使用Java搜索文件内容？ [英] Searching a Files Content Using Java?

问题描述

我想用java编写一个应用程序，它允许我打开文件（txt）并使用用户输入，搜索特定单词或字符串的所有实例。

由于这里可能会有更多经验丰富的程序员，所以我想就如何创建这样的工具提供一些建议。如何创建一个基本的文本搜索工具？

我一直在玩一些java类，如File，FileOutputStream，FileInputStream，InputStreamReader，OutputStreamReader，FileReader， StreamTokenizer，并想知道使用java打开和搜索文件的最佳方式？

感谢您的任何输入，

解决方案使用文件和扫描仪和一个 StringBuilder 应该给你一个很好的开始。

I would like to write an application, in java, that allows me to open a file (txt) and using the users input, search for all instances of a particular word or string.

As there are probably more experienced programmers here, i would like some advice about how to go about creating such a tool. How would you go about creating a basic text search tool?

I have been playing around with some java classes such as File, FileOutputStream, FileInputStream, InputStreamReader, OutputStreamReader, FileReader, StreamTokenizer and would like to know the optimal way to open and search a file using java?

Thanks for any input you may have, Des.

解决方案

Using a File with a Scanner, and a StringBuilder should give you a good start into that topic.
