    • Object


      A Java object is basically a set of data, data structures, and methods combined together to form a single entity. An object is an instance of class. Therefore, a class is said to be a blueprint of an object. Every object instantiated from a class will contain its own copy of member variables and member

      Deleting an Element from a Doubly Linked List

      To delete an element from the list, first the pointers are set properly and then the memory occupied by the node to be deleted is deallocated (freed). Deletion in the list can take place at the following positions. At the beginning of the list At the end of the list After a given element Before

    • Java vs. JavaScript

      Java vs. JavaScript

      Java and JavaScript are two different programming languages meant for different purposes and functionality. Java is an application programming language designed to write stand-alone Java programs and web applications running on the Internet. JavaScript is a client-side scripting language specifically designed to work with various web technologies, but on the client’s end. To understand the

    • Integer Overflow

      Integer Overflow

      An integer overflow, or integer wrapping, is a potential problem in a program based upon the fact that the value that can be held in a numeric datatype is limited by the data type’s size in bytes. ANSI C uses the following minimum sizes: data type size (bytes) char 1 short 2 int 2 long

    • Type Conversion – Class to Basic Type

      Type Conversion – Class to Basic Type

      The constructor handles the task of converting basic types to class types very well. But you cannot use constructors for converting class types to basic data types. Instead, you can define an overloaded casting operator that can be used to convert a class data type into a basic data type. The general form of an

    • Type Conversion – Class to Class

      Type Conversion – Class to Class

      Now that we have understood how to convert basic data types to class types and vice-versa, it is time to learn how to convert objects of one class type to another class type. The conversion between objects of different classes can be done using either a one-argument constructor or a conversion function. The choice depends

    • Java Servlet

      Java Servlet

      A Java Servlet is the Java technology used to extend and improve Web server functionality. Servlets are able to provide a platform independent way to build web-based applications founded upon components without the performance limitations found with comparable CGI applications. Since Java Servlets are platform and server independent, they can be deployed across the full

      How to Debug Java

      The ability to debug any modern programming language is a critical skill for programmers of all skill levels. Learning how to debug Java helps developers discover the causes of logic and non-trivial syntax errors that prevent proper execution of Java programs. The ability to step-through a Java program using a debugging environment provided by updated

    • Breadth First Search Algorithm

      Breadth First Search Algorithm

      A breadth first search traversal method, visits all the successors of a visited node before visiting any successor of any of its child nodes. This is a contradiction to depth first traversal method; which visits the successor of a visited node before visiting any of its brothers, i.e., children of the same parent. A depth

      Traversing and Searching a Linear Linked List

      Traversing a list A linear list can be traversed in two ways In order traversal Reverse order traversal In order Traversal To traverse the linear linked list, we walk the list using the pointers, and process each element until we reach the last element. .cf { font-family: Lucida Console; font-size: 9pt; color: black; background: white;
