There are methods that a subclass cannot override. For example, in Java, a method that is declared final in the super class cannot be overridden. Methods that are declared private or static cannot be overridden either because they are implicitly final. It is also impossible for a class that is declared final to become a super class. [9]
C# have records which provide immutability and equality testing. [1] The record is sealed to prevent inheritance. [2] It overrides the built-in ToString() method. [3]This example implementation includes a static method which can be used to initialize a new instance with a randomly generated globally unique identifier (GUID).
In Java, this will mean that the method in the derived class will implicitly override the method in the base class, even though that may not be the intent of the designers of either class. To mitigate this, C# requires that if a method is intended to override an inherited method, the override keyword must be specified. Otherwise, the method ...
One of the most important capabilities that a method provides is method overriding - the same name (e.g., area) can be used for multiple different kinds of classes. This allows the sending objects to invoke behaviors and to delegate the implementation of those behaviors to the receiving object. A method in Java programming sets the behavior of ...
Illustration of method overriding. Many object-oriented programming languages permit a class or object to replace the implementation of an aspect—typically a behavior—that it has inherited. This process is called overriding. Overriding introduces a complication: which version of the behavior does an instance of the inherited class use—the ...
Java, C++ (Since C++11) and D allow inheritance or overriding a class method to be prohibited by labeling a declaration of a class or method, respectively, with the keyword "final". In the book Effective Java, author Joshua Bloch writes (in item 17) that programmers should "Design and document for inheritance or else prohibit it".

The public keyword is used in the declaration of a class, method, or field; public classes, methods, and fields can be accessed by the members of any class. [17] return Used to finish the execution of a method. It can be followed by a value required by the method definition that is returned to the caller. short
