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 …
The programming language called PHP is quickly rising to be one of the most preferred web browser programming languages due to its user-friendliness, efficiency, and user control. PHP allows a user to describe specific functions within the code in order to drastically control the way a web browser displays and organizes information. A user is …
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. …
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 does not directly support constants. However, a static final variable is effectively a constant. The static modifier causes the variable to be available without loading an instance of the class where it is defined. The final modifier causes the variable to be unchangeable. Ex: public static final int FOUNDING_YEAR = 2001; Naming Standards for …
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 …
SDLC (Systems Development Life Cycle) is the process of creating or modifying existing systems and the models and methodologies that are used in the process. In the fields of software engineering and information systems, SDLC denotes a framework of methodologies aimed at the creation of an information/software system, i.e. the software development process. SDLC covers …
The JDK (Java Development Kit) most commonly refers to an implementation of the Java SE or Java 2 SE. It can also refer to Java EE or Java ME implementations released by Oracle in the form of binary products targeted to Java developers that work on the Windows, Mac OS X, Linux, or Solaris platforms. …
The term algorithm is used in a variety of fields, including mathematics, computer programming, and linguistics. Its most well-accepted definition is something that consists of a finite list of instructions (which are well defined) that can be used to accomplish a task. Basically, when an algorithm is given some initial state, it will use the …
In a doubly linked list, also called a two-way list, each node is divided into three parts: The first part, called the previous pointer field, contains the address of the preceding element in the list. The second part contains the information of the list. The third part, called the next pointer field, contains the address …
