One of the most popular programming languages used in the world software development is Java. This programming language is both easy to use and extremely powerful.
Using proper error logging exceptions can help you detect and fix errors within your code. Ignoring the issues a recently developed program has will only lead to less user engagement over time. (source: https://www.loggly.com/blog/logging-exceptions-in-java/ )
Read below to find out about some of the most common Java programming errors you need to avoid.
1. Ignoring Existing Java Libraries
Some newcomers to the world of software and app development try to reinvent the wheel when it comes to using Java programming. Before you spend copious amounts of time writing out long lines of code, you need to check out some of the Java libraries available online.
With the help of these libraries are updated regularly, which means the code contained with them is error free and easy to use. Experienced programmers realize the value of these Java libraries and use them to make their job easier.
2. Issues With Memory Leaks
One of the best features that Java has is automatic memory management. While this memory management feature is helpful, it can also create problems for new developers when it comes to figuring out how memory is used in their application.
Java memory leaks are common and come in a variety of forms. One of the most common causes of these memory leaks is everlasting object references. The garbage collector built into Java will not be able to remove objects if you still have references to them in your code. If all of your static fields are classified as GC roots, they will linger even if you try to get rid of them.
3. Don’t Ignore Exceptions
Leaving exceptions unhandled may be tempting, but it should be avoided at all cost. There is always a reason for exceptions, which is why you need to figure out what the problem is and fix it.
Neglecting to handle these exceptions will usually lead to problems with your program over time. Luckily, there are a number of programs you can use to find exceptions and diagnose them. Utilizing the power of these tools will make the exception troubleshooting process much easier.
If your program creates a number of short-lived objects, you will probably experience issues with excessive garbage allocation. The garbage collector is designed to work continuously to remove any unneeded objects from your program’s memory. Having an excessive amount of garbage allocation will slow your program down and make it hard to operate.
Becoming a top-notch Java programmer will require a lot of trial and error. By taking notice of the common Java errors mentioned in this article, you can avoid problems with the apps and software programs you develop.
