The getDeclaredAnnotations() method of java.lang.AnnotatedElement class is used to get the declared annotations present in the class implementing this interface. 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 program to demonstrate // getDeclaredAnnotations() method import java.util.*;
import java.lang.reflect.*;
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 myAnnotatedElement
AnnotatedElement myAnnotatedElement
= Test. class ;
System.out.println(
"AnnotatedElement represented"
+ " by myAnnotatedElement: "
+ myAnnotatedElement.toString());
// Get the declared annotation
// using getDeclaredAnnotations() method
System.out.println(
"DeclaredAnnotation of myAnnotatedElement: "
+ Arrays.toString(
myAnnotatedElement
.getDeclaredAnnotations()));
}
catch (Exception e) {
System.out.println(e);
}
}
} |
AnnotatedElement represented by myAnnotatedElement: class Test
DeclaredAnnotation of myAnnotatedElement: [@java.lang.Deprecated()]
Example 2:
// Java program to demonstrate // getDeclaredAnnotations() method import java.util.*;
import java.lang.reflect.*;
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 myAnnotatedElement
AnnotatedElement myAnnotatedElement
= Test. class ;
System.out.println(
"AnnotatedElement represented"
+ " by myAnnotatedElement: "
+ myAnnotatedElement.toString());
// Get the declared annotation
// using getDeclaredAnnotations() method
System.out.println(
"DeclaredAnnotation of myAnnotatedElement: "
+ Arrays.toString(
myAnnotatedElement
.getDeclaredAnnotations()));
}
