Re: [問題] 物件複製問題
借標題一用
爬了不少文章，clone()在某些情況下是管用的
但如果我的class裡面存在 二為陣列 clone 就派不上用場了
public class test_class implements Cloneable{
int a = 10;
int[] b = {1,2,3};
String[][] c = {{"A","B","C"},{"A","B","C"}};
public test_class clone(){
try{
test_class copy = (test_class)super.clone();
copy.b = (int[])b.clone();
copy.c = (String[][])c.clone();
return copy;
}
catch (CloneNotSupportedException e){
e.printStackTrace();
return null;
}
}
public static void main(String args[]){
test_class temp10 = new test_class();
test_class temp11 = temp10.clone();
temp10.a = 100;
teno10.b[1] = 100;
temp10.c[1][1] = "500";
System.out.println(temp10.a + " " + temp10.b[1] + " " + temp10.c[1][1]);
System.out.println(temp11.a + " " + temp11.b[1] + " " + temp11.c[1][1]);
}
顯示結果
100 100 500
10 2 500
表示class裡面變數為int,一維陣列都可順利複製，但二維陣列失敗
有解決辦法嗎?
明天就要交了...麻煩各位了，小弟在此感激不盡
