java中如何将list1赋值给另外一个list2

RT，我想将list1的一部分值赋值给list2，该怎么做呢？

Answer 1

Article a = articles.<a href="https://www.baidu.com/s?wd=get&tn=44039180_cpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1dBm10knAD1nyFhm1K-mWnz0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6K1TL0qnfK1TL0z5HD0IgF_5y9YIZ0lQzqlpA-bmyt8mh7GuZR8mvqVQL7dugPYpyq8Q1DvnjRvPWRznHbYnjnYnHb4rjT" target="_blank" class="baidu-highlight">get</a>(i);
ArticleVirtual av = new ArticleVirtual();
av.setId(a.getId());

每个属性都get出来，再set进去就可以了。

Answer 2

list1.subList(int fromIndex, int toIndex);
希望能够帮助到你！

Answer 3

public class Runmain
{
List<Object> list=new ArrayList<Object>();
public static void main(String[] args)
{
Runmain run=new Runmain();
run.listArray();
run.add(run.list);
}

public void listArray()
{

list.add(0);
list.add(1);
list.add("s");
System.out.println(list);
}

public void add(List list)
{
List ss=list;
System.out.println(ss);
}
}
