  2. Method (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Method_(computer_programming)

    A method in Java programming sets the behavior of a class object. For example, an object can send an area message to another object and the appropriate formula is invoked whether the receiving object is a rectangle , circle , triangle , etc.

  3. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    Instance methods – belong to individual objects, and have access to instance variables for the specific object they are called on, inputs, and class variables Depending on the definition of the language, subclasses may or may not be able to override the methods defined by superclasses.

  4. clone (Java method) - Wikipedia

    en.wikipedia.org/wiki/Clone_(Java_method)

    clone() is a method in the Java programming language for object duplication. In Java, objects are manipulated through reference variables, and there is no operator for copying an object—the assignment operator duplicates the reference, not the object. The clone() method provides this missing functionality.

  5. Method overriding - Wikipedia

    en.wikipedia.org/wiki/Method_overriding

    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]

  6. Object copying - Wikipedia

    en.wikipedia.org/wiki/Object_copying

    (Methods in Java are always pass by value, however, it is the value of the reference variable that is being passed.) [11] The Java Virtual Machine manages garbage collection so that objects are cleaned up after they are no longer reachable. There is no automatic way to copy any given object in Java.

  7. Inheritance (object-oriented programming) - Wikipedia

    en.wikipedia.org/wiki/Inheritance_(object...

    Some languages require that method be specifically declared as virtual (e.g. C++), and in others, all methods are virtual (e.g. Java). An invocation of a non-virtual method will always be statically dispatched (i.e. the address of the function call is determined at compile-time).

  8. Primitive wrapper class in Java - Wikipedia

    en.wikipedia.org/.../Primitive_wrapper_class_in_Java

    Primitive wrapper classes are not the same thing as primitive types. Whereas variables, for example, can be declared in Java as data types double, short, int, etc., the primitive wrapper classes create instantiated objects and methods that inherit but hide the primitive data types, not like variables that are assigned the data type values.

  9. Class (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Class_(computer_programming)

    The object methods include access to the object state (via an implicit or explicit parameter that references the object) whereas class methods do not. If the language supports inheritance , a class can be defined based on another class with all of its state and behavior plus additional state and behavior that further specializes the class.
