Hi guys! I was trying out enums. The following code works fine.

Output is


Now next i was trying to use enum CoffeeSize directly. Here is the code

It shows me the following error.


What does it mean? I din't understand why CoffeeSize is not initialized here and what is happening in previous code regarding this.

This has nothing to do with enums.

You may not access a variable before it's initialized. Member variables get initialized to a default value automatically, if you don't assign a value to them. Local variables do not, you always have to assign a value to them explicitly.
 
It is sorta covered in the JavaRanch Style Guide.
