Hello, In JAVA there can be the two kinds if the exceptions such as the Unchecked Exceptions and Checked Exceptions. So, these two types of the exceptions can be based on the checking of exceptions at the compile time. There can be also a classification that can be the based on Run-Time in JAVA, such as the synchronous and asynchronous exceptions. I think You can understood from this information.

The Exception can have the subclass that can be as the Checked Exception, avoiding the class Run-time Exception and all of its subclasses. The programmers of the client can be forced by building the exceptions to deal the possibility that can be thrown by the exception. The Unchecked exceptions can be the Run-Time Exceptions and any of can be its subclass. Class Error and its subclasses also are unchecked.
