Introduction
Java was developed by a team led by James Gosling at Sun Microsystems. Originally called Oak, it was designed in 1991 for use in embedded consumer electronic appliances. In 1995, renamed Java, it was redesigned for developing Internet applications.
Java is a full-featured, general-purpose programming language that is capable of developing robust mission-critical applications. Today, it is used not only for Web programming, but also for developing standalone applications across platforms on servers, desktops, and mobile devices. It was used to develop the code to communicate with and control the robotic rover that rolled on Mars. Many companies that once considered Java to be more hype than substance are now using it to create

Note
In addition to the two comment styles, // and /*, Java supports comments of a special type, referred to as javadoc comments. javadoc comments begin with /** and end with */. They are used for documenting classes, data, and methods. They can be extracted into an HTML file using JDK's javadoc command.
1.10.2. Reserved Words
Reserved words, or keywords, are words that have a specific meaning to the compiler and cannot be used for other purposes in the program. For example, when the compiler sees the word class, it understands that the word after class is the name for the class. Other reserved words in Listing 1.1 are public, static, and void. Their use will be introduced later in the book.
Tip
Because Java is case-sensitive, public is a reserved word, but Public is not. Nonetheless, for clarity and readability, it would be best to avoid using reserved words in other forms.
1.10.3. Modifiers
Java uses certain reserved words called modifiers that specify the properties of the data, methods, and classes and how they can be used. Examples of modifiers are public and static. Other modifiers are private, final, abstract, and protected. A public datum, method, or class can be accessed by other classes. A private datum or method cannot be accessed by other classes.
1.10.4. Statements
A statement represents an action or a sequence of actions. The statement System.out.println("Welcome to Java!"); in the program in Listing 1.1 is a statement to
Java was designed at the Sun Microsystems in 1992 by James Gosling and the Green Team, these individuals designed an operating system with an independent processor, object oriented programming language which is the leading interactive environment used on the web. This open source software are used on a variety of devices, music players, automobiles, cells, and smart phones. Java has changed the computer environment because the developers designed it to operate on any computing devices regardless of the specific microprocessor or the operating system it is installed on (Laudon, 2014).
Java programming is widely used programming language that has a wide verity of application, such as; Mobile application, Enterprise Application, Desktop applications, etc. Java program was created by Sun Microsystems in early 1990s. It was created to solve the problem of connecting many household machines together. Java is class based and object oriented programming language. Java programming is secure, fast and reliable. It’s free and created for the general purpose.
Java is a simple object oriented computer programming language. Java is developed by James Gosling at sun Microsystems. At first java is called as “OAK” after it is named as “Green” later on it is named as java. Java is similar to C/C++ style. It is popular for “Write once, Run Anywhere” (WORA). It released in 1995 as “Java 1.0”. Unlike C and C++, Java can run in any operating system or in any computer. Java allowed accessibility to network also. We can use java applets for web pages which increased the popularity of java. Java programs take more memory than C++ programs, but java programs
Programming languages are vast and diverse in their numbers. These different languages use fundamental styles of programming called programming paradigms. These programming paradigms layout the particular design approach that a program will use to solve a problem or achieve an objective. Of the many different types of programming paradigms, some of the more distinguished ones are procedural, functional, logical, and object orientated programming. Recently the object orientated languages have been rising in popularity due to their ability to easily implement large programs. There are many different object orientated programming languages (OOPLs), among them are C#, Java, Ruby, and Python. This essay will compare and contrast two of these languages: Python and Java.
Programming Language is artificial language aims to conveys the instructions to the device and especially computer device. Also we can be used to setting up programs to control the behavior of the device or to express to algorithm. Programming Language divided to high-level language it means that it is close to the language that it understood by humans such as: C and Java. On other hand there is low-level language as Assembly language: is the second generation of programming languages programmer writes instructions using symbolic instruction codes and it is close to the machine language is the first generation
Java is a programming language first released by Sun Microsystems in 1995. There is a lot of devices and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific per computers, cell phones to the Internet, Java is everywhere!
In earlier times, before object oriented was introduced, the languages that used is so uncomfortable and not familiar to developers. A normal person cannot understand what that was coded. The language that time used makes lots of errors, bugs, misunderstands… between developing programs.
25. The public access specifier for an field indicates that the field may not be accessed by statements outside the class.
Security controls for the network system involves the creation of access and use for each user or user group. The control is used to "restrict a list of possible actions down to the allowed actions. For example, encryption can be used to restrict access to data, application controls to restrict processing via authentication, and DRM storage to prevent unauthorized accesses." (Securosis, 2012) The necessary controls are determined by "first listing out
Java is a object-oriented programming language .It is originally developed by James Gosling at Sun Microsystems and released in 1995.The programs in java are platform independent that means the programs can be run on any operating system with any type of processor as long as the java interpreter is available on the system.
Java as a programming language is one that was designed in a time when the distribution of information was rapidly increasing. Its original purpose was to be used in a home entertainment controller for the television, however it was much too advanced for the industry (The History of Java Technology), and so java moved on to a much more capable, and growing internet. Java’s uses aren’t just restricted to the internet though, Java is/was produced to be easily distributed and implemented among many platforms. Java was produced with a set of goals in mind. One of its most noteworthy and successful goals was to be portable/ cross platform. Java owes a good amount of its success to its object oriented core, as well as being built upon its familiarity with the c languages among other things. Java like all programming languages are judged based on their writability, readability, reliability and overall cost.

A compiler is a computer program that translates a computer program written in one computer language (source language) into an equivalent program written in another computer language (target language). Interpreter is similar to compiler but interpreter compiles line by line while compiler compiles as a whole. Examples: C, C++, BASIC, COBAL, etc. The C programming language has been used for last few decades for almost all the applications. Recently, the C++ with Object Oriented
