# Java Using Redis ## Installation Before starting to use Redis in Java, we need to ensure that the Redis service and the Java Redis driver are installed, and that your machine can use Java normally. For Java installation and configuration, you can refer to our (#). Next, let's install the Java Redis driver: * First, you need to download the driver package [**Download jedis.jar**](https://mvnrepository.com/artifact/redis.clients/jedis), make sure to download the latest driver package. * Include this driver package in your classpath. > This site provides a download of the 2.9.0 jar version: [jedis-2.9.0.jar]( * * * ## Connecting to the Redis Service ## Example import redis.clients.jedis.Jedis; public class RedisJava{public static void main(String[]args){//Connect to local Redis service Jedis jedis = new Jedis("localhost"); // If Redis service has a password, the following line is needed, if not, it's not required// jedis.auth("123456"); System.out.println("Connection successful"); //Check if the service is running System.out.println("Service is running: "+jedis.ping()); }} Compile the above Java program, ensuring the driver package path is correct. Connection successfulService is running: PONG * * * ## Redis Java String Example ## Example import redis.clients.jedis.Jedis; public class RedisStringJava{public static void main(String[]args){//Connect to local Redis service Jedis jedis = new Jedis("localhost"); System.out.println("Connection successful"); //Set redis string data jedis.set("tutorialkey", "www..com"); // Get stored data and output System.out.println("The string stored in redis is: "+ jedis.get("run
