Observer pattern is a design pattern in which an object maintains a list of its dependents and notifies them automatically of any state changes.

Creating immutable in Java

• Use final keyword to make variables immutable

• Use private constructor to prevent object modification

• Use defensive copying to prevent modification of mutable objects

• Use enum to create immutable objects

• Use a browser extension to disable CORS restrictions during development

• Use a server-side proxy to forward requests to the target server
