Throwable class is the super class of all the exception types. Below Throwable class there are two subclasses which DENOTES two distinct branches of exceptions -

• Exception - An Exception indicates that a problem has OCCURRED, but it is not a serious system problem. The user programs you write will throw and catch Exceptions.
• Error - It defines exceptions that are not expected to be caught by your program. Exceptions of type Error are used by the Java run-time system to indicate ERRORS having to do with the run-time environment, itself.

Examples of error are StackOverflowError, OutOfMemoryError etc.

Below Exception there is a distinct subclass RunTimeExcpetion - RunTimeExcpetion and its descendants denote the exceptional CONDITIONS that are external to the application, and the application usually cannot anticipate or recover from them.
