分词预处理java代码 java分词工具类

IT技术灵思

java如何分词？？如果你的分词规则是在一个字符串的开头和结尾加上"_"，然后两个字符一分的话，代码可以这样写：
import java.util.ArrayList;
import java.util.List;
public class Participle
{
private static final String HEAD_END_STR = "_";
private static final int PARTICIPLE_LENGTH = 2;
public static void main(String[] args)
{
String exampleWord = "计算机";
exampleWord = "_" + exampleWord + "_";
int length = exampleWord.length();
ListString result = new ArrayListString();
for (int i = 0; ilength - 1; i++)
{
String str = exampleWord.substring(i, i + PARTICIPLE_LENGTH);
result.add(str);
}
System.out.println(result);
}
}
输出结果：_计, 计算, 算机, 机_
在线等，比较急?。。∥矣胘ava版的结巴分词写了一段代码，怎样将它输出到指定的txt文件中？String str = segmenter.sentenceProcess(s);
System.out.println(str);
BufferedWriter out = new BufferedWriter(new FileWriter("F:\\out.txt"));
out.append(str);
