Question

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

I know you can do:

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

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));

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?

Answer 1

You can also use the split method of String:

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

This gives you all lines in a handy array.

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