Example 1

//import statements
import java.lang.annotation.Inherited;   //import  inherited

import java.lang.annotation.Retention;   //import  retention
import java.lang.annotation.RetentionPolicy;  //import  retention policy
import java.lang.reflect.Method; 
import java.lang.annotation.Annotation;  //import  annotation
import java.util.Arrays;

public class ClassgetDeclaredAnnotationbytypeExample1 {

    public static void main(String... args) {
      
        Deprecated[] dec = Class1.class.getAnnotationsByType(Deprecated.class); //getannotationbytype        System.out.println(Arrays.toString(dec)); //print statement

        Annotation1[] ann = Class1.class.getAnnotationsByType(Annotation1.class); //getannotationbytype        
        System.out.println(Arrays.toString(ann));  //print statement
    }

    @Deprecated
    public static class Class1 extends SuperClass1 {
    }

    @Annotation1
    public static class SuperClass1 {
    }

    @Retention(RetentionPolicy.RUNTIME)
    @Inherited
    private static @interface  Annotation1 {
    }
}

Output:

[@java.lang.Deprecated()]
[@ClassgetDeclaredAnnotationbytypeExample1$Annotation1()]

Example 2

//import statements...
import java.lang.annotation.Inherited;  //import inherited
import java.lang.annotation.Retention;   //import  retention
import java.lang.annotation.RetentionPolicy;  //import  retention policy
import java.lang.reflect.Method; 
import java.lang.annotation.Annotation;  //import  annotation
import java.util.Arrays;

public class ClassgetDeclaredAnnotationbytypeExample2  {

    public static void main(String... args) {
      
        Deprecated[] dec = subClass1.class.getAnnotationsByType(Deprecated.class); //getannotationbytype        
        System.out.println(Arrays.toString(dec));  //print statement

        Annotation1[] ann = subClass1.class.getAnnotationsByType(Annotation1.class); //getannotationbytype        
        System.out.println(Arrays.toString(ann));  //print statement
        
        String ann1 = subClass1.class.getCanonicalName();
          System.out.println(ann1);  //print statement
    }

    @Deprecated
    public static class subClass1 extends SuperClass1 {
    }

    @Annotation1
    public static class SuperClass1 {
    }

    @Retention(RetentionPolicy.RUNTIME)
    @Inherited
    private static @interface  Annotation1 {
    }
}

Output:

[@java.lang.Deprecated()]
[@ClassgetDeclaredAnnotationbytypeExample2$Annotation1()]
ClassgetDeclaredAnnotationbytypeExample2.subClass1
