Getting java enum by name

Question

Is it possible to get an enum by searching on its name instead of value ? For example :

public enum MyEnum {
    TOTO("some value", 1);
    ZOZO("some other value", 2);
}

And what I want to do is a getter like :

public static MyEnum getByName(String str) {
    [...]
}

So I can do :

MyEnum foo = MyEnum.getByName("TOTO");
MyEnum bar = MyEnum.getByName("ZOZO");

Use the built-in `MyEnum.valueOf(name)`. – Luciano van der Veekens Aug 29 '17 at 07:28 — Luciano van der Veekens, Aug 29 '17 at 07:28

Each Java enum has method valueOf(String name) which returns enum by name.

MyEnum foo = MyEnum.valueOf("TOTO");
MyEnum bar = MyEnum.valueOf("ZOZO");

What is wrong with this answer? – xenteros Aug 29 '17 at 07:29
Okay I misunderstood the javadoc... But in this case wouldn't it be better to use `MyEnum.valueOf(MyEnum.class, "TOTO")` ? – Dynamite Aug 29 '17 at 07:39
@Dynamite There is no reason for that. Trust me :) – xenteros Aug 29 '17 at 07:41

@Dynamite that would only be useful if the first parameter were only known at runtime, e.g. you've just got a variable `Class extends Enum>> someClass`. – Andy Turner Aug 29 '17 at 07:42
