用java创建TreeSet集合完成以下操作： 样例输入： Person p1=new Person("001","tt",27); Person p4=new Person("001","tt",29); Person p2=new Person("005","tt1",23); Person p3=new Person("006","tt2",27); Person p5=new Person("007","tt3",22); Person p6=new Person("007","tt3",40); 样例输出： 001---tt---27 001---tt---29 005---tt1---23 006---tt2---27 007---tt3---22 007---tt3---40

好的，下面是代码实现：

import java.util.TreeSet;

public class Main {
    public static void main(String[] args) {
        TreeSet<Person> set = new TreeSet<>();
        Person p1 = new Person("001", "tt", 27);
        Person p4 = new Person("001", "tt", 29);
        Person p2 = new Person("005", "tt1", 23);
        Person p3 = new Person("006", "tt2", 27);
        Person p5 = new Person("007", "tt3", 22);
        Person p6 = new Person("007", "tt3", 40);

        set.add(p1);
        set.add(p4);
        set.add(p2);
        set.add(p3);
        set.add(p5);
        set.add(p6);

        for (Person p : set) {
            System.out.println(p);
        }
    }
}

class Person implements Comparable<Person> {
    private String id;
    private String name;
    private int age;

    public Person(String id, String name, int age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }

    @Override
    public String toString() {
        return id + "---" + name + "---" + age;
    }

    @Override
    public int compareTo(Person o) {
        if (this.age != o.age) {
            return Integer.compare(this.age, o.age);
        } else if (!this.name.equals(o.name)) {
            return this.name.compareTo(o.name);
        } else {
            return this.id.compareTo(o.id);
        }
    }
}

这个代码实现了一个名为`Main`的类，创建了一个`TreeSet`集合，并添加了6个`Person`对象。然后，遍历集合并输出每个`Person`对象的信息。`Person`类实现了`Comparable`接口，通过重写`compareTo()`方法，实现了按`age`、`name`、`id`的顺序进行比较，并且重写了`toString()`方法，输出了`Person`对象的信息。
