    • Change TextBox Width with JQuery on Focus and Blur

      Let’s see how can we change the width of any HTML TextBox using JQuery on occurrence of following 2 actions: Focus and Blur. Focus is when you click anywhere inside a TextBox and Blur is when a TextBox isn’t active or focused. Prerequisite: JQuery Library should already be included in the page. Consider we have

    • 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

      Deleting an Element from a Linear 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). This tutorial covers the deletion of a node from the following three positions: At the beginning of the list At the end of the list After a given

      How to Enable Java

      The Java Virtual Machine (JVM) is a collection of software programs and data modules that forms part of the Java and Java 2 platforms. JVM works across all platforms and it alters Java bytecode into machine understandable code and executes it. It acts as a clone of a Java processor allowing Java bytecode to be

      Constructors that Allocate Memory Dynamically

      Constructors can be used to initialize member objects as well as allocate memory. This can allow an object to use only that amount of memory that is required immediately. This memory allocation at run-time is also known as dynamic memory allocation. The new operator is used for this purpose. Sample Program The program below shows

      How to Sign a Java Applet

      Java applets are designed to run in a restricted environment known as Sandbox. This confinement helps avoid malicious activities and breach of security from intentionally harmful applets. Therefore, an applet cannot access or communicate with any outside-the-sandbox resource unless granted permission by the user. The trustworthiness of an applet is showcased by signing it with

    • Disassembler


      A disassembler is a software that is able to convert an executable language into an assembly language, allowing users to view the individual commands that make a program work. A disassembler is ideal for programming applications because it can be useful when a programmer is attempting to create a similar program to one he/she already

    • Java Data Types

      Java Data Types

      Data types in the Java programming language are basically divided into two groups – primitive data types and object references. A primitive data type is a basic building block and has full built-in support. Many other languages also support composite data types, which are build on a combination of primitive data types and may or

    • Circular Queue

      Circular Queue

      The difficulty of managing front and rear in an array-based non-circular queue can be overcome if we treat the queue position with index 0 as if it comes after the last position (in our case, index 9), i.e., we treat the queue as circular. Note that we use the same array declaration of the queue.
