Why should I use LOOK_UP variable in enumeration that response for block damage?

Learning about block damage and subblocks I noticed that there is META_LOOKUP variable in every enumeration that response for damage. I even found this variable in enumeration of planks from source code of Minecraft. This variable stores all values of enumeration it is in.

I think META_LOOKUP variable is useless because you can just use values() for enumeration to get array of its values. Am I right?

Not really.

IIRC caching values in a static variable and using it to look up values is faster than using values() from an enum.

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.
