Learn Reflection with Java

Video description

A well-rounded Java programmer should know reflection, when to use it, and more importantly, when not to use it.

Overview:

Reflection is a powerful Java feature that can be used to expand the capabilities of a program, to examine the class or object internals at runtime.

Some key points covered in this course:

• Save programming time by writing dynamic solutions to reoccurring problems.
• Learn how dynamic coding via reflection affects Java performance and correctness.
• A well-rounded Java programmer should know reflection, when to use it, and more importantly, when not to use it.

Skill Level:

Beginner to Intermediate

Learn How To:

• Inspect a class and find methods, fields, and constructors at runtime
• Call methods, 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
• Know how sealed classes and records can be inspected via reflection

Course Requirement:

• Students should be very familiar with Java 11, understanding data structures, object orientation, recursion and modern Java syntax.
• Prior experience with reflection is a bonus, but not necessary.

Who Should Take This Course:

Profile: Java programmers, programmers of other languages new to Java.
