>=10){
cary=1;
sum.integer[i]-=10;
}else{
cary=0;
}
}
return sum;
}}
//这是我的测试程序
public class HugeIntegerTest {
public static void main(String[] args) {

HugeInteger hi= new HugeInteger(num);
System.out.println("Addition: "+hi.add(hi));
