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:
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 {
AnnotatedElement myAnnotatedElement
= Test. class ;
System.out.println(
"AnnotatedElement represented"
+ " by myAnnotatedElement: "
+ myAnnotatedElement.toString());
System.out.println(
"DeclaredAnnotation of myAnnotatedElement: "
+ Arrays.toString(
myAnnotatedElement
.getDeclaredAnnotations()));
}
catch (Exception e) {
System.out.println(e);
}
}
}
|
Output:
AnnotatedElement represented by myAnnotatedElement: class Test
DeclaredAnnotation of myAnnotatedElement: [@java.lang.Deprecated()]
Example 2:
import java.util.*;
import java.lang.reflect.*;
import java.lang.annotation.*;
@Retention (RetentionPolicy.RUNTIME)
@interface DeclaredAnnotation {
public String key();
public String value();
}
@DeclaredAnnotation (key = "GFG" , value = "GeeksForGeeks" )
public class Test {
public Object obj;
public static void main(String[] args)
throws ClassNotFoundException
{
AnnotatedElement myAnnotatedElement
= Test. class ;
System.out.println(
"AnnotatedElement represented"
+ " by myAnnotatedElement: "
+ myAnnotatedElement.toString());
System.out.println(
"DeclaredAnnotation of myAnnotatedElement: "
+ Arrays.toString(
myAnnotatedElement
.getDeclaredAnnotations()));
}
}
|
Output:
AnnotatedElement represented by myAnnotatedElement: class Test
DeclaredAnnotation of myAnnotatedElement: [@DeclaredAnnotation(key=GFG, value=GeeksForGeeks)]
