      Doubly Linked List – Traversing and Search

      Traversing a Doubly Linked List A doubly linked list can be traversed either way and that too very conveniently. Inorder traversal Reverse order traversal Inorder Traversal To traverse the doubly linked list, we walk the list from the beginning, and process each element until we reach the last element. .cf { font-family: Lucida Console; font-size:

    • Random Number Vulnerability

      Random Number Vulnerability

      Computers are deterministic and are therefore predictable. Computers cannot, in and of themselves, generate truly random numbers. In the absence of outside input, computers can only create pseudo-random numbers.  In the words of John Von Neumann, “Anyone attempting to produce random numbers by purely arithmetic means is, of course, in a state of sin.” A

      Java

      Java was originally developed as an implementation of a programming language that would compile and complete its directive functions regardless of platform and language version. It was developed by James Gosling, a software developer employed by Sun Microsystems in June of 1991, whom released the first version of Java in 1995. The language is designed

      javascript:void(0)

      The javascript:void(0) error is fairly unique, in that it  is one of the few computer-based errors that can be encountered by users of any operating system. The error is thrown on web browsers with the end-user surfs to websites that are not fully compatible with the version of Internet browser being used or have a

      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

      Binary Tree – Deleting a Node

      The possibilities which may arise during deleting a node from a binary tree are as follows: Node is a terminal node: In this case, if the node is a left child of its parent, then the left pointer of its parent is set to NULL. Otherwise if the node is a right child of its

      JNI (Java Native Interface)

      The JNI (Java Native Interface) is a layer of Java that permits code executing or running in the JVM (Java Virtual Machine) to invoke and to be called by native libraries and applications written in other languages. The JNI is most commonly used with the C++, C, and Assembly programming languages. Typically, code developers will
