逐行读取字符串 [英] Read String line by line

问题描述

给定一个不太长的字符串，逐行读取它的最佳方法是什么？

Given a string that isn't too long, what is the best way to read it line by line?

我知道你可以这样做：

BufferedReader reader = new BufferedReader(new StringReader(<string>));
reader.readLine();

另一种方法是在eol上获取子字符串：

Another way would be to take the substring on the eol:

final String eol = System.getProperty("line.separator");
output = output.substring(output.indexOf(eol + 1));

还有其他更简单的方法吗？我对上述方法没有任何问题，只是想知道你们中是否有人知道看起来更简单，更有效的东西吗？

Any other maybe simpler ways of doing it? I have no problems with the above approaches, just interested to know if any of you know something that may look simpler and more efficient?

推荐答案

你也可以使用String的 split 方法：

You can also use the split method of String:

String[] lines = myString.split(System.getProperty("line.separator"));

这为您提供了方便数组中的所有行。

This gives you all lines in a handy array.

我不知道拆分的性能。它使用正则表达式。

I don't know about the performance of split. It uses regular expressions.
