Can Java enum be iterated?

Question

Can I do something like me[1] or MyEnum[1]? If I have:

enum MyEnum {e1,e2,e3,e4}; //... MyEnum me;

I have tried it, but it seems to generate errors. Is it another way to do it, or I can use just things like MyEnum.e2?

MyEnum.values() return MyEnum[] where you can put index

MyEnum[] me=MyEnum.values();
MyEnum secVal= me[1]; //it will return e2.

Answer 2

MyEnum.values() is what you might be looking for.
