How do I add package level annotations or edit package-info.java?

I'm trying to add package level annotations but I don't have a clue on how to do it. Examples are appreciated.

Solution

  • Summary from the article here

    In package-info.java:

    @PackageLevelAnnotation
package blammy; // package with a package level annotation.


import blammy.annotation.PackageLevelAnnotation;

    In PackageLevelAnnotation.java

    package blammy.annotation;

@Retention(RetentionPolicy.CLASS)
@Target(ElementType.PACKAGE)
public @interface PackageLevelAnnotation
{
  // stuff as required.
}

    Edit: more package level info. Here is a link to the package chapter in the Java Language Spec: packages
