Last Updated : 03 Jan, 2020

The getDeclaredAnnotations() method of java.lang.Package class is used to get the declared annotations present in this class. The method returns an array of declared annotations present. Syntax:

 public DeclaredAnnotation[] getDeclaredAnnotations()

Parameter: This method does not accepts any parameter. Return Value: This method returns an array of declared annotations present. Below programs demonstrate the getDeclaredAnnotations() method. Example 1:

Java

// Java program to demonstrate // getDeclaredAnnotations() method import java.util.*; import java.lang.annotation.*; @Deprecated public class Test {  public Object obj;  public static void main(String[] args)  throws ClassNotFoundException  {  try {  // returns the Class object for this class  Class myClass = Test.class;  System.out.println(  "Class represented by myClass: "  + myClass.toString());  // Get the declared annotation  // using getDeclaredAnnotations() method  System.out.println(  "DeclaredAnnotation of myClass: "  + Arrays.toString(  myClass.getDeclaredAnnotations()));  }  catch (Exception e) {  System.out.println(e);  }  } }

Output:

 Class represented by myClass: class Test DeclaredAnnotation of myClass: [@java.lang.Deprecated()]

Example 2:

Java

// Java program to demonstrate // getDeclaredAnnotations() method import java.util.*; import java.lang.annotation.*; // create a custom DeclaredAnnotation @Retention(RetentionPolicy.RUNTIME) @interface DeclaredAnnotation {  // This declared annotation has two attributes.  public String key();  public String value(); } // call DeclaredAnnotation for method // and pass values for declared annotation @DeclaredAnnotation(key = "GFG", value = "GeeksForGeeks") public class Test {  public Object obj;  public static void main(String[] args)  throws ClassNotFoundException  {  // returns the Class object for this class  Class myClass = Test.class;  System.out.println(  "Class represented by myClass: "  + myClass.toString());  // Get the declared annotation  // using getDeclaredAnnotations() method  System.out.println(  "DeclaredAnnotation of myClass: "  + Arrays.toString(  myClass.getDeclaredAnnotations()));  } }
