Setting up

Three things to settle before the notes are any use.

You need a JDK, somewhere to type, and a machine that does not get in the way. None of it takes long, and all three are places people lose an afternoon to a problem that has a one-line answer.

Notes in this section

  • Choosing an editor

    An IDE is a large amount of help. Early on, some of that help is in the way.

  • Installing a JDK

    You need a JDK, not a JRE, and it matters less which one than people suggest.
