Introduction to the Observer pattern:The Observer pattern is also known as the Publish subscription pattern. is a one-to-many dependency, that is, when the state of an object (the message publisher) changes, other objects (subscribers) automatically perform their actions when they receive the message. Objects that are involved in this pattern: 1. Message issuer (one)1.1 The message Publisher will first establish an array of notifications arr, which is used to store the Subscriber information ob
