Question

怎么用正则表达式中表示所有的单词字符信息

Answer 1

this.openReader();

String lineStr = new String();
int countOfWord = 0;
Pattern patternOfWord = Pattern.compile("这里要写上正则表达式");
Matcher m;

try {
while ( (lineStr = this.in.readLine()) != null ){
m = patternOfWord.matcher(lineStr);
if (m.matches())//如果匹配
countOfWord++;//则+1
}
this.closeReader();
return countOfWord;
}
