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: B,C

AI Explanation

To determine which code fragments, when inserted individually at line 2 of the Beta declaration, will allow the code to compile, let's go through each option:

Option A) import sun.scjp.Color.; This option is incorrect because it imports all the members of the Color enum using the wildcard (). However, since the Color enum is in a different package, it cannot be accessed using the wildcard import.

Option B) import sun.scjp.Color; import static sun.scjp.Color.*; This option is correct because it imports the Color enum and allows static access to its members. The static import statement makes it possible to refer to the enum values (RED, GREEN, BLUE) directly, without specifying the enum class name.

Option C) import sun.scjp.Color; import static sun.scjp.Color.GREEN; This option is correct because it imports the Color enum and statically imports only the GREEN member. This allows the code to compile as it can directly refer to GREEN without specifying the enum class name.

Option D) import static sun.scjp.Color.*; This option is incorrect because it tries to statically import all the members of the Color enum. However, since the enum itself is not imported, the code will not compile.

Therefore, the correct options are B and C.
