How can I reference my Java Enum without specifying its type
I have a class that defines its own enum like this:
public class Test
{
enum MyEnum{E1, E2};
public static void aTestMethod() {
Test2(E1); // << Gives "E1 cannot be resolved" in eclipse.
}
public Test2(MyEnum e) {}
}
If I specify MyEnum.E1 it works fine, but I'd really just like to have it as "E1". Any idea how I can accomplish this, or does it have to be defined in another file for this to work?
CONCLUSION: I hadn't been able to get the syntax for the import correct. Since several answers suggested this wa开发者_Go百科s possible, I'm going to select the one that gave me the syntax I needed and upvote the others.
By the way, a REALLY STRANGE part of this (before I got the static import to work), a switch statement I'd written that used the enum did not allow the enum to be prefixed by its type--all the rest of the code required it. Hurt my head.
Actually, you can do a static import of a nested enum. The code below compiles fine:
package mypackage;
import static mypackage.Test.MyEnum.*;
public class Test
{
enum MyEnum{E1, E2};
public static void aTestMethod() {
Test2(E1);
}
public static void Test2(MyEnum e) {}
}
You can do a static import on a nested class:
import static apackage.Test.Enum.*;
The Test class has to be defined in a package to be importable.
With package defined in Test
(IT WORKS):
package mypackage;
You can use:
import static mypackage.Test.MyEnum.*;
Without package defined, you cannot use (DOES NOT WORK):
import static Test.MyEnum.*;
