package collection;
import java.util.*;

public class ListTest {

  public ListTest(){
  }

public static void test(){

List list = new ArrayList();//如果有一天
list.add(new Student(2,"Tom"));
list.add(new Student(3,"Bonny"));
list.add(new Student(7,"Jack"));
list.add(new Student(4,"Steven"));
list.add(new Student(5,"Smith"));
list.add(new Student(6,"Jane"));

List linkedList = new LinkedList(list);

list.set(1,new Student(3,"NewBonny"));

System.out.println(linkedList);

}

  public static void main(String[] args) {
   ListTest.test();
  }
}
其中这一句 list.set(1,new Student(3,"NewBonny"));并不改变list中的值，小弟刚开始学java，理解的不是很深刻，请大家指教！

value of list is the reference or address of the list.

If you move some furniture into your hourse, it does not change the address of your hourse. The address of your hourse is the value of your hourse. The value of your hourse does not change!!!!
