AnnotatedElement getAnnotations() method in Java with Examples
  • Last Updated : 03 Jan, 2020

The getAnnotations() method of java.lang.AnnotatedElement class is used to get the annotations present in the class implementing this interface. The method returns an array of annotations present.

Syntax:

public Annotation[] getAnnotations()

Parameter: This method does not accepts any parameter.

Return Value: This method returns an array of annotations present.

Below programs demonstrate the getAnnotations() method.



Example 1:




// Java program to demonstrate
// getAnnotations() method
  
import java.lang.reflect.*;
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 myAnnotatedElement
            AnnotatedElement myAnnotatedElement
                = Test.class;
  
            System.out.println(
                "AnnotatedElement represented"
                + " by myAnnotatedElement: "
                + myAnnotatedElement.toString());
  
            // Get the annotation
            // using getAnnotations() method
            System.out.println(
                "Annotation of myAnnotatedElement: "
                + Arrays.toString(
                      myAnnotatedElement
                          .getAnnotations()));
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
Output:

AnnotatedElement represented by myAnnotatedElement: class Test
Annotation of myAnnotatedElement: [@java.lang.Deprecated()]

Example 2:




// Java program to demonstrate
// getAnnotations() method
  
import java.lang.reflect.*;
import java.util.*;
import java.lang.annotation.*;
  
// create a custom Annotation
@Retention(RetentionPolicy.RUNTIME)
@interface Annotation {
  
    // This annotation has two attributes.
    public String key();
  
    public String value();
}
  
// call Annotation for method
// and pass values for annotation
@Annotation(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 annotation
        // using getAnnotations() method
        System.out.println(
            "Annotation of myAnnotatedElement: "
            + Arrays.toString(
                  myAnnotatedElement
                      .getAnnotations()));
    }
}
Output:

AnnotatedElement represented by myAnnotatedElement: class Test
Annotation of myAnnotatedElement: [@Annotation(key=GFG, value=GeeksForGeeks)]
