Java Programming - An Overview

Introduction to Java Programming

As we all know that Java programming is a general purpose programming language much like Python and JavaScript. Along with general purpose programming language, Java is also an object oriented programming language. It is a platform or it is a kind of code which can be used in any system that has Java Virtual Machine in it.

Origin - Java Programming

Java was initially developed by a team of experts at Sun Microsystems and it was released in the year 1995. The main objective of Java developers was to create a language that can run on any system. So with the intentions clear, the designers were already contemplating a world in which there was code that will run even on the refrigerator or a toaster - which is now called as the internet of things.

One of the major selling point for Java was “write once, use anywhere,” so in simple words, you can write the code once and then it can be used to compile on any device. Now this tells us that Java is also a complier language. Ironically, Java did not gain the popularity for this reason, instead the developers could gain advantage of something else that came out in the mid-1990s I.e., the world wide web(www).

Java had this feature where you could write something called as the applets, which is a very small programme that could run on the web browser and this came up when the www was gaining a lot of popularity. Java used that wave and became extremely popular and successful. So, this allowed a lot of web application to be written in Java though this wasn’t in the developers mind until that point of time.

Source for creating Java Programming

The creators of this Java programming language were greatly influenced by already existing programming languages such as C and C++ which is called as the basic programming language of all, it is the base before learning any programming language. This is the reason that Java has a lot of similarity with C and C++. The developers used this languages has an example to come up with certain things such as: how to create, to do things, features not to be included etc.

Statistically Typed VS Dynamically Typed

Dynamically Typed: Java is definitely a statistically typed language, whereas Ruby, Python and JavaScript are dynamically typed. In a dynamically typed programming languages such as Python, Ruby etc, we can declare the variables without actually saying what it is and what type of data it is. When I say variable, it can be anything: a sentence, a number etc. The mistakes committed can be found out only once the code is executed and not at the time of typing the code.

Statistically Typed: When we are to deal with statistically typed programming languages like Java, we have to properly declare what each variable does. This also means that a statistically typed programming languages has a much more structure to it. The mistakes committed in this type of languages are only known at the time of building the code itself.

How is Java different from JavaScript

Technically, there’s no relation between these two programming languages. JavaScript was originally developed by the Netscape company in the mid-90s and they named it has LiveScript. After doing so, nobody really started using it hence the netscape company had to rename it and then this name came up as Java was already picking up, this idea of naming it as JavaScript actually worked as people started to use it and JavaScript became popular.

Like we already saw, technically there’s no relation between these two, they just are named similarly. The only similarity between these two is the syntax that is used and these are the replica of C programming language. Hence usually it is said that, knowing Java makes things easier at the time of programming with JavaScript and vice versa.

Where all can we use Java?

One very good thing with Java is that it’s meant to be a very general purpose programming language, it’s used used in lots of different environment. Java is explicitly intended to run in any kind of environment, hence you can run it on Linux, Windows, Mac, or even your cell phones, etc.

Advantages & Disadvantages of Java?

Advantages:

1. Java is very simple

2. Java is an object oriented programming language

3. Java is cheap and economical to maintain

4. It also provides an efficient memory allocation strategy.

5. Java is a platform independent programming language i.e., WORA (Write Once Run Anywhere)

6. Java supports portability feature

7. Java also acts as a distributed language.

Disadvantages

1. Java lacks the back-up facility

2. Java is a very slow and has a poor performance

3. Java requires a significant storage space

4. Java requires a lot of coding for a very simple one liner outcome

5. We cannot expect a beautiful outcome, look or a design using Java Programming

These are some of the advantages and disadvantages of Java programming.

Alternatives to Java Programming

Alternatives to Java that are most analogous and used for similar purposes apart from Java are C#, .Net etc.

Conclusion

Java has been consistently holding the top spot in various research organisations among all the other programming languages. Though new programming languages are coming up day-by-day, java does not loose its spot. Just like other programming languages, Java to has its hooks and crooks but still it is managing to rule over the other programming languages for as long as 20years.
