Encapsulation<\/strong><\/h3>\n\n\n\n

Binding data and putting it together is called encapsulation.<\/p>\n\n\n\n

The process of implementing abstraction is called encapsulation.<\/p>\n\n\n\n

Class is the basic unit of encapsulation.<\/p>\n\n\n\n

Abstraction always describes outer behavior of object and encapsulation describes inner behavior of object.<\/p>\n\n\n\n

Abstraction<\/strong><\/h3>\n\n\n\n

Process of getting essential things from an object is called abstraction.<\/p>\n\n\n\n

Polymorphism<\/strong><\/h3>\n\n\n\n

Polymorphism is\u00a0the ability of any data to be processed in more than one form<\/strong>. The word itself indicates the meaning as poly means many and morphism means types.<\/p>\n\n\n\n

Hierarchy<\/strong><\/h3>\n\n\n\n

The level or ranking order of abstraction is called hierarchy.
There are 4 types of hierarchy<\/p>\n\n\n\n

  1. Composition: has-a relationship<\/li>
  2. Inheritance: is-a relationship<\/li>
  3. Dependency: use-a relationship<\/li>
  4. Instantiation: creates-a relationship<\/li><\/ol>\n\n\n\n

    Inheritance<\/strong> <\/h4>\n\n\n\n

    A journey from generalization to specialization is called inheritance.Its main purpose is to achieve re-usability<\/strong>.<\/p>\n\n\n\n

    \n\n\n\n

    3 minor pillars of OOPS<\/h2>\n\n\n\n
    1. Typing<\/li>
    2. Persistence<\/li>
    3. Concurrency<\/li><\/ol>\n\n\n\n

      Typing<\/strong> (polymorphism)<\/h3>\n\n\n\n

      one interface having many behaviors is called polymorphism.<\/p>\n\n\n\n

      e.g. board can be used for writing or screen projection.<\/p>\n\n\n\n

      USB ports can be used for a webcam or headphone or mouse.<\/p>\n\n\n\n

      There are two types of polymorphism<\/p>\n\n\n\n

      1. compile time polymorphism<\/li>
      2. runtime polymorphism<\/li><\/ol>\n\n\n\n

        Compile Time Polymorphism<\/strong><\/h3>\n\n\n\n

        when the function gets called at compile time is called as compile time polymorphism also called as static binding \/ static polymorphism \/ early binding \/ weak typing \/ false polymorphism.<\/p>\n\n\n\n

        Run Time Polymorphism<\/strong><\/h3>\n\n\n\n

        when a call to the function gets resolved at runtime is called runtime polymorphism. It is also called dynamic binding \/ dynamic polymorphism \/ strong typing \/ true polymorphism.<\/p>\n\n\n\n

        • Compile time polymorphism can be achieved by operator overloading or function overloading.<\/li>
        • Runtime polymorphism can be achieved by function overriding.<\/li><\/ul>\n\n\n\n

          Persistence<\/h3>\n\n\n\n

          It refers to saving data (usually to a disk) for future access.<\/p>\n\n\n\n

          Concurrency<\/h3>\n\n\n\n

          Concurrency<\/strong> refers to the potentially parallel execution of parts of a computation. In a concurrent computation, the components of a program may be executed sequentially, or they may be executed in parallel.
          In Java concurrency is achieved by implementing Multithreading.<\/p>\n\n\n\n
