Reflection in Java

Explore the Java class object by using getClass and Class.forName to obtain type objects, inspect super classes, wrappers, interfaces, primitives, and declared or enclosing classes through reflection.

Explore Java reflection by inspecting and invoking methods at runtime: obtain Method objects with getDeclaredMethod and getMethods, inspect names with getName, and invoke methods on objects.

Explore java reflection with the Field class to access, print, and modify specific class fields using get declared fields, get fields, and Field.set on an object.

Use reflection to obtain a class object's declared constructors with getDeclaredConstructors, iterate these constructor objects, and print each constructor's name for the Rectangle class.

Explore how reflection bypasses private and package-private access to fields and methods, using setAccessible, getDeclaredField, and getDeclaredMethod on a rectangle example to read and modify width and area.

Access solutions for each coding exercise, and request additional explanations; we will create a short video clip with further exploration.
