  3. Java collections framework - Wikipedia

    en.wikipedia.org/wiki/Java_collections_framework

    Collection implementations in pre-JDK 1.2 versions of the Java platform included few data structure classes, but did not contain a collections framework. [4] The standard methods for grouping Java objects were via the array, the Vector, and the Hashtable classes, which unfortunately were not easy to extend, and did not implement a standard member interface.

  4. 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.

  5. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    The class defines the data format or type (including member variables and their types) and available procedures (class methods or member functions) for a given type or class of object. Objects are created by calling a special type of method in the class known as a constructor. Classes may inherit from other classes, so they are arranged in a ...

    In the Java virtual machine, internal type signatures are used to identify methods and classes at the level of the virtual machine code. Example: The method String String. substring (int, int) is represented in bytecode as Ljava / lang / String. substring (II) Ljava / lang / String;. The signature of the main method looks like this: [2]

  8. Wrapper function - Wikipedia

    en.wikipedia.org/wiki/Wrapper_function

    Wrapper functions simplify writing computer programs. For example, the MouseAdapter and similar classes in the Java AWT library demonstrate this. [2] They are useful in the development of applications that use third-party library functions. A wrapper can be written for each of the third party functions and used in the native application.

  9. Virtual function - Wikipedia

    en.wikipedia.org/wiki/Virtual_function

    In object-oriented programming, when a derived class inherits from a base class, an object of the derived class may be referred to via a pointer or reference of the base class type instead of the derived class type. If there are base class methods overridden by the derived class, the method actually called by such a reference or pointer can be ...
