Java is one of many high-level programming languages that use abstraction (reducing and factoring details) to create software for computers and many other electronic devices. Compared to low-level programming languages, high-level programming languages use a mixture of natural language (any language used by humans) and typical computer terms to create an easier to understand and simpler form of programming. Figures 1 and 2 show the difference in writing a simple program called “Hello World” in Assembly (a low-level programming language) and in Java.
Like human languages, programming languages have different levels of writing difficulty; some are easy to write, while others require extensive computer knowledge to understand. In programming, high-level languages are easier to understand, learn and write because of the use of natural language. But, as the use of natural language decreases and more words and computer statements are added, the difficulty level of language increases. This process eventually stops when we get to the lowest level of programming languages, machine language or Assembly language. This language strictly deals with solving problems using hardware, thus, requiring extensive knowledge of hardware and well as software to effectively write programs.
History of Java
Compared to other programming languages in use today, Java is fairly young. Development of a new language was taken up in 1991 by a group of Sun Microsystems engineers called the Green Team. The following year, an early version of Java, called “Oak” was introduced. After the internet had matured, in 1995 Oak was renamed to Java and the current language as is known today was officially released to the world. Ever since, there have been man...

Economic impact of Java
Since Java is so widely used in the world, its impact on the economy is large for a software language. “Sun estimates the total Java Economy to be more than (USD) $100 billion in sales annually driving an additional $110 billion in related IT spending” (Sun). Adding that up, Java’s economic impact compares to about 1.4% of the U.S. $14 trillion economy. Splitting the total value up, “The Java economy includes 2.5 billion smart cards, 800 million PCs shipped with Java, 1.85 billion Java Powered phones (source: Ovum), and over 180 telecom providers who deploy Java technology based content/services” (Sun).

Programming Koby Yumul High Line College Programming In our modern technologically advanced society, programming proves time and time again why it is the building blocks of business and continues to innovate the way we attack every situation. Even though computer programming is one of the fastest growing fields in modern time it’s also among the most competitive and demanding. There are tons of things like initially learning programming languages to help users get into the learning phase. With learning and knowing what to expect on the job.
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.

Today, the world is changing fast in many ways, and the most rapid change that is seen within our society is technology. It is imperative that businesses stay on top of what is new and how they can better their company’s outlook by presenting their information in the fastest and most reliable ways. With the two major computer programming languages of today, C++ and Java, which is better for businesses to be able to acquire such speed and consistency?
Java and Python are both popular programming languages. Each has its own strength, when it comes to programming. In my research, I have tried to elaborate the main differences and similarities, as well as some of more specific and detailed differences.
In addition to machine independence, one of the most important requirements of the language was simplicity. The committee wanted the language to be readable by laypeople, which led to the idea of using English (The Creation of COBOL,Brandel). In addition, computer manufacturers were trying to develop their commercial COBOL compilers while COBOL’s specifications were being defined (Creation of COBOL,Brandel). A complete specification was finished in just six months. That was in December 1959. In 1974, COBOL officially changed to four-digit date fields, but that change obviously didn’t catch on right away. The COBOL creators played a huge part in the famous Y2K problem because of the use of two-digit year fields they used and did not fix in time. This huge problem cost many companies millions and they say that many of these companies will not solve the problem within their own business until even as late as 2008.

In 1984, researchers at Hiroshima University started developing the layout for what would be called visual programming languages. Currently, many programmers use textual languages, which make the user produce text (one-dimensional) which is translated into one long stream of information. The goal for visual languages was to "...bridge the chasm between high level programming and the human level" (Levialdi). The researchers wanted to create languages that could display data and programs two dimensionally and have the graphical interface look much like what would soon be a web page (McIntyre). These languages are designed to be simpler while being able to construct more complicated programs than its predecessors.
Most programming languages—such as C, C++, and Fortran—use compilers, but some—such as BASIC and LISP—use interpreters. An interpreter analyzes and executes each line of source code one-by-one. Interpreters produce initial results faster than compilers, but the source code must be re-interpreted with every use and interpreted languages are usually not as sophisticated as compiled languages.
Many different types of programming languages are used to write programs for computers. The languages are called "codes". Some of the languages include C++, Visual Basic, Java, XML, Perl, HTML, and COBOL. Each of the languages differs from each other, and each is used for specific program jobs. HTML and JAVA are languages used to build web pages for the Internet. Perl and XML can produce codes that block students from getting on certain inappropriate web pages on their school server. One of the most prominent programming languages of the day would have to be C++.

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.
Computer technology not only has solved problems but also has created some, including a certain amount of culture shock as individuals attempt to deal with the new technology. A major role of computer science has been to alleviate such problems, mainly by making computer systems cheaper, faster, more reliable, easier to use.
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...
