This tutorial is aimed to help you master Regular Expression in Java.

When I started programming, java regular expression were a nightmare for me.

If you have gone through all the tutorials available on this site you are probably starting to feel quite confident in your ability to automate testing of a web site.

Input String matches regex - true Exception in thread "main" regex. Java Regex Quantifiers can be used with character classes and capturing groups also.I will also come back here to refresh my Java Regex learning.Regular expression in java defines a pattern for a String. Pattern Example.main(Pattern Example.java:13) So if your requirement is just to check if the input String matches with the pattern, you should save time and lines of code by using simple String matches method.So

So \1 is referring to “a2” and hence it returns true. Try to understand this scenario for statement 3 and 4 yourself.

🙂Now we will look at some important methods of Pattern and Matcher classes.

I am pretty sure by the end this you will be able to automate testing of most sites and the things that you can't do will hopefully be covered in future advanced tutorials.
