Remove Duplicate Elements from a Java List
In this post, we’ll walk through multiple ways to remove duplicates from a Java List, using: Depending on your use case and preference, decide which approach is the best fit. 1. Set approach The simpler and easier way to remove duplicates is to convert the list into a Set, since sets don’t allow duplicates. If…
How to Partition a List in Java – Different Approaches
Partitioning a list in Java is a common task, especially when dealing with large datasets, batching, or displaying data in pages. The idea is simple: split a big list into smaller chunks of a specified size. Let us look at a few clean and effective ways to partition a list in Java using: Each method…
Java Threads : Usage and Examples
Threads are used to perform tasks in parallel. They allow concurrent operations within an application. It is a lightweight process that runs independently but shares the same resources as the CPU and memory of the parent process. The availability of threads concept gives rise to multithreading, a technique that enables multiple threads to be active…
Java SE 24: New Features, Code Examples, and Performance Improvements Explained
1. Pattern Matching for Primitive Types in instanceof and switch (JEP 488) Previously, Java’s pattern matching worked only with objects, requiring explicit casting when dealing with primitives. Java SE 24 extends this functionality to primitive types, allowing more concise and readable code in instanceof checks and switch statements. Example: Using instanceof with primitives Before this…
