Welcome back to our Redis course! Now that you know how to connect to a Redis server using Java, it's time to move forward and explore how to work with numbers in Redis. This unit builds on our previous lesson, so make sure you're comfortable with establishing a connection to a Redis server using the Lettuce API.
In this lesson, you will learn how to:
- Set numeric values in Redis using Java.
- Retrieve numeric values using the Lettuce API.
It's important to note that in Redis, numbers are stored and handled as strings because Redis inherently treats all data as string values. While this allows Redis to store numeric and non-numeric data uniformly, it also means numeric values need to be explicitly parsed into their appropriate types (e.g., int, double) in your application code if you want to perform arithmetic or logical operations.
Here's the code snippet that we'll be working with:
