Question
Given this declaration:
@Target(TYPE)
@interface Resource {}
For which two kinds of declarations can the @Resource annotation be applied? (Choose two.)
A. An interface declaration
B. A local variable declaration
C. A class declaration
D. A method declaration
E. A field declaration
Answer
C. A class declaration
E. A field declaration
Explanation
The @Resource annotation is used in Java for resource injection, typically for dependency injection in Java EE applications. According to the given declaration, the @Target annotation specifies that the @Resource annotation can only be applied to TYPE declarations.
In Java, TYPE includes class and interface declarations, as well as enum declarations and annotation type declarations. Therefore, the @Resource annotation can be applied to class declarations and interface declarations.
However, it cannot be applied to local variable declarations (option B), method declarations (option D), or any other kind of declaration besides TYPE.
By selecting options C and E, we correctly identify that the @Resource annotation can be applied to class declarations and field declarations, which are both considered TYPE declarations in Java.
