Learn Reflection with Java

Reflection is a powerful feature in Java that can be used to expand the capabilities of a program, or to examine a class, method, or object at runtime, even if you don’t know its name. In this course from Pearson, get started with the basics, then learn how reflection works with the more modern language features such as sealed classes and records, as well as how arrays can be manipulated and created via reflection. Along the way, explore the purpose of MethodHandles and VarHandles to find out when and how to use them both like a pro.

Learning objectives
Inspect a class and find methods, fields, and constructors at runtime.
Call methods and change fields, even if they are private.
Write more general code that can be reused in many different contexts.
Understand VarHandles and MethodHandles and know when to use them.
Inspect sealed classes and records via reflection.
