What is the purpose of Throwable in Java?
Throwable is the superclass of all errors and exceptions in Java, serving to represent any Java program error or exception that can be thrown. There are two subclasses of the Throwable class: Error and Exception. Error represents serious issues usually caused by system problems that the program cannot handle, while Exception represents general problems typically caused by program errors or external factors that can be recovered through handling to restore normal program operation. In Java, when an exception or error occurs, the Throwable object can be manually thrown using the throw keyword, or caught and handled to address exceptional situations. The Throwable class provides methods such as getMessage() and printStackTrace() to retrieve exception information and print exception stack trace.
