Java is commonly used and also high level object-oriented programming language which has wide verity of applications and lets the programmers to develop applications for web, mobile and desktop. Below are the principles, characteristics and features of Programming in Java:
- Java is Simple:
It is a very simple language since it is easy to learn and create by using the best features from other languages mostly like C and C++. When an individual have the basic about object oriented programming concept it is easy to learn Java. Java also provides automatic memory management by development environment and eliminates pointers that offer programmer the error free development environment.
- Java is Platform Independent:
Java Provide the facility of cross-plateform programs by collecting in intermediate code known as “bytecode” which only can be read on any systems which have Java Virtual Machine (JVM). Furthermore, Java provides the facility to "Write once -Run any where" or known as plateform independent. There is no single language that is idle to this feature but however Java closer to this features.
- Java is Object-oriented:
Java is a fully object oriented language because object is at the outer most level of data structure in java. It also support the characteristics of the OOPs. Every single thing in Java is preserved as objects to which procedures are applied. The whole thing in java is object including the primitive data types can also be converted into object through the wrapper class.
- Java is Distributed :
Program developers can call function on protocols like HTTP and FTP. They can get access to the files from whichever remote machine on the internet rather than writing codes on the local system.
- Java is Secur...

- Development and maintenance costs
To consider the cost to develop a project or to maintain could be important to embarking the software development. Few of the languages have reputation to cut the prices and time in order to make it quick and easy to develop and maintain the program.
- Expandability
Several software programs have to support thousands of simultaneous users. There are systems that are written for interactive website that needed to support a huge number of users with no crashing. But some other languages scale or expand than the others. These features normally support large systems that considered a strong choice for a project.
The internet works on the basis that some computers act as ‘servers’. These computers offer services for other computers that are accessing or requesting information, these are known as ‘clients’. The term “server” may refer to both the hardware and software (the entire computer system) or just the software that performs the service. For example, Web server may refer to the Web server software in a computer that also runs other applications or it may refer to the computer system dedicated only to the Web server applicant. For example, a large Web site could have several dedicated Web servers or one very large Web server.
It also includes pair programming where two developers work on the same pc, while one typing and other offered advice. This improved programs productivity and decrease error.
Also, the cost of software programming, vast libraries of stored data, and teaching un-educated computer users in all countries around the world, but be an expansive process.
The Ada language is the result of the most extensive and most expensive language design effort ever undertaken. The United States Department of Defense (DoD) was concerned in the 1970¡¦s by the number of different programming languages being used for its projects, some of which were proprietary and/or obsolete. Up until 1974, half of the applications at the DoD were embedded systems. An embedded system is one where the computer hardware is embedded in the device it controls. More than 450 programming languages were used to implement different DoD projects, and none of them were standardized. As a result of this, software was rarely reused. For these reasons, the Army, Navy, and Air Force proposed to develop a high-level language for embedded systems (The Ada Programming Language). In 1975 the Higher Order Language Working Group (HOLWG) was formed with the intent of reducing this number by finding or creating a programming language generally suitable for the department's requirements.
Project managers must take cost estimates seriously if they want to complete software projects within budget constraints. After developing a good resource requirements list, project managers and their software development teams must develop several estimates of the costs for these resources. There are several different tools and techniques available for accomplishing good cost estimation.
The programming language C++ can be used in many ways. It has exploded into the gaming community allowing PC game programmers to have access to a stabile, yet powerful, programming language, utilizing as little code as possible. It has also been used in other commercial software, such as word processors, audio players, screen savers, and other computer desktop tools.
It has a huge community of developers who constantly work to upgrade features. Python is a dynamic language and supports different programming styles including object-oriented, aspect-oriented, functional and imperative. One of the best features of the language is easy and enhanced memory management. Essentially employed as a scripting language, Python offers a great level of functionality. While it can be used as a standalone program, you can also integrate third party tools and customize its functionality.
Object-orientated programming is methodology which is organized around objects and not actions. The perspective that this approach takes is that it is easier to compare objects. Object-orientated programming can be used in conjunction with UML, and within Object-orientated programming and there are various different methods. Object-orientated programming can be defined as constructing a model of a real world through combining data and actions.
Even though Java is a language that is object-oriented which is similar to C++, it is a simpler version eliminating features of language that can cause common errors while programming. The files of Java are compiled into a format known as byte code (these files have a .class extension), which can later be executed by an interpreter. The compiled code can run on most computers because of the interpreter and the runtime environments; these are known as a Java Virtual Machines.
Traditionally, one program is written and execute on a single computer and on a single processor. But it can take more time to solve a problem if it is large enough.
Computer programming can as well be defined as a process that leads from an original formulation of a computer problem to execute problems. Computer programming is also referred to as programming. It encompasses other activities such as understanding, analysis and generally solving problems that result in algorithm, verifying the algorithm requirements and coding algorithm in a target program language. The program also involves the implementation of the build system and managing derived artifacts like computer programs machine codes. Most often, the algorithm is represented in human-parseable languages such as Java, Python, Smalltalk among others.
Python is a programming language made easy to code and read. Python is what is called an interpreted language, which the computer runs right away. This allows the programmer to make changes in the code quickly and efficiently with as few lines of code as possible. It is derived from C, but is an easier to read. It uses whitespace to delimit code, such as spaces or tabs to organize data. At the end of the lines, neither semicolons nor curly braces are necessary, making it an easy language to read. Fullscreen games can be made with Python, if one manages to access the correct libraries.
Java Script allows you to respond to a user's input in the form of text, buttons selected, or mouse clicks, and can generate a response to the user's computer. Java Script originated from within the labs of Netscape Communications Corporation in 1994. It was invented so a computing language could build web pages and applications more effectively. When it first appeared it was thought that it was a new form of C, but later turned out to be this wonderful new language called JavaScript.
Pascal programming language was designed in 1968, and published in 1970. It is a small and efficient language intended to encourage good programming practices using structured programming and data structuring. Pascal was developed by Niklaus Wirth. The language was named in honor of the French mathematician and philosopher Blaise Pascal. In 1641, Pascal created the first arithmetical machine. Some say it was the first computer. Wirth improved the instrument eight years later. In 1650, Pascal left geometry and physics, and started his focus towards religious studies. A generation of students used Pascal as an introduction language in undergraduate courses. Types of Pascal have also frequently been used for everything from research projects to PC games. Niklaus Wirth reports that a first attempt to merge it in Fortran in 1969 was unsuccessful because of Fortran's lack of complex data structures. The second attempt was developed in the Pascal language itself and was operational by mid-1970. A generation of students used Pascal as an introductory language in undergraduate courses. Pascal, in its original form, is a Procedural language and includes the traditional like control structures with reserved words such as IF, THEN, ELSE, WHILE, FOR, and so on. However, Pascal has many data structuring and other ideas which were not included in the original, like type definitions, records, pointers, enumerations, and sets. The earliest computers were programmed in machine code. This type of programming is time consuming and error prone, as well as very difficult to change and understand. Programming is a time-consuming a process. More advanced languages were developed to resolve this problem. High level languages include a set of instruction...
