Java switch statement: Constant expression required, but it IS constant

Question

So, I am working on this class that has a few static constants:

public abstract class Foo {
    ...
    public static final int BAR;
    public static final          


        

Answer 1

I recommend using the following way:

public enum Animal {
    DOG("dog"), TIGER("tiger"), LION("lion");
    private final String name;

    @Override
    public String toString() {
        return this.name;
    }
}


public class DemoSwitchUsage {

     private String getAnimal(String name) {
         Animal animalName = Animal.valueOf(name);
         switch(animalName) {
         case DOG:
             // write the code required.
             break;
         case LION:
             // Write the code required.
             break;
         default:
             break;
         }
     }
}
