推荐答案

有很多方法可以做到这一点，一个更清晰的问题会有所帮助.

如果您有单词列表，可以尝试:

There are a lot of ways to do this and a clearer question would have helped.

If you have a list of words, you could try:

for each word in list
  if word contains search
    output word

如果您只有原始文字:

If you only have the raw text:

for each occurance of search in text
  highlight search
output highlighted text

再一次，您可以为单词及其出现的文档建立索引.这将更加有趣，因为您需要知道哪些完整的单词可以包含您的搜索词.在这里，您可以执行提取搜索词两侧的文本以输出每个文档的标准.

一开始，他们的实际需求尚不清楚，因此我无法为您提供真实的代码.

Then again you could have an index of words and the documents they occur in. This will be more fun as you''ll need to know which full words can contain your search term. Here you can do the standard of extracting the text either side of the search term to output for each document.

As I started, they actual requirement is unclear and so I have not been able to give you real code.

Update your question with more detail and I will endevour to give you more of an answer.

使用StringTokenizer，例如StringTokenizer tkn = new StringTokenizer(StringToBeSeached，StringToSeach);

请注意，在具有要查找的主字符串之后，应该初始化令牌生成器，因此您不能在之前分配令牌生成器.例如，如果您打算从文件中读取字符串，并查看它们是否包含子字符串，则每次从文件中读取新字符串时都必须初始化令牌生成器.

Use StringTokenizer e.g StringTokenizer tkn = new StringTokenizer( StringToBeSeached, StringToSeach);

Notice that you should initialize tokenizer after you have you main string to look-in, so you cant allocate tokenizer before. For example, if you are intended to read strings from a file and look in them if they have a sub-string you seach then you have to initialize tokenizer each time you read a new string from the file.
