What is the difference between point-to-point and publish/subscribe messaging in JMS?

Point-to-point and publish/subscribe are two common messaging models in the Java Messaging Service (JMS) architecture.

Point-to-Point Messaging

Point-to-point messaging involves a sender sending a message directly to a specific receiver, known as a queue. The message is stored until the receiver retrieves it. This model is suitable for one-to-one communication and ensures message delivery to a single recipient.

Publish/Subscribe Messaging

Publish/subscribe messaging involves a publisher broadcasting messages to multiple subscribers, known as topics. Subscribers can receive all messages or filter based on their interests. This model supports one-to-many communication and allows multiple recipients to receive the same message.
