Remove the line with unwanted characters from text file using java

问题

我想要过滤掉文本文件中包含许多未正确识别的单词的行。这些单词将通过特殊符号来识别,例如 @/(&#%-"。

例如,给定以下带有行的文件:

I like to eat.
I &^#@dj dsaasd.
I like to drink.

输出应该如下所示:

I like to eat.
I like to drink.

它将删除包含特殊符号的行。

英文:

I want to filter out the line in a text file which is having many words that were not recognize properly. The word will recognize with special symbols such as @/(&#%-"

For example the file given with lines:

I like to eat.
I &^#@dj dsaasd.
I like to drink.

And the output should be like:

I like to eat.
I like to drink.

It will remove the line with the special symbols.

读取文件内容作为行,你正在使用Java:

Stream<String> lines = Files.lines(path, encoding);

现在你需要应用你的过滤器:

lines.filter(line -> line.matches(你想要的正则表达式));

然后使用你想要的收集器。

要应用这个解决方案,你需要学习流(Streams)和lambda表达式,并且你使用的是Java 8及更高版本。

英文:

Read file content as lines, you are using java :

Stream&lt;String&gt; lines = Files.lines(path, encoding);

Now you need to apply your filter

lines.filter(line -> line.matches(regex that you want));

Then use the collector that you want

To apply this solution you need to learn Streams and lambda expression and you use java8 and higher.
