Communication is a very important aspect in building connection between two entities. To build this connection and to connect the computer machine to human, there is a need for some connecting bridge between the two. Alike humans, computers also understand languages, but these languages are different from the language spoken and understandable by humans. To make the computer understand the instructions of the humans, we need some lines of codes written in a language understandable by computer machines. These lines of code or instructions are called computer programs. A computer program is certain lines of instructions written in a language which is understandable by the computer system. A program is written to instruct any computer system for some particular task. These lines of codes are written followed by a certain syntax and semantics and act like a solution for a problem.

To achieve success in any task, there are certain small steps that need to be followed. Some steps are rigid and some needs some kind of decision-making power. Mostly all the instructions or steps can be done by a computer system with the help of automation. The introduction of automation to the world has solved so many problems. Computer programs can be used to automate the tasks which are rigid and doesn’t require much of decision making or human involvement.

If we see these years, computers have solved issues that used to take a lot more of time. Back in time, it used to take days to communicate to a person living distant from the source but computer emails have made it a task of less than a minute. From looking up a topic in Google search to booking flight tickets to meet relatives, computers have it all. The programming world has brought every big issue to its smallest extent.

Computer programming is all about converting an algorithm to lines of instructions. It is about designing and creatively writing the instructions and make the system understand the task so that success in the task can be achieved. With the involvement of time, the range of programming languages has been increased a lot. With FORTRAN as a first programming language in 1957, now we have a long list of programming language existing in the world. These programming languages are divided into certain groups as per the purpose they serve.

C, C++, Java, Python are some of the very famous languages used by the developers. Use of computer programs automate the process and makes it more efficient and less prone to errors. Java is one of the very famous languages as it uses cover a lot of areas. Java was introduced after so many languages like FORTRAN, C++ but all these languages had few issues which were corrected with the introduction of Java.

The features of Java make it easy to understand and easy to use for developers. Java is a combination of languages introduced earlier. Java is an object-oriented language which is extracted from C++ language. It has few syntaxes of C language which is the parent language for C++ language. Combination of features from different languages makes Java unique and popular.

Java is platform independent language which is the main motivation behind the development of the language. This language doesn’t depend on the machine on which it is written. It can be written on any machine and can be run on any other machine. This portability was not present in previous languages and it was more restrictive to stick to one machine.

Apart from being portable, Java also supported web development and internet programming. The support for internet enabled developers to create dynamic web applications with the help of Applets, Servlets, swings, and other technologies.

Though Java fills up every loophole left unattended by other programming languages, still it is not developed to replace those languages. Java has its own creative and innovative features but the base of Java lies on the previously developed languages. The importance and existence of every language will be present as every language is unique and possess different concepts. It is just a matter of time that one language takes up the first place of popularity.
