Jackson is "the Java JSON library" or "the best JSON parser for Java". Or simply as "JSON for Java".

Jackson Annotations Source Code files are provided in the source packge (jackson-annotations-2.14.0-sources.jar). You can download it at Jackson Maven Website.

import java.lang.annotation.Target;

/**
 * Annotation that can be used to define ordering (possibly partial) to use
 * when serializing object properties. Properties included in annotation
 * declaration will be serialized first (in defined order), followed by
 * any properties not included in the definition.
 * Annotation definition will override any implicit orderings (such as
 * guarantee that Creator-properties are serialized before non-creator
 * properties)
 *<p>
 * Examples:
 *<pre>
 *  // ensure that "id" and "name" are output before other properties
 *  &#64;JsonPropertyOrder({ "id", "name" })
 *  // order any properties that don't have explicit setting using alphabetic order
 *  &#64;JsonPropertyOrder(alphabetic=true)
 *</pre>
 *<p>
 * This annotation may or may not have effect on deserialization: for basic JSON
 * handling there is no effect, but for other supported data types (or structural
 * conventions) there may be.
 *<p>
 * NOTE: annotation is allowed for properties, starting with 2.4, mostly to support
 * alphabetic ordering of {@link java.util.Map} entries.
