Java Generics | Practical Java Development

An excerpt from my new course titled "Master Practical Java Development".
In this course, you'll learn everything you need to know about the Java Programming Language and become a confident industry-ready core Java developer and get certified as a Java professional!
=========================================
➡️ Learn MORE:
=========================================
- Latest updates include Lambdas and Streams with Java 9 Features.
- Course Last Updated: 2023!

➡️ Welcome to The Complete Java Certification Course
- This course is designed to help you master the most in-demand and critical components for becoming a Core Java developer.
- Especially if you're going for a job interview or have a Java Project that needs your best performance.
- This course assumes no prior java experience so prior Java so it will take you from zero to hero!

➡️ COURSE INCLUDES:
Java Basics
Working with Java Data Types
Using Operators and Decision Constructs
Creating and Using Arrays
Using Loop Constructs
Working with Methods and Encapsulation
OOP Basics
Working with Inheritance
Java Class Design
Handling Exceptions
Working with Selected classes from the Java API
Advanced Class Design
Generics and Collections
Lambda Built-In Functional Interfaces
Java Stream API
Exceptions and Assertions
Use Java SE 8 Date/Time API
Java I/O Fundamentals
Java File I/O (NIO.2)
Concurrency
Building Database Applications with JDBC

➡️ The topics covered also include:
- Object Orientation which I think is not stressed enough in other Java courses so I've got a special focus on that throughout the lectures.
- You'll get plenty of practice writing classes and interfaces as well as countless methods with loops and if-else statements, exception handling and file processing as well as how to debug software using Eclipse.
- You'll also be mastering the collections framework and diving deep into java generics.
- You'll learn all there is to know about multi-threading and the JDBC API for working with a MySQL database.
- There are also practical projects scattered throughout the course so that you can practice the concepts as you learn them. For example one of the projects is related to a car dealership management system and another assignment involves processing files with stock market data. So as you can see I tried to keep the projects professional and industry relevant rather than cloning a game like flappy bird.

- I want this course to be the ultimate go-to resource for anyone that's looking to become a core Java programmer so I intend on adding more content to this course based on new technologies and student feedback.
- The content is Java 9 ready which means I'll show you how to upgrade to the latest version of Java which is version 9 and I'll teach you how to configure Eclipse to work with both Java 8 as well as version 9.
- I'm confident that you'll enjoy this course at least as much if not more than my other popular Java courses, but as always you've got a 30-day money-back guarantee no questions asked! Check out the preview lectures and join today!

Amazing! My lecturer at uni spent 3h explaining generics and i was like "saaayy whaaat now..?". Watched this and it all made sense! Feels like magic, dude!

[PrecisionY]

There is only one small issue with the code. You never added objects to mySet2. You added all the objects in mySet1. It still does not make any difference in the result, but I just wanted to clarify that for people who are still learning.
Great tutorial and explanation btw. It helped me a lot! :D

[nvfpv]

Bro this explanation was so good I remembered how much I love learning

[KG-vorg]

One of the best video explaining the Genric concept in short and smart pattern...

[fifaham]

The best tutorial on Youtube - thank you.

[gomathapa]

Finally got to see a precise explanation. Thank you for sharing your knowledge.

[Waaade]

you are master of explaining. Great, step by step explained, clear voice. Perfect quality. Just. hey WOW ! Gratz !

[MetallicDETHmaiden]

Best explanation I have found on generics.

[lovetocode]

Awesome explanation.... 👍👍 I nowhere found better explanation about generics than here..

[tedthebed]

The syntax of declaring the generic in the method signature is confusing. Thanks for your video. Now it makes much more sense.

[JustMastermind]

Did no one saw, that he didn't change mySet1 to mySet2 at 23:13?

[nadeenrawashdeh]

impossible how much pretty this lesson is thank you very much🤩🤩

[What-srpk]

Hi you are so good at explaining
although there is one thing that I feel like you should think about
and that is if you created specific playlists for specific subjects
you really is the only one who brought up this generics topic which is very important on youtube properly so thank you

[venkatk]

Excellent. Thank you for the video. It's crystal clear now

[alexj]

Thank you for the explanation. Very well articulated.

[minpor]

you have one mistake! You created mySet2 and no one information was added

[Ahmedq]

love all of your tutorials... Thanks for these awesome ones

This is great. I've been watching a lot of Java generics videos this weekend to plug any little holes anywhere in my knowledge, as it is one of those topics more people think they fully understand than actually do. One comment, altho it is quite legal to have type names in lowercase letters in Java, it is not a great practice, it is rather easy to be confused. So if you don't use T and U for your parameterized types, I'd at least use I1 and I2 rather than i1 and i2. Again, not illegal, but not standard Java.

lot of information that i was looking for
