The famous quote for Java “Write Once, run everywhere” is the major reason behind the popularity and wide usage of JAVA programming language in the market. Most of the developer’s choice is JAVA for a number of reasons. First thing, it avoids the complexities of other languages like C and C++. Second thing, Java has OOPS concepts. Next, Java has a smooth learning curve so that developers can easily identify. With the all these features, getting certification through Java Training in Chennai is a better choice if you are planning your career in software field. In spite of being easy to learn there are some mistakes arise during the development process by the developers. Let us see some most common mistakes that are to be avoided. Avoiding these mistakes will not only save your time but also make the code as bug-free. Here are The Most Common Mistakes Java Developers can avoid
- Avoiding “Break” keyword in switch case
Missing a break keyword might look like a small error, but if you miss one “break” sometimes it will be undiscovered even in the production which will be an embarrassing moment after you find out.
- Forgetting to check existing libraries
There are numerous pre-defined libraries available in Java which is regularly updated and also free to use. Before start writing a code from scratch, spend some time to check existing library that will save your precious time. Use logging libraries, network libraries etc.,
- Not Freeing Resources
Java developers especially freshers make sure to free the resources once they completed the process using a network or file connection that is opened by a program. If it is not done, the computer will consume more resources indefinitely.
- Generating memory Leaks
Even though Java allocates and frees up memory automatically, still some issues arise if there are any unused objects which are not used anymore. The reason is sometimes Garbage collection unable to remove objects that have own reference. Due to the cause circular dependencies, cross-referring objects are not removed by Garbage collector. One should take action to reduce memory leaks.
- Ignoring Exception Handling
Exceptions are thrown to clear the error, have the practice to manage all those thrown exceptions. Addressing the issues is the best practice ever by the freshers as well as experienced developers.
These above are The Most Common Mistakes Java Developers can avoid. Java Training will assist beginners on how to handle the errors tactically since the individual training on practical session will mold a person to the next level. J2EE Training in Chennai enables the learners to become a skillful developer in creating a user-friendly application.
