使用 StreamTokenizer类获得文本中的单词和数字个数

package com.utils;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.StreamTokenizer;

public class WordCount {

public static void main(String[] args) {
// TODO 自动生成的方法存根
File file = new File("D://tmp/unZipFile.txt");
int wordCounter = 0;
int numberCounter = 0;
FileReader reader = null;
try {
reader=new FileReader(file);
StreamTokenizer st=new StreamTokenizer(reader);
while(st.nextToken()!=StreamTokenizer.TT_EOF){
switch(st.ttype){
case StreamTokenizer.TT_NUMBER:
numberCounter++;
break;
case StreamTokenizer.TT_WORD:
wordCounter ++;
break;
}
}
} catch (FileNotFoundException e) {
// TODO 自动生成的 catch 块
e.printStackTrace();
} catch (IOException e) {
// TODO 自动生成的 catch 块
e.printStackTrace();
}
System.out.println( wordCounter );
System.out.println( numberCounter );
}

}
