jakarta.annotation Paketi

Giriş

Açıklaması şöyle

The jakarta.annotation package is a Java package used for defining standard annotations that can be used in Java applications, particularly in Jakarta EE (Enterprise Edition) applications.

This package contains a set of annotations that can be used to provide additional information about Java code, such as indicating whether a parameter can be null or not, or providing hints to the compiler to suppress certain warnings.

Some of the commonly used annotations in the jakarta.annotation package include:

Nonnull: Indicates that a parameter, field, or method return value cannot be null.

Nullable: Indicates that a parameter, field, or method return value can be null.

PostConstruct: Indicates a method to be executed after dependency injection is done by the container.

PreDestroy: Indicates a method to be executed when the container destroys an instance of a class.

The jakarta.annotation package is included in Jakarta EE and is a replacement for the similarly named javax.annotation package used in earlier versions of Java EE.
