Creating Custom Annotation in Java to force UPPER or lower Case

Question

Appreciate any help for creating custom annotation in JAVA by forcing Upper or Lower case for a pojo field. Like to get something like below

// CaseMode enum wou         


        

Answer 1

Your statement // NEED HELP HERE should be according to the following:

@Target({ElementType.FIELD, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface Case {
    CaseMode value();
}

If you think that you can have some code in there then you are wrong.
