TreeSet：二叉树有序，存自定义对象时的排序问题cannot be cast to java.lang.ComparableComparable=可比较的a.Sourceb.Alt+Shift+S 可以调出重写方法的菜单c.跟错误提示走方法一：传入的对象所属的类，必须实现Comparable方法二：初始化TreeSet时，传入一个比较器（比较器是一个实现了Comparator的类的对象）作为一
import java.util.*;public class ab {public static void main(String[] args) {TreeSet<String> set = new TreeSet<String>(); set.add("justin");set.add("caterpillar"); set.add("momor");set.add("justin");Iterator<String> iterator = set.iterator();
