java问题:统计用户输入的一段文字的字符个数、单词数、和句子个数！

import java.util.HashMap;
import java.util.Map;
import java.io.*;

public class test{

private static String WORD = "0";

private static String SENTENCE = "1";

public static Map<String, Integer> getCount(String str) {
str = str.replace(".", "#");
str = str.replace("?", "#");
str = str.replace("!", "#");

int wordCount = str.split(" ").length;
int sentenceCount = str.split("#").length;
Map<String, Integer> map = new HashMap<String, Integer>();
map.put(WORD, wordCount);
map.put(SENTENCE, sentenceCount);
return map;
}

public static void main(String[] args) throws NumberFormatException, IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
String x=br.readLine();
Map<String, Integer> map = getCount(x);
System.out.println("单词数量： "+map.get(WORD));
System.out.println("句子数量： " + map.get(SENTENCE));
}

}

单词数，，输入的是中文还是英文啊？
