AnnotationFormatError in Java

java.lang.annotation.AnnotationFormatError

Thrown when the annotation parser attempts to read an annotation from a class file and determines that the annotation is malformed. This error can be thrown by the API used to read annotations reflectively.

Declaration

public class AnnotationFormatError extends Error {
    @java.io.Serial
    private static final long serialVersionUID =
-4256701562333669892L;

    public AnnotationFormatError(String message) {
        super(message);
    }

    public AnnotationFormatError(String message,
Throwable cause) {
        super(message, cause);
    }

    public AnnotationFormatError(Throwable cause) {
        super(cause);
    }
}


Methods

1. AnnotationFormatError(String message)

java.lang.annotation.AnnotationFormatError.AnnotationFormatError(String message)

This method takes one argument. This method constructs a new AnnotationFormatError with the specified detail message.

Parameters: One parameter is required for this method.

message: the detailed message.

Exceptions: NA

Approach

Java

package com.AnnotationFormatError;

import java.lang.annotation.AnnotationFormatError;

public class AnnotationFormatError1 {
    public static void main(String[] args) {

        String message = "Hello";
        AnnotationFormatError annotationFormatError =
new AnnotationFormatError(message);

        System.out.println(annotationFormatError);
    }
}

Output:

java.lang.annotation.AnnotationFormatError: Hello


2. AnnotationFormatError(Throwable cause)

java.lang.annotation.AnnotationFormatError.AnnotationFormatError(Throwable cause)

This method takes one argument. This method constructs a new AnnotationFormatError with the specified cause and a detailed message of (cause == null ? null: cause.toString()).

Parameters: One parameter is required for this method.

cause: the cause.

Exceptions: NA

Approach

Java

package com.AnnotationFormatError;

import java.lang.annotation.AnnotationFormatError;

public class AnnotationFormatError2 {
    public static void main(String[] args) {

        Throwable cause = new NullPointerException();
        AnnotationFormatError annotationFormatError =
new AnnotationFormatError(cause);

        System.out.println(annotationFormatError);
    }
}

Output:

java.lang.annotation.AnnotationFormatError: java.lang.NullPointerException


3. AnnotationFormatError(String message, Throwable cause)

java.lang.annotation.AnnotationFormatError.AnnotationFormatError(String message, Throwable cause)

This method takes two arguments. This method constructs a new AnnotationFormatError with the specified detail message and cause.

Note that the detail message associated with the cause is not automatically incorporated in this error's detail message.

Parameters: Two parameters are required for this method.

message: the detailed message.

cause: the cause.

Exceptions: NA

Approach

Java

package com.AnnotationFormatError;

import java.lang.annotation.AnnotationFormatError;

public class AnnotationFormatError3 {
    public static void main(String[] args) {

        String message = "Hello";
        Throwable cause = new NullPointerException();
        AnnotationFormatError annotationFormatError =
new AnnotationFormatError(message, cause);

        System.out.println(annotationFormatError);
    }
}

Output:

java.lang.annotation.AnnotationFormatError: Hello


Some other classes/interfaces of java.lang.annotation

Native: Indicates that a field defining a constant value may be referenced from native code.

InheritedIndicates that an annotation type is automatically inherited.

IncompleteAnnotationExceptionThrown to indicate that a program has attempted to access an element of an annotation type that was added to the annotation type definition after the annotation was compiled (or serialized). 

AnnotationFormatErrorThrown when the annotation parser attempts to read an annotation from a class file and determines that the annotation is malformed.

ElementTypeThe constants of this enumerated type provide a simple classification of the syntactic locations where annotations may appear in a Java program.

DocumentedIf the annotation @Documented is present on the declaration of an annotation type A, then any @A annotation on an element is considered part of the element's public contract.

AnnotationTypeMismatchExceptionThrown to indicate that a program has attempted to access an element of an annotation whose type has changed after the annotation was compiled.

AnnotationThe common interface is extended by all annotation types.

RepeatableThe annotation type is java.lang.annotation.Repeatable is used to indicate that the annotation type whose declaration it(meta-)annotates is repeatable.

RetentionIndicates how long annotations with the annotated type are to be retained. If no Retention annotation is present on an annotation-type declaration, the retention policy defaults to RetentionPolicy.CLASS.

RetentionPolicyAnnotation retention policy. The constants of this enumerated type describe the various policies for retaining annotations.

TargetIndicates the contexts in which an annotation type is applicable.
