17,323 PointsHow to return empty string array in the default value in java annotation ?
It returns an error every time I run this code that the hashtags element should return an empty string array and I don't know what I did wrong. Thanks in advance. . .
import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target; import java.lang.annotation.ElementType;
@Retention(RetentionPolicy.RUNTIME) @Target({ElementType.TYPE, ElementType.METHOD}) public @interface LiveTweet { String username() default ""; String[] hashtags() default ""; }

Courses Plus Student 56,696 PointsYou only need to change one thing. Your default value for String[] hashtags() should be {} not "". The double quotes are for an empty string while the curly braces are for an empty array.
Hope this helps.
