Java / Exception

Explain Throwable class.

The Throwable class is the superclass of all errors and exceptions in the Java language. Only objects that are instances of this class (or its subclass) are thrown by the Java Virtual Machine or can be thrown by the Java throw statement. Similarly, only this class or one of its subclasses can be the argument type in a catch clause.

A throwable contains a snapshot of the execution stack of its thread at the time it was created. It can also contain a message string that gives more information about the error. It also can contain a cause : another throwable that caused this throwable to get thrown.
