compare values in enum java

Question

So here is my situation I am comparing two situations of the WallEnums to the rest of them.

import static com.gowallgo.enumtypes.WallEnums.CAW;
"" ( and the rest )


   /**
     * {@link Set} of cancel {@link WallEnums}s
     */
    private static final Set<WallEnums> WALL_CODES = asSet(RES, CAW, AAP, ASV, CQP, OQR);


// more stuff and then I use it here . 

if (wallEnum != WALL_CODES.contains(wallEnum)){}

this begs for refactoring . where should I start so I don't need to make a static import for each code ?

What is this supposed to do? if (wallEnum != WALL_CODES.contains(wallEnum)){} compare an enum value to a boolean? — tobias_k

If you don't want to import every enum value you can use

import com.gowallgo.enumtypes.WallEnums

WallEnums enum = WallEnums.RES;  //Now you have to use EnumName.VALUE

Use EnumSet:

// Do not import anything

// This creates a Set that contains all posible values
// In case you need a subset use: EnumSet.of(WallEnums.RES, WallEnums.CAW, etc)
private static final Set<WallEnums> WALL_CODES = EnumSet.allOf(WallEnums.class);

// Later...
if (WALL_CODES.contains(someWallEnum)) {
    // Do stuff if someWallEnum belongs to WALL_CODES set
}

This code creates a set of enums using optimized EnumSet class. Then you could use any Set operation as usual, i.e contains().

You dont have to import each enum type, You could try importing every element of enum using:

import static com.gowallgo.enumtypes.WallEnums.*;

The code environment does not allow imports with a star ( idk why , just one of those glitch type things ) I should have mentioned this.
