If I have a bunch of enum instances in an enum type, and if I access an instance of it the first time, all of its remaining instances too are initialized at the same time. Is there any way to initialize an enum instance only when it’s accessed the first time?
Not without basically making it not an
enumanymore. Enums are classes. The first time a class is used, it gets loaded by the JVM and all of its static initialization is done. Setting up the enum members is a static initialization, so they’re all going to be initialized.
