uva-10815 - Andy's First Dictionary

题意：给你数个字符串，要你把字符串中的所以出现单词，不重复的按字典序输出。

思路：切割字符串，然后使用set存储单词

package test;import java.util.Scanner;import java.util.TreeSet;public class Test{static TreeSet<String> tree = new TreeSet<String>();public static void main(String[] args) {Scanner sc = new Scanner(System.in);String line = null;while(!"".equals((line=sc.nextLine().toLowerCase()))){for(String s : line.split(" ")){tree.add(s);}}System.out.println(tree);sc.close();}}
