The short answer is that it doesn’t. They are not related at all, except by name. However, they are both very popular and useful languages to their own merit, so we’ll take an abstract look at them both.
Quick differences :
|Statically typed (variable datatype needs to be specified beforehand)||Dynamically typed (variable type is resolved directly during runtime)|
|Class based (functionality is stored in a way such that it belongs specifically to the instance from which it is accessed)||Prototype based (functionality is simply reduced to a property template that executes whenever required)|
|All non block statements should end with a semicolon.||Semicolon is optional in most circumstances.|
|Java has an implicit
If you’re new to programming and the table above didn’t make much sense to you, don’t worry. The table just contains some technical details that’ll help you to separate how one language works from another in your mind while actually writing code. Since you’re reading a blog post that’s basically trying to pitch one language versus another, I’m going to assume that you might be more interested in the difference between these two languages in terms of application and use case.
Every environment has its own set of characteristic features that a programmer needs to keep in mind when developing in it, and I believe that the act of “putting yourself in the respective mindset” of that environment brings out efficient code in the end. What I’m trying to say is that if you try to eat an orange like you would eat an apple, you might end up successful in your goal, but the overall experience will be messy and unsatisfactory. Hence, becoming thoroughly familiar with the frame of mind you need to be in for your environment first is important.
The Java mindset
A Java developer will have a concrete idea of the structure of every class in his project, like a map of properties and functions, so he knows how each instance will interact with each other. When you need to use a lot of object oriented logic, including inheriting from other classes, polymorphism, and modularization by separating functionality into their own classes, then you’re going to be passing instances around a lot. That’s how you know that you need a language like Java for your task.
Also useful to note is that Java has its own core set of libraries, and virtual machine platform where code is compiled.
Where to use Java :
- For standalone apps - If you just want to create a command line or GUI application on the go, to run natively, Java is a good bet. In fact, you can’t make Android apps without Java.
- Browser Applets - Although Java applets are becoming rarer and old, sometimes they are used to extend the functionality of the limited power that web browsers have over your system.
- Embedded devices - Java was originally written with portability in mind, such that it can easily be made to run in embedded projects due to its scalability.
- Drivers - Java-like languages like C or C++ are often used to develop software to make hardware work, although you might want to use a language different from Java for this purpose.
