we cannot classify into checked and unchecked because its an error but we can say its unchecked bcz it only detected at the runtime ...

Hi sir I have a doubt in flyweight pattern like in robot eg we are creating only two object one for human type and other for robotic type as they are cached , their extrinsic value is their coordinates now suppose we have created human type robot and set is coordinate (0,0) and now again we have created another human type robot this time we will get same object which we created before from cache and set it's new coordinate (1,1) Wouldn't it create a problem becoz coordinate of first object is changed from 0,0 to 1,1 and now the robot from 0,0 will display at 1,1 Can u please help me to solve this🙏

Hi sir I have asked this question previously plz reply sir In command pattern we have an invoker, but the client can directly use command and pass the receiver to command there is still lose coupling between client and command. Invoker can only be used for undo operation if we don't want to have undo operation then I think there is no need of invoker. And the uml that I have seen client doesn't have HAS-A relationship with invoker

@ConceptandCoding 9 ай бұрын

No, if client can directly give Command, then it has tight couple with command class. If suppose any command giving process change, client has to make the changes too. That's the last thing which we wanted (i e to make client changes). That's why invoker is added, it's just an abstraction layer for client, so that in future any thing changes it will lead to change in 1 place i.e invoker, bcoz you can have multiple clients but invoker class would be 1. Hope that clarifies

@@yuvhrajverma9665 Yuvhraj, then without invoker it won't be considered as Command pattern, and definitely you can solve the problem without invoker or even without using any design pattern, usage of design pattern is not mandatory. Consider very simple example: let's say i changed the command method name from "switchOnAC" to "turnOnAC" , will this impact client? Yes , client has to change the name too, what if you have 1000s of clients, will you change all? If you have mediator like invoker, you have to change only at invoker and clients remain un impacted
