Java has been around for more than 20 years, yet it remains as one of the world’s most forward-thinking programming languages. But what makes Java so appealing that at least three billion gadgets rely on it in one way or another?
Optimal Memory Management
Memory is a big deal in computer systems. A device that cannot handle a ton of memory will suffer in terms of performance. In the world of business, this can lead to reduced profits and even severe losses. But Java uses what’s called a heap, which is the area where all the objects are located in.
Running the Java virtual machine (JVM) automatically produces a heap. And while your app is running, the size of this heap can change. Once this heap is filled, ‘garbage’ is collected — these are the objects your app doesn’t currently need. These are then removed to make way for new objects in the heap.
Furthermore, the heap can be classified into two sections: the young and the old space. The former is also known as the nursey, and it’s where new objects are temporarily stored. Any objects that have been in the young space for quite some time are taken to the second section during garbage collection.
All in all, Java keeps your app running smoothly with its automated memory management. This gives you more time to focus on more complex tasks rather than handling the constant entry and exit of objects.
Developing applications can be tough, but scaling it is an entirely different matter. Once you gain more clients and your customer base reaches an all-time high, you would need to improve your app. It needs more storage, memory, and all the configurations to allow more services being used by more people at the same time.
Thanks to Java, developers don’t need to spend much of their time making your app compatible with newer devices. Once the code is written, it should run on any gadget that has JVM. The IT department can then prioritize other user concerns such as how to set up VPN on Android or delete cookies on obscure web browsers.
It’s reassuring to know that you won’t always have to create new versions of your app. Combine this with its superb memory management, and it’s easier to understand why many companies still use Java.
