Several of us might be familiar with the clear () API in Java collections framework. In this post, let’s discuss what is the purpose of this clear() API? What is the performance impact of using this API? What happens under the JVM when this API is invoked?

java.lang.String#intern() is an interesting function in Java. When used at the right place, it has potential to reduce overall memory consumption of your application by eliminating duplicate strings in your application. To learn how intern() function works, you may refer to this blog. In this post let’s discuss the performance impact of using java.lang.String#intern() function in your application.

There are a good number of articles that articulate functional differences between HashMap, HashTable and ConcurrentHashMap. This post compares the performance behavior of these data structures through practical examples. If you don’t have patience to read the entire post, here is bottom line: When you confront with the decision of whether to use HashMap or HashTable or ConcurrentHashMap, you can consider using ConcurrentHashMap since it’s thread-safe implementation, without compromise in performance.

When we launch applications, we specify the initial memory size and maximum memory size. For the applications that run on JVM (Java Virtual Machine), initial and maximum memory size is specified through ‘-Xms’ and ‘-Xmx’ arguments. If Java applications are running on containers, it’s specified through ‘-XX: InitialRAMPercentage’ and ‘-XX: MaxRAMPercentage’ arguments. Most enterprises set the initial memory size to a lower value than the maximum memory size. As opposed to this commonly accepted practice, setting the initial memory size the same as the maximum memory size has certain ‘cool’ advantages. Let’s discuss them in this post.
