Java 11 - New String Features

Java 11 introduced several new features, but the most notable and useful to most of our daily work routines resolves around new String class methods. We will discuss a few here.

String.isBlank() returns a boolean value indicating whether or not a string is empty or contains only white space. It returns true if the String is empty or contains only whitespace.

String.lines() returns a Stream of lines extracted from a string. So if you have a String composed of several new lines (/n), it will convert that String into a Stream where each element in the Stream is one of those lines. Then from there, you can convert the Stream to a List, etc.

String.repeat() just repeats the given String how every many times you request. So something like "*".repeat(10) would give you a string containing "**********".
