Training Java Courses-
The Java platform at its core, is a way of computing that is based on the power of networks and the idea that the same software should run on different kinds of computers, consumer gadgets and other devices. The architecture-neutral nature of Java technology is extremely important in a networked world where one cannot predict what kind of devices our partners, suppliers and employees may use to connect to you.

Put simply, Java technology based software works just about everywhere from the smallest devices to super computers, Java technology components are not affected by the kind of computer, phone, TV or operating system they run on. They work on any kind of compatible device that supports Java platform. It is an object-oriented language that enables you to create real world applications.

  2. Adding a new key-value pair

    1) Calculate hashcode for the key
    2) Calculate position hash % (arrayLength-1)) where element should be placed(bucket number)
    To find the bucket number HashMap uses hashcode , hash and indexFor functions.

    Please check this blog for a demo of what I have mentioned above. Please correct me if my understanding is wrong somewhere.

  23. Hi Dinesh,
    i have one doubt in HttpServlet class is abstract class but HttpServelt their is no abstract methods but why declare abstract class.
    plz tell me..

    ReplyDelete
  24. because its implementation provide by server.

    ReplyDelete
  25. in java abstract class we can create constructer .but we can not create the object of that class .why?

    ReplyDelete
  26. because abstract class we always extends with other class then we create object of its subclass it automatically call constructor of super class that is why we have to mention construction in abstract class as well.

  35. Note: The code shown here for what put() actually does is from Java 7. It's changed in Java 8; if there's a collision, the Entry objects may be stored as a linked list, but they may also be stored as a binary search tree, which improves performance when buckets get too big.
