Follow These Java Best Practices for Ultimate App Performance

Java is a programming language that has evolved the most. From being birthed as an embedded devices' programming language, Java has evolved into a language that can be utilized to build robust and secure codes for all platforms. Java's impeccable versatility, robustness, and scalability render it suitable for a diverse range of applications. And, thus it is so that Java is the most popular programming language even to this day, throughout the world.

However, even when we have it good, we want it better. Such is the human nature. And, hire java developers have always been exploring how Java can be exploited for performance benefits on a number of platforms. With IoT and Data Analytics and Machine Learning, it has become increasingly important, to regard security and process perfection, as the highest aim.

Java application

Here are some of the best practices that Java developers can follow to improve the overall performance of their Java application development-

• Pair Programming – This methodology of writing code takes us back to our school days when one of us would write the code, and the other partner would read the code and think about the potential issues that could spring up from it. This is done with the help of two developers who share the infrastructure. While the focus of one of the developers is on writing the code, the other developer focuses on finding and analyzing the code for possible performance issues. This step makes sure that the code is improved upon just as it is being written. There are people who love to undertake pair programming for the simplicity and the effectiveness of the method.

• Premature Optimization – It is advisable to delay optimization until it is necessary. Premature optimization takes up a lot of time, and more often than not, developers need to do it again. Only after developers can prove that an optimization process is necessary, should the process be implemented. Premature optimization also makes the code hard to maintain and read, introducing unnecessary complexities in it. Why should you spend a lot of time, improving on the non-critical aspects of your application?

• Test the performance – By creating a performance test suite for your application, you can make sure there are no loopholes left in the application, and that no new ones have crept in. Building a performance test suite and running it on the application before and after executing it, can give you a fair idea of the window of improvement you have achieved. These test runs make sure that no other aspects of the app were impacted when you make a performance upgrade to your app.

• Follow Conventions – With coding conventions, Java developers can be sure that they have developed the best possible code for their application. Coding conventions help save the maintenance time and costs. These guidelines are prepared by the developers and carry the recommended style of programming and the methods for each individual aspect of the code. Everything including the file organization, indentation, spacing, comments, etc., is included in this document. This makes the code readable by another programmer because history has it that no project was solely started and finished by a single team. With a detailed convention guide, you can improve the performance of your application.

Reviewing the code is the next obvious step, to ensure that the performance of the application you are developing remains top-notch. With these guidelines and tips in mind, effective improvements can be made to the performance of any application.
