Getting started with Java SDK

This section describes how to set up and install the Java SDK and how to deploy a feature flag.

Step 1: Setting up

To setup Java SDK, follow these steps:

Create a CloudBees Feature Management account. See Signup Page to create an account.
Get your environment key. Copy your environment key from App settings > Environments > Key.

Step 2: Installing the Java Server SDK

Add the CloudBees Feature Management Java Server package to your application by adding the following in the dependencies block:

implementation 'io.rollout.rox:rox-java-server:5.+'----▼

<dependency>
    <groupId>io.rollout.rox</groupId>
    <artifactId>rox-java-server</artifactId>
    <version>5.0.5</version>
</dependency>▼

Create a container class called Flags.java with the following code. This container class is where we will define all of our feature flags.

import io.rollout.flags.RoxFlag;
import io.rollout.flags.RoxString;
import io.rollout.configuration.RoxContainer;

// Create Roxflags in the Flags container class
public class Flags implements RoxContainer {
  // Define the feature flags
  public RoxFlag enableTutorial = new RoxFlag(false);
  public RoxString titleColors = new RoxString("White", new String[] {"White", "Blue", "Green"});

}▼

Add the following lines of code to your application:

// Initialize container class that we created earlier
Flags flags = new Flags();

// Register the flags container
Rox.register(flags);

// Setup the environment key
Rox.setup("<ROLLOUT_ENV_KEY>");

// Boolean flag example
if (flags.enableTutorial.isEnabled()) {
  // TODO:  Put your code here that needs to be gated
}

// Multivariate flag example
if (flags.titleColors.getValue().equals("White")) {
  System.out.println("Title color is white");
} else if (flags.titleColors.getValue().equals("Blue")) {
  System.out.println("Title color is blue");
} else if (flags.titleColors.getValue().equals("Green")) {
  System.out.println("Title color is green");
}▼

Run your application

Running the application

The flag name is automatically added to the CloudBees Feature Management dashboard after running the application.
