java实现数组的有序排列，并去除数组中重复元素

package _3_5_test;

import java.util.Arrays;
import java.util.Collection;
import java.util.Collections;
import java.util.HashSet;
import java.util.Iterator;
import java.util.TreeSet;

//测试数组倒序
//去除数组中重复的元素
public class FiftyFourTest {

    public static void main(String[] args) {

        String num[] = { "b", "a", "1", "3", "3", "2", "c" };

        TreeSet treeSet = new TreeSet(Arrays.asList(num));
        Iterator iterator = treeSet.iterator();
        while (iterator.hasNext()) {
            System.out.print(iterator.next() + " ");
        }

    }
