If you're just starting out in Java, I'd recommend going through the official tutorials from Oracle, in order: https://docs.oracle.com/javase/tutorial/

You want to do all the "Trails covering the basics".  It's a bit of a dry grind, but will really help lay a solid foundation that you can then branch off of in different directions.

For a code editor, I recommend IntelliJ.  It's what I use at work and has full support for the Java language.  This tutorial will show you how to get started with IntelliJ.  The code example presented is a bit complex for absolute beginners, but the basic concepts of how to setup a project structure are applicable to pretty much any program: https://examples.javacodegeeks.com/desktop-java/ide/intellij-idea-tutorial-beginners/

This online course series also looks really good for just starting out, although I haven't tried it myself: https://www.udemy.com/java-tutorial/

Have fun and good luck!
