      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

    • Deleting an Element from a Heap

      Deleting an Element from a Heap

      Deleting an Element from the Heap Deletion always occurs at the root of the heap. If we delete the root element it creates a hole or vacant space at the root position. Because the heap must be complete, we fill the hole with the last element of the heap. Although the heap becomes complete, i.e.

    • SQL Injection Attack / Vulnerability

      SQL Injection Attack / Vulnerability

      A SQL injection vulnerability can occur when a poorly-written program uses user-provided data in a database query without first validating the input. This is most-often found within web pages with dynamic content. There are some excellent tutorials and descriptive articles on this subject, as well as many vulnerability postings for different applications from full-disclosure websites.

    • Depth First Search Algorithm

      Depth First Search Algorithm

      A DFS algorithm, as the name implies, is used to search deeper in the graph, whenever possible. The edges are explored, out of the most recently discovered vertex v that still has unexplored edges leaving it. When all of v's edges have been explored, the search backtracks to explore edges leaving the vertex from which

    • Java Package

      Java Package

      A Java package is a set of classes which are grouped together. This grouping helps to organize Java classes and codevent multiple Java classes with the same name. Using Java Packages To use a package in your Java source code, you must either import the package or use the fully qualified class name each time

      Hex Editor

      A hex editor is a program edits compiled programs and binary data files. These editors are called hex editors because they most often present data in hexadecimal format. Hexadecimal is used because it is easier for most humans than working in binary. In addition, hexadecimal is frequently useful because computers tend to work with 8-bit
