Can someone list comprehensive list the pros and cons of using regular expressions in Java programing?

---

Pro: when regular expressions do what you need.

Con: when they don't.

Other than that, the question as stated is mostly ideological.

---

Pros: They are an effective way to match against input. They are easily configurable and can be separated from code.

Cons: They be hard to read. They are not performant. If performance is a concern do not use them.

---

Pro: It works and it's simple.

Con: There are none.

Why ask? Perhaps you have something more specific you'd like to know?
