Jar files for java.util.regex

Question

I need jar files for java.util.regex in my project for input validation if any one can help please help me.Please provide me some websites from where i can download it. Thank you.

Answer 1

The java.util.regex is bundled with the standard Java runtime. (Which means that you don't need to include a separate .jar file to access it.)

To answer your question: It's in the rt.jar file.

Answer 2

The java.util.regex package was added to Java SE 1.4. If you are running an older version of java than that you should really consider upgrading.

Answer 3

The regex classes are in the standard rt.jar that comes with every JDK or JRE download. You almost certainly already have them.
