Enhancing Code Performance with Java finalize and gc Methods | Java Garbage Collection

Welcome to our Java tutorial series! In this video, we'll be exploring two important aspects of Java's memory management system: the `finalize()` method and the Garbage Collector (GC). These features play a crucial role in Java's automatic memory management process, helping developers ensure proper cleanup of resources and efficient memory usage in Java applications.

In this tutorial, we'll cover the following key points:

1. Understanding the `finalize()` method: We'll provide a comprehensive explanation of the `finalize()` method, which is a method defined in the `Object` class and invoked by the Garbage Collector before reclaiming an object's memory. You'll learn how to override the `finalize()` method in your classes to perform resource cleanup and other necessary operations before an object is garbage collected.

2. Exploring the Garbage Collector (GC): We'll delve into the workings of the Garbage Collector, which is responsible for reclaiming memory occupied by objects that are no longer in use by the application. You'll understand the different generations of memory managed by the Garbage Collector, the various garbage collection algorithms used by the JVM, and how to monitor and tune the Garbage Collector's behavior for optimal performance.

3. Best practices and examples: We'll discuss best practices for using the `finalize()` method and working with the Garbage Collector in Java applications. You'll see practical examples illustrating how to properly implement the `finalize()` method and how to analyze Garbage Collector logs to diagnose memory-related issues and optimize memory usage.

Whether you're a beginner learning Java programming or an experienced developer looking to deepen your understanding of memory management in Java, this tutorial is designed to provide you with valuable insights into the `finalize()` method and the Garbage Collector.

sir here i have one confusion is that you was saying that finalize() we used when object created without new keyword but here objected by new keyword and we call here also finalize()

Might as well mention here, the .finalize() method was deprecated finally in Java 9 after years of people complaining about it being neither reliable nor safe.
