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          


        

Answer 1

You can use the stream api and a StringReader wrapped in a BufferedReader which got a lines() stream output in java 8:

import java.util.stream.*;
import java.io.*;
class test {
    public static void main(String... a) {
        String s = "this is a \nmultiline\rstring\r\nusing different newline styles";

        new BufferedReader(new StringReader(s)).lines().forEach(
            (line) -> System.out.println("one line of the string: " + line)
        );
    }
}

Gives

one line of the string: this is a
one line of the string: multiline
one line of the string: string
one line of the string: using different newline styles

Just like in BufferedReader's readLine, the newline character(s) themselves are not included. All kinds of newline separators are supported (in the same string even).
