What is the best way to iterate over the lines of a Java String?

Question

Currently I\'m using something like :

String[]lines = textContent.split(System.getProperty(\"line.separator\"));
for(String tmpLine : lines){
   //do somethi

You can actually wrangle Scanner to allow you to use a normal for loop:

import java.util.Scanner;
public class IterateLines {
    public static void main(String[] args) {
        Iterable sc = () ->
            new Scanner("foo bar\nbaz\n").useDelimiter("\n");
        for (String line: sc) {
            System.out.println(line);
        }
    }
}

gives us:

$ javac IterateLines.java && java IterateLines 
foo bar
baz
