Execution order of Enum in java

Question

I got a question about Enum.

I have an enum class looks like below

public enum FontStyle {
    NORMAL(\"This font has normal style.\"),
    BOLD(\"T         


        

Answer 1

The enum instances are created only once, when the Enum class itself is loaded.

It is very important that they are created only once, so that object identity comparison works (==). Even the object (de)serialization mechanism had to be adjusted to support this.
