Field getDeclaredAnnotations() method in Java With Examples
Last Updated :
24 Apr, 2023
The getDeclaredAnnotations() method of java.lang.reflect.Field is used to return annotations that are directly present on this Field object and ignores inherited annotations. If there are no annotations directly present on this element, the return value is an empty array. The caller can modify the returned array as method sent a copy of the actual object; it will have no effect on the arrays returned to other callers.
Syntax:
public Annotation[] getDeclaredAnnotations()
Parameters: This method accepts nothing.
Return: This method returns annotations directly present on this element.
Below programs illustrate getDeclaredAnnotations() method:
Program 1:
Java
import java.lang.annotation.*;
import java.lang.reflect.Field;
import java.util.Arrays;
public class GFG {
private int @SpecialNumber [] number;
public static void main(String[] args)
throws NoSuchFieldException
{
Field field
= GFG. class .getDeclaredField("number");
Annotation[] annotations
= field.getDeclaredAnnotations();
System.out.println(
Arrays
.toString(annotations));
}
@Target ({ ElementType.TYPE_USE })
@Retention (RetentionPolicy.RUNTIME)
private @interface SpecialNumber {
}
}
|
Program 2:
Java
import java.lang.annotation.Annotation;
import java.lang.reflect.Field;
import java.util.Arrays;
public class GFG {
@Deprecated
private String string
= " Welcome to GeeksForGeeks";
public static void main(String[] args)
throws NoSuchFieldException
{
Field field
= GFG. class
.getDeclaredField("string");
Annotation[] annotations
= field.getDeclaredAnnotations();
System.out.println(
Arrays
.toString(annotations));
}
}
|
Output:
[@java.lang.Deprecated()]
