The guide will walk you through the installation and usage of the Floodgate Java SDK.
The first step is to install the Floodgate SDK as a dependency in your application using your application's dependency manager.
Now you have the Floodgate SDK installed and imported you can create a new instance of the Floodgate Client.
Using the client object you can now evaluate a flag using the getValue method. The getValue method requires two parameters with an optional third.
This is the Flag Key which you entered when creating the flag.
This is the value which you want the flag to evaluate to if no flag data can be found.
This is an optional value which can be passed containing information about the user. This information is required to evaluate flags when doing user targeting or percentage rollout releases.
The example below shows an evaluation of a flag called my-feature-flag passing in a default value of false.
All our SDKs are open source and you are free to check out what's going on inside them. In fact we encourage contributions from the Floodgate community. You can view the source code on GitHub.
