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();

List<String> result = new ArrayList<String>();

for (int i = 0; i < length - 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_
