java - Read String line by line

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

There is also Scanner. You can use it just like the BufferedReader:

Scanner scanner = new Scanner(myString);
while (scanner.hasNextLine()) {
  String line = scanner.nextLine();
  // process the line
}
scanner.close();

I think that this is a bit cleaner approach that both of the suggested ones.
