A Brief Introduction to Java

The Silicon Valley is brimming with people who are passionate about computers and programming. One of the most widely used programming languages in that community is Java. Naturally, if you are not familiar with programming languages, you may not entirely know what Java is. Java is an object oriented programming language that was introduced in the late 1990s. At the time of its introduction, it was the only object oriented programming language available. How is that significant? You will find out about it later in the article.

History of Java

Before Java was introduced, C was the most widely used programming language. But like any other language, C programming had its limitations. With the advancement of technology, there was a need of complex programs that could simplify tasks. However, C programming was very simple and tedious at the same time. If you wanted to write a complex program, the program would run to thousands of lines of code.

Identifying this, James Gosling and his team of engineers at Sun Microsystems, started a project called ‘Oak’. The aim of this project was to develop a programming language that simplified the task of writing long, tedious programs. Originally, they focused on developing small applications that could be run on web browsers (internet was still in its early stages of development). But at the end of it, they came up with a programming language that had a lot more advantages than the team had imagined.

Advantages of Object Oriented Programming

Take the example of two programs, one that adds an array of numbers and another that multiplies them. The approach here is to fetch the numbers from its memory location, add it or multiply with the next number, store the result in another memory location, fetch the next number, multiply or add with the result stored from the previous operation, and continue till all the numbers are exhausted.

Here, you notice that almost all the steps of both the programs are the same. The only difference is in the arithmetic operation that is carried out. In programming that is not object oriented, you have to write two different programs which essentially will have only one line different, the line that performs the arithmetic operation. However, in object oriented programming, you can create objects for all the redundant tasks. So, the number of lines of code is reduced and that is exactly what Java does.

Other Advantages of Java

Java is designed in such a way that it is very easy to learn. The syntax, keywords, and other nuances are simple and easy to understand. Another big advantage of Java is that it is independent of the system it is being used on. It doesn’t matter if it’s a Windows, UNIX, Mac or any other system. Java works in the same way. Security is also built into the programming language. So, even if you don’t implement any security protocols, your application is reasonably safe. Above all, Java is very reliable and flexible. The programming is robust and you can rest assured that the application will remain stable and not crash.

Where Java was winning

There are a lot of industries that prefer Java based applications over software to download and install and these are virtually all industries with a gaming environment that is simple and where users switch accordingly. So for a simple browser game nobody wants to download and instlal every single game he wants to try out. Imagine you had to download every single online slot game. For most players this would be just too much effort. These kind of industries are interested in promoting their products online with Java based applets.
