The Java Virtual Machine (JVM) employs a technique called Just-In-Time (JIT) compilation to optimize the performance of your Java applications. Here’s a breakdown of how it works: Traditional Interpretation: JIT Compilation in Action: Benefits...
Java developers often encounter the terms “JIT” (Just-In-Time) and “PGO” (Profile-Guided Optimization) when discussing performance optimization techniques. Both approaches aim to improve the efficiency of Java applications, but they operate in distinct ways. JIT...
In the ever-evolving world of software development, the need to interact with native code from Java applications frequently arises. This interaction allows leveraging existing C/C++ libraries or accessing hardware capabilities unavailable within the Java...
Understanding how virtual threads, introduced in Java 16, interact with underlying OS threads is crucial for optimizing I/O bound tasks. This code snippet demonstrates creating two virtual threads that perform calculations and make slow...
While physical CPU cores provide the foundation for parallelism, traditional operating system threads can become resource-intensive for applications with a high number of concurrent tasks. Enter virtual threads in Java 16, a lightweight alternative...
This example compares two approaches for converting an image to grayscale: a traditional loop-based method and a vectorized approach using the Java Vector API. Scenario: We have a 2D array image representing the image...
The Vector API was introduced in Java 16 as an incubator module, but it wasn’t until Java 17 that it became a standard feature. This API allows developers to leverage Single Instruction Multiple Data...
In JDK 21, pattern matching was introduced in Java. Here’s an example demonstrating pattern matching in a switch statement using JDK 21.In this example, we have a switch statement that matches the given country...
Logging frameworks like Log4j provide more sophisticated and flexible ways to manage and output log messages compared to simply using System.out.println() (or System.out in Java). Here are several reasons why using a logging framework...
The ForkJoin framework is a part of the Java Concurrency API introduced in Java 7. It provides a high-level way to perform parallel computations that can take advantage of multiple processors or cores available...
