Garbage Collection in Java | What is GC and How it Works in JAVA | Part One

Garbage Collection is the process of reclaiming the runtime unused memory by destroying the unused objects.

It is a part of the Java Virtual Machine (JVM) and helps you maintain free memory in your system for running Java applications.

In languages like C and C++, the programmer is responsible for both the creation and destruction of objects. Sometimes, the programmer may forget to destroy useless objects, and the memory allocated to them is not released. The used memory of the system keeps on growing and eventually there is no memory left in the system to allocate. Such applications suffer from "memory leaks".

A standard Garbage Collection implementation involves three phases:
1. Mark
2. Sweep
3. Compact

Java Garbage Collectors implement a generational garbage collection strategy that categorizes objects by age.

In this video, I'll talk about Garbage Collection in Java and cover the following topics:
1. What is Garbage Collection
2. How Garbage Collection works in Java
3. How to dereference objects in Java
4. What are the different heap generations
5. What is minor and major garbage collection

After searching for so long, finally found this in depth analysis of garbage collection. Really appreciate your efforts!!

[barboza]

These videos are literally helpfull.please keep uploading more videos on java

[gauravpareek]

Without background music it would have better...

[himanshumendapara]

Please make more videos about java. I loved it!!!

[vishnusingh]

Awesome brother!
You just earned yourself a subscriber!
If it's not asking too much, can you please make some videos on usage of design patters with industry standard code and Low Level Design?

Would be really helpful for all as there's very little content available on the same.

[rushmadz]

Background music is very disturbing. It was hard to gather the content, but it was a good content. Please don't add any background music since this is a tutorial which educates people/students. Thanks. Good Luck with your future videos.

Bhaii
U r teaching style is very simple and useful.
Please make a playlist of full course java.
Love from kendrapada ❤️
Big fan after seeing your podcast
In E-learning bridge 😊

[MegaSriku]

The explanation is lucid. Without bg music it could be even better. Please add more videos on distributed systems, scalable application design.

[dibyadas]

Nice explanation sir👍👍👍
Sir make videos for placement
For those who are at 3rd year know only some basic coding

[IamRajMayank]

Sound can be more clear. Request you to make it more noiseless.

[nonyabiness]

I think youre gonna be the reason Ill pass, my midterm. I couldnt make sense of how GB chose what it was gonna delete until this video <3

[TheAIGadgetGuru]
