 > The balking pattern is a software design pattern that only executes an action on an object when the object is in a particular state. For example, if an object reads ZIP files and a calling method invokes a get method on the object when the ZIP file is not open, the object would "balk" at the request.

 ## Programmatic Example of Balking Pattern in Java
 
 This example demonstrates the Balking Pattern in a multithreaded Java application, highlighting state management and concurrency control. The Balking Pattern is exemplified by a washing machine's start button that initiates washing only if the machine is idle. This ensures state management and prevents concurrent issues.

 > While not a formalized "Gang of Four" design pattern, Bloc is widely used in state-driven applications. It centralizes state management and propagates state changes to registered observers, following principles of separation of concerns.

 ## Programmatic Example of Bridge Pattern in Java
 
 Imagine you have a weapon that can have various enchantments, and you need to combine different weapons with different enchantments. How would you handle this? Would you create multiple copies of each weapon, each with a different enchantment, or would you create separate enchantments and apply them to the weapon as needed? The Bridge pattern enables you to do the latter.
