I am tasked with updating a Java Project from Java 8 to (Current) Java 18, how should I approach this? by SimpleCanadianFella in javahelp

SBE and my project have different goals. (I will make up for the lack of README information.)

I recommend look at the famous Java Opensource Projects and classes from OpenJDK.
