方法：将list或者arraylist中的数据加载到linkedhashset中 然后在加载到list或者arraylist中
测试用例如下：
public class TestSet {public static void main(String[] args) {List<Student> list1 = new ArrayList<Student>();list1.add(new Student("张三","12"));list1.add(new Student("张三","12"));list1.add(new Student("李四","12"));list1.add(new Student("王五","15"));list1.add(new Student("张三","12"));list1.add(new Student("张三","13"));System.out.println(list1.toString());Set<Student> set = new LinkedHashSet<Student>();set.addAll(list1);List<Student> list2 = new ArrayList<Student>();list2.addAll(set);System.out.println(list2.toString());}}
对象：
public class Student {String name;String age;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getAge() {return age;}public void setAge(String age) {this.age = age;}@Overridepublic int hashCode() {final int prime = 31;int result = 1;result = prime * result + ((age == null) ? 0 : age.hashCode());result = prime * result + ((name == null) ? 0 : name.hashCode());return result;}@Overridepublic boolean equals(Object obj) {if (this == obj)return true;if (obj == null)return false;if (getClass() != obj.getClass())return false;Student other = (Student) obj;if (age == null) {if (other.age != null)return false;} else if (!age.equals(other.age))return false;if (name == null) {if (other.name != null)return false;} else if (!name.equals(other.name))return false;return true;}@Overridepublic String toString() {return "Student [name=" + name + ", age=" + age + "]";}public Student(String name, String age) {super();this.name = name;this.age = age;}public Student() {// TODO Auto-generated constructor stub}}
结果
，所有的胜利，与征服自己的胜利比起来，都是微不足道
