Regular Expressions (RegEx):Unleash the potential of regular expressions in Java to search, match, and manipulate text patterns within your applications, enhancing data validation and manipulation. Multi-threading and Concurrency:Delve into the world of concurrent programming, enabling your Java application...
In thefirstarticle we learned about Lambdas, functional interfaces and method references introduced in Java 8. In thepreviousarticle we saw default methods in interfaces and their inheritance rules. In this article we look at the new default methods added in the Collections hierarchy. Many of the ...
In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list sorted in ascending order. This is a basic way to sort a list in Jav...
