Override

AI-generated Key Takeaways

• @Override is an annotation used to indicate that a method is intended to override a method in its supertype.

• The compiler generates an error if the annotated method doesn't override a supertype method or have an override-equivalent signature to a public method in Object.

• @Override helps ensure that methods are correctly overridden, promoting code clarity and preventing accidental errors.

• This annotation inherits methods like annotationType(), equals(), hashCode(), and toString() from the Annotation interface.

public abstract @interface Override implements Annotation

Indicates that a method declaration is intended to override a method declaration in a supertype. If a method is annotated with this annotation type compilers are required to generate an error message unless at least one of the following conditions hold:

• The method does override or implement a method declared in a supertype.
• The method has a signature that is override-equivalent to that of any public method declared in {@linkplain Object}.

Inherited Method Summary

From interface java.lang.annotation.Annotation

abstract Class<? extends Annotation>	annotationType() Returns the annotation type of this annotation.
abstract boolean	equals(Object obj) Returns true if the specified object represents an annotation that is logically equivalent to this one.
abstract int	hashCode() Returns the hash code of this annotation, as defined below: The hash code of an annotation is the sum of the hash codes of its members (including those with default values), as defined below: The hash code of an annotation member is (127 times the hash code of the member-name as computed by String.hashCode()) XOR the hash code of the member-value, as defined below: The hash code of a member-value depends on its type: The hash code of a primitive value v is equal to WrapperType.valueOf(v).hashCode(), where WrapperType is the wrapper type corresponding to the primitive type of v (Byte, Character, Double, Float, Integer, Long, Short, or Boolean).
abstract String	toString() Returns a string representation of this annotation.
