      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 Decompiler

      Java Decompiler

      A Java decompiler is a special type of decompiler which takes a class file as input and produces Java source code as output. De-compilation is exactly the reverse process of compilation. However, decompilation will never produce an exact replica of the source code but does give back a major percentage. This is because quite a bit

    • Display Messages using Flashdata in CodeIgniter

      Flashdata is a functionality in the CodeIgniter framework that lets you make required data available for the next server request.

      It is quite important to know which version of Java is installed on your computer, especially if you are developing applications and software on the Java platform. Using an outdated version of Java may hinder your Java development or even render web pages inappropriately in your browser. Below are few straightforward ways to check which

    • Address Calculation Sort

      In this method, a function fn() is applied to each key. The result of this function determines into which of the several sub-files the record is to be placed. The function should have the property that x <= y, fn (x) <= fn (y). Such a function is called order preserving. Thus all of the

    • 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
