In Android development, Handlers are used to facilitate communication between the main thread and background threads, enabling message passing and UI updates between them.
In server-side development, Handlers can be used to manage client requests and distribute them to different processors for processing.
In event-driven programming, the Handler pattern can be used to handle asynchronous events. When an event occurs, the Handler is responsible for processing the event and calling the appropriate handler.
In a message queue system, Handlers can be used to handle the sending and receiving of messages, ensuring their order and reliability.
When a system needs to implement delayed or scheduled task execution, Handlers can be used to schedule timed tasks.
