Question on Static import!!

[Krishna Srinivasan]

static imports:
===============

  
 
import static pack.Enum.EnumMember.Java;
import static pack.Enum.EnumMember.J2EE;
import static pack.Enum.EnumMember.J2ME;
import static pack.Enum1.EnumMember.*;
 
public class Test4{
public static void main(String args[]){
 System.out.printf("%s : ",Java);
 System.out.printf("%s : ",J2EE);
 System.out.printf("%s : ",J2ME);
}
}
 
/*
 
What will be the output?
 
1)Java : J2EE : J2ME
2)Java1 : J2EE1 : J2ME1
3)Compiler Error
 
*/
 
package pack;
public class Enum{
public enum EnumMember{
Java,
J2EE,
J2ME,
}
}
 
package pack;
public class Enum1{
public enum EnumMember{
Java1,
J2EE1,
J2ME1,
}
}

Nice question. Brett's Devloper notes has a good explanation

1 is the answer The same question could be extended to static methods.

Surprising Static Imports

[Krishna Srinivasan]

few tips on static import:

Two types of static import declarations:

1)single-type import declaration.
example:
import static Enum.EnumMember.Java;
2)static import on demand.
example:
import static Enum.EnumMember.*;


On-demand-static import never shadow the previous imports declarations.
example:
import static Enum.EnumMember.Java;
import static Enum1.EnumMember.*;

In the above example both the enum type has the variable Java.When we are usiing
the on-demand-static-import(import static Enum.EnumMember1.* .It will not shadow
the previous declaration import static Enum.EnumMember.Java;

But two single-type static imports trying to import the same variable, the compile
time error occurs.

example:
import static Enum.EnumMember.Java;
import static Enum1.EnumMember.Java;
