You can resolve java.lang.UnsatisfiedLinkError: lwjgl64.dll : Access Denied error in Minecraft by disabling your anti-virus and run. Later you can whitelist the lwjgl64.dll, so that your anti-virus will not block it again. I have talked about java.lang.UnsatisfiedLinkError couple of times on this blog e.g. here and here. But, today I am going to show you one more real life example of java.lang.UnsatisfiedLinkError, which is more interesting. We'll also learn and how to deal with that. This problem is related to Minecraft, one of the most popular game written in Java. Precisely, we are going to solve the "Exception in thread "main" java.lang.UnsatisfiedLinkError: lwjgl64.dll: Access denied" error.
You can reverse an ArrayList in place in Java by using the same algorithm we have used to reverse an array in place in Java. If you have already solved that problem then It's a no-brainer because ArrayList is nothing but a dynamic array, which can resize itself. All elements of an array are stored in the internal array itself. By the way, if you need to reverse an ArrayList then you should be using the Collections.reverse() method provided by Java Collection framework. It's generic method, so you can not only reverse an ArrayList but also Vector, LinkedList, CopyOnWriteArrayList, or any other List implementation. Though, worth noting is that this method internally uses a ListIterator for reversing the list, which might not be as efficient as our algorithm.
If you are an author of an internal, proprietary Java library or an external open source library, or you are one of those lucky developers who ship Java application by yourself then you should follow these best practices while naming your JAR files. These best practices are a result of the practical experience of using hundreds of Java library and application. Following these best practices will help in better management of JAR files. It's part of my other best practices articles e.g. best practices while naming variable, writing comments, overriding methods, muli-threading, JDBC, and best practices while dealing with passwords. If you are interested in learning more best practices, you can always search those articles on this blog.
