Things to Consider When Choosing a Java Development Tool

Finalize Your JDK Distribution

A JDK distribution is the first item you'll need for Java development. AdoptOpenJDK is generally the safest bet if you don't have any specific needs. It's best to use a separate JDK implementation for local development if your firm has chosen a different JDK implementation, because production parity in your local environment is always the end goal.
