Java code for validating date

If you copied a regex written for another programming language, simply paste it into Regex Buddy, select the original language, and then convert the regex to the specific version of Java you're working with.

If you're writing a code library that needs to work with multiple versions of Java, compare your regex between those Java versions to make sure it will work exactly the same with all of them.

Rely on Regex Buddy's clear regex analysis, which is constantly updated as you build the pattern, rather than dealing with the cryptic regex syntax on your own.

Detailed help on that syntax is always only a click away.

The purpose of this guide is to walk through the process of creating a simple Java Spring MVC app that retrieves messages in Office 365 or
