About Master Java Generics in 3 Hours
Java Generics is extremely important in the Java Ecosystem. Without a deep understanding of Generics, it is now difficult to understand the Javadoc of Java Libraries and applications. We are constantly bombarded with methods which contain a confusing sequence of "?" , "? extends T" or "? super T" .
This course will take a deep look at Java Generics in a simple and quick way without any fluff.
Why is Java Generics required ?
How are Java Generics internally implemented ? And why ?
What are Parameterized Types and Raw Types ?
What are unbounded and bounded Wildcards ?
How do Arrays and Generic Types differ ?
How are Java Generics used in Collections, Java Optional and Streams ?
Along the way, we will also learn quite a bit about Java Record, Java Optional, Intersectional Types and Nested classes. There will be constant Quizzes to reinforce the concepts. All of this will make you an expert in Java Generics and how they can be used effectively while writing Java code. At the end of the course, you will be able to use Java Generics comfortably as well as fully understand the Javadoc of complex methods.
REMEMBER… I'm so confident that you'll love this course that we're offering a FULL money-back guarantee for 30 days! So it's a complete no-brainer, sign up today with ZERO risk and EVERYTHING to gain.
