Answer
Stack unwinding is the process of popping stack frames as the program searches for an exception handler.
When an exception is thrown, the Java runtime looks for a matching catch block by unwinding the stack, meaning it exits methods until it finds a handler. This allows exceptions to propagate up the call stack, as seen when an error in an order-processing method is caught in the main checkout method.
