What are the advantages and disadvantages of using threads in programming?

Advantages of using threads:

• Allow multiple tasks to run in parallel, improving application responsiveness.
• Efficient for input-output operations, without blocking the main thread.
• Used for parallelizing computations on multi-core processors.

Disadvantages:

• Complexity of synchronization and state management, which can lead to errors (race conditions, deadlocks).
• Increased overhead for thread creation and context switching.
• Difficulties in debugging and testing multithreaded code.

In Android, threads are often used to perform background tasks so as not to block the UI thread.
