How to Remove a Key, Value, or Entry from an HashMap in Java 8 - Example Tutorial

In the last article, I have shown how to remove key/value pairs from a map in Java-based upon some conditions like remove all entries where values are greater than some values. I have told you that you must use the Iterator's remove() method for removing mapping while iteration to avoid ConcurrentModificationException, but that's not required anymore in Java 8. From JDK 8 onwards, you can selectively remove mapping without iterating over Map. The JDK 8 API has added several new methods to existing interfaces e.g. java.util.Collection, java.util.Map, Comparator, etc because the interface can now contain concrete methods in the form of static and default methods.

What is happens-before in Java Concurrency? An example

A couple of days ago, one of my readers messaged me on LinkedIn about a Java interview question he has recently faced - what is the happens-before relationship in Java concurrency? What is the benefit of it, and how exactly it works? He kind of has some ideas about that its related to the Java Memory Model and provides some sort of visibility guaranteed but couldn't explain with conviction to his interviewer, particularly with a code example and was a bit disappointed. He then asked me if I can write an article about it. I said you should have read the Java concurrency in Practice book before the interview, that would have helped, but nonetheless, I liked the idea to just provide a quick overview of what is the happens-before relationship between threads in Java.

For a long time, there wasn't a popular technology to build GUI application in Java but then Java introduces Java FX, a more modern GUI development API to reclaim the lost ground. While I don't see Java FX has reached the height which Swing has touched or is challenging C# for desktop GUI development, it's growing nicely and it is now the standard Java technology for GUI development, particularly for developing cross-platform GUI application.

3 Design Patterns and Best Practices you can Learn From Spring Framework

There is no doubt that the Spring Framework is one of the most popular Java frameworks and makes it really easy to create real-world, enterprise-grade Java applications easy by providing features like dependency injection and inversion of control. But, to be honest, Spring is much more than just another DI and IOC framework. It goes one more level to simplify many Java APIs like JDBC, JMS, Java Mail, etc by providing a useful layer of abstraction.
