2. At present, programmers use Java for developing a variety of desktop, web, and mobile applications. Each new version of Java also comes with new features to meet the emerging trends in software development. But the developers still have to explore ways to keep the Java code organized, clean, and maintainable. Often mistakes committed by Java programmers directly affect the functionality of the software and quality of its source code. The Java programming mistakes made by individual developers differ. But both beginners and experienced programmers end up making a number of common mistakes. That is why; it becomes essential for Java programmers to identify and avoid some common mistakes.

3. N Not ot C Con onv veying eying Pr Prec ecise ise M Mea ean ning ing of of C Cod ode e El Elemen ements ts While writing Java code, programmers create several new classes, methods, variables, and packages. But they often forget to name the code elements appropriately. Often the name of a code element does not convey their meaning or usage precisely. Hence, the developers find it daunting to modify or maintain the code in future. The Java programmers can easily make the code maintainable by following proper naming conventions and choose names that describe the code elements clearly.

4. Using Regular Expressions Many programmers use regular expressions frequently in Java code. They forget the adverse impact of regular expressions on the performance of the Java application. It is always important for programmers to use regular expressions in computation-intensive code sections. If a programmer wants to use regular expressions in computation-intensive code sections, he must prevent the regular expressions from being executed frequently by caching the pattern reference.

5. Ignoring the Amount of Memory Consumed by Various Methods Often Java programmers ignore the amount of memory consumed by individual methods. They affect the performance of the application adversely by calling the memory expensive methods directly. When they call an expensive method directly, the program requires additional time to calculate value and deliver results. The developers can easily keep the a??lica?i??’? performance intact by calling the cache instead of the method.
