Module 11 · Practical Language & Runtime

Beyond the 1Z0-830 exam

This is the first Part B module — necessary developer/SDET knowledge that the exam doesn't test. Annotations, reflection, and regex are the foundation of the testing frameworks (JUnit, Mockito) and data tooling you'll use daily, so they come first in the beyond-exam track.

Everyday language and runtime features beyond the exam's core: annotations (and how frameworks read them), reflection (and its costs), and regular expressions (and their traps).

Lessons

#	Lesson	What it covers
01	Annotations	Built-ins, custom @interface, @Retention/@Target, runtime processing.
02	Reflection (basics)	Class, members, instantiation/invocation, accessibility, costs.
03	Regular Expressions	Pattern/Matcher, String methods, groups, greedy vs lazy.
