复制代码 代码如下:

package action;

import java.util.Arrays;

import java.util.TreeSet;

public class test {

/**

* @param args

*/

public static void main(String[] args) {

String strs = "ZZZ BBB AAA OOO ZZZ AAA ZZZ BBB AAA ZZZ AAA VVV OOO CCC DDD CCC CCC KKK BBB AAA ZZZ AAA CCC KKK";

String[] word = strs.split(" ");

TreeSet<String> set = new TreeSet();//去重复使用TreeSet

//排序

Arrays.sort(word);

//计算出现个数

for (int i = 0; i < word.length; i++) {

int count = 0;

for (int j = 0; j < word.length; j++) {

if (word[i].equals(word[j])) {

count += 1;

}

}

set.add(word[i]+":"+count);

}

//去重复

for(String s:set){

System.out.println(s);

}

}

}
