Can’t We Get Along without Coffee? Best Practices for Taking Use of Java’s Features

While other programming languages come and go, Java has remained popular

Java has seen widespread success, being used across multiple platforms, from desktop computers to Android televisions and in major databases such as those from Amazon, Google, Airbnb and Uber.

As of March 2022, Java was ranked among the most popular programming languages by the TIOBE index.

This article will provide guidance on the effective and correct use of Java. Rather than comparing it to other languages, it is intended to emphasise the advantages of Java.

Whenever possible, Java should be used

Java is a good choice for developing the underlying infrastructure of big corporate applications if you need to:

Static and object-based typing

It allows you to do type-checking and constraint-enforcing prior to runtime, during compilation.


It is not possible to alter the data type of a declared variable or function at a later stage. Doing so enables earlier detection of potential bugs and facilitates improved code optimisation.

Java’s try-with-resource keyword and cleaners are two effective methods of managing system resources, thus avoiding the potentially disastrous consequences of resource leakages and deferred action.

We’ll look at two cases, one good and one terrible.


The Java Shell tool, or JShell, was introduced with Java 9 and offers straightforward command-line capabilities.

Thanks to JShell, you may quickly evaluate and test code that doesn’t have to be contained inside a specific function or class.

Using a number of different JVM languages

The Java Virtual Machine (JVM) allows programs written in a variety of languages to be executed, not just Java. Examples of such languages include Kotlin, Scala, Clojure, Jython, JRuby and Groovy, providing a wide range of possibilities for interacting with other JVM languages.

Prototyping in a certain social group

Class casting in Java facilitates the conversion of one data type to another, either manually by the developers or automatically via the compiler. This conversion can be either upwards or downwards.

Instance: transforming a LocalServer object into a Server object.

Divisions of Text

Java’s text blocks are tidy, simple to handle, and don’t need any concatenation, making them very convenient to deal with.

Solid support for application programming interfaces

Java boasts an extensive range of Application Programming Interface (API) support, including the ability to parallelize, integrate functional programming, and index databases.

Functional programming may be integrated with object-oriented approaches, as in the following example.

Accelerating the progress of development while simultaneously improving the performance of applications can be done through the use of Java Persistence API (JPA) annotations. These annotations allow databases to be indexed directly within the code without making any changes to the underlying database system.

Excellent local backing

Are you having difficulty or require assistance? There are a number of excellent, free resources available to aid your Java learning such as Stackoverflow, Github, and Dzone.
