Using Java as a regular expression flavor, in this chapter, we will go a bit deeper and learn in detail about anchors, quantifiers, boundary matchers, all the available character classes, negated character classes, predefined character classes, and character classes escaping rules, using Java as a reference point.

We will also cover greedy versus non-greedy (lazy matching) and the change of regular expression behavior with lazy matching.
