static imports: from sun's pre-assesment

[Vishwanath Krishnamurthi]

Hi Ranchers,

[Q.no 37, sun pre-assesment test.. they dont give the answers ]

  Given two files:
 

1. package x;
2. public class StaticStuff {
3.   public static enum Color {BLUE, RED };
4.   public static StaticStuff ss;
5.   public static void go() { }
6. }
 
And:
 

1. import static x.StaticStuff.*;
2. class FindStatic {
3.   public static void doStuff() {
4.     Color c = Color.BLUE;
5.     ss = new StaticStuff();
6.     go();
7. } }
 
  

When class StaticStuff has been compiled, what is the result when you attempt to compile class FindStatic?

The code compiles.
Compilation fails due to an error on line 1.
Compilation fails due to an error on line 4.
Compilation fails due to an error on line 5.
Compilation fails due to an error on line 6.
Compilation fails due to errors on multiple lines.

I had chosen option1 but I think I was wrong...
Is it the option three?
Static import only imports the static member so there's no way to instantiate StaticStuff in FindStatic??

Thanks...

I think you have chosen the correct answer, we can not import like

import static x.StaticStuff.*;

Thanks!

Correct answer is: Compilation fails due to an error on line 5.
The compiler cannot recognize the StaticStuff.
Need to add import com.test.StaticStuff;

The error is on line 5.
ss = new StaticStuff();

Although you have imported the static members, but to instantiate the StaticStuff class, you need to use the package name. Try using

ss = new x.StaticStuff();

It will compile fine.

Hope this helps
