一段能验证ArrayList的clone()方法是浅拷贝的代码

import java.util.*; public class ArrayListShadowCloneTest { public static void main(String[] args) { ArrayList<Student> list = new ArrayList<>(); //添加两个元素 Student stJack=new Student("Jack", 13); Student stTom=new Student("Tom", 15); list.add(stJack); list.add(stTom); //克隆 ArrayList<Student> listCopy=(ArrayList<Student>) list.clone(); stJack.setName("balbaol"); //改变stJack的name，导致list和listCopy都改变，验证了浅拷贝 System.out.println(list.get(0).toString()); System.out.println(listCopy.get(0).toString()); } static class Student{ private String name; private int age; public void setName(String name){ this.name = name; } Student(String name, int age){ this.name = name; this.age = age; } @Override public String toString() { return "Student{" + "name='" + name + '\'' + ", age=" + age + '}'; } } }
