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         


        

Answer 1

I believe you have a better API available starting with Java-11 where you can do the same using the String.lines() API which returns the stream of strings extracted from this string partitioned by line terminators.

public Stream lines()

Usage of the same could be:-

Stream linesFromString = textContent.lines();
linesFromString.forEach(l -> {  //do sth });

Important API Note :-

@implNote This method provides better performance than
          split("\R") by supplying elements lazily and
          by faster search of new line terminators.
