enum

[Raju Champaklal]

why is this illegal?
enum Test{ a,b,3}; i think enum are used to hold any values so that we can limit the values

  class M
{
    static class M1
    {
        enum Test{ a,b,c};//legal
}
 static void m()
    {
           enum Test2{ a,b,c};//illegal?
    }
  
    }
    

public class EnumTest {enum Test1{ a,b,c};
EnumTest.Test1 t=EnumTest.Test1.a;
M.M1.Test g=M.M1.Test.b;
}  

this is possible even though K&B says that enum cannot be in a method....then why in a static class? and why not in a static method?

[Neha Daga]

because a static inner class is actually a top level nested class.

and an enum is a list of constant values assigned to a type.

[Raju Champaklal]

isnt 3 a constant? what if i create a enum Test{1,2,3}?

[Neha Daga]

but 3 is different type then a&b.

i think enum{1,2,3} will do.

enum{1,2,3} doesnt compile...

From the JLS

Nested enum types are implicitly static. It is permissable to explicitly declare a nested enum type to be static.

This implies that it is impossible to define a local enum, or to define an enum in an inner class

How is enum {1,2,3} supposed to compile?? Is 1 or 2 or 3 a legal identifier??
