Welcome to the first lesson of our Redis course! In this unit, we'll start with the very basics — connecting to a Redis server. Understanding how to establish this connection is essential since it forms the backbone of all the operations you'll perform with Redis. By the end of this lesson, you’ll be confident in setting up a connection to a Redis server and verifying that connection through simple operations.

In this lesson, you will learn how to:

1. Connect to a Redis server using Java.
2. Verify your connection by storing and retrieving a value.

Here’s the simple code you’ll be working with:

Let's break down the code:

• We import classes from the Lettuce API to provide the Java interface to Redis.
• We create a RedisClient object to establish a connection to the Redis server running on at port and database — the default database.
