What types of exceptional situations can you name in programming?

In programming, exceptions can be classified into several types:

• System exceptions — errors related to hardware or system failures, such as stack overflow, out of memory.
• Runtime exceptions — errors that occur during program execution, such as division by zero, null reference (NullPointerException in Java).
• Checked exceptions — errors that must be handled or declared in the method signature, such as IOException when working with files.
• User-defined exceptions — created by developers for specific errors in business logic.

In Android, common exceptions include NetworkOnMainThreadException (network operation on the main thread), ActivityNotFoundException, and others.
