Given: 1. package sun.scjp; 2. public enum Color { RED, GREEN, BLUE } 1. package sun.beta; 2. // insert code here 3. public class Beta { 4. Color g = GREEN; 5. public static void main( String[] argv) 6. { System.out.println( GREEN); } 7. } The class Beta and the enum Color are in different packages. Which two code fragments, inserted individually at line 2 of the Beta declaration, will allow this code to compile? (Choose two.)

Correct Option: C,E

AI Explanation

To answer this question, we need to understand the concept of importing packages and static members.

In the given code, the class Beta and the enum Color are in different packages. To access the enum Color in the class Beta, we need to import it. Additionally, since the enum Color is defined using the "enum" keyword, we can import its static members individually.

Let's go through each option to understand why it is correct or incorrect:

Option A) import sun.scjp.Color.*; This option is incorrect because it imports all the members (including non-static members) of the Color enum. It does not allow us to access the enum values directly without specifying the enum name.

Option B) import static sun.scjp.Color.*; This option is incorrect because it imports all the static members of the Color enum. It does not import the enum itself. Therefore, we won't be able to access the enum values directly without specifying the enum name.

Option C) import sun.scjp.Color; import static sun.scjp.Color.*; This option is correct because it imports the Color enum and its static members individually. It allows us to access the enum values directly without specifying the enum name.

Option D) import sun.scjp.; import static sun.scjp.Color.; This option is incorrect because it imports all the members of the sun.scjp package, including non-static members of the Color enum. It does not import the enum itself. Therefore, we won't be able to access the enum values directly without specifying the enum name.

Option E) import sun.scjp.Color; import static sun.scjp.Color.GREEN; This option is correct because it imports the Color enum and only the GREEN static member. It allows us to access the GREEN enum value directly without specifying the enum name.

The correct answers are C and E.
