Replacement for Java 11 method String.isBlank() in Java 8

Question

I have a project developed in Java 11 and have to adapt in another, but using Java 8.

Some part of this Java 11 project uses the String method isBlank(), that is not recognized in Java 8. What is the best approach to adapt this method in Java 8 project?

You can very well write your own implementation if you care to look into the implementation. The post linked suggests *Before Java 11* implementation as well. — Naman, Dec 20 '19 at 13:19

Best approach would be to use Apache Commons StringUtils.isBlank(String)

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.9</version>
</dependency>

uses a commonly used library
proven
uses centralized code
is very similar to the source that has to be converted
Not falling for 'Not invented here' syndrome
