How to handle StackOverflowError

Question

What are the reasons for StackOverflowError Exception and whether it is checked or unchecked exception?

Check the elements that you are sending to stack. If You are passing more number of elements to stack, you might get this error.! — Karthikeyan, Feb 15 '16 at 12:20
`StackOverflowError` extends `Error`. Hence, it is not required to catch it. It often happens when entering an infinite loop of recursive method calls. — Arnaud Denoyelle, Feb 15 '16 at 12:21

A StackOverflowError is an Error. Is not an Exception, so is not a checked or unchecked Exception.

The class hierarchy is the following:

                  Throwable
                      |
       +--------------+----------------+
       |                               |
     Error                         Exception 
       |                               |
       |                       +-------+----------------+
       |                       |                        |
StackOverFlowError       RuntimeException         SQLException
                               |
                               |
                      NullPointerException

Errors extends Error.

Checked exceptions extends Exception

Unchecked exceptions extends RuntimeException

This error happens when your stack has too deep calls of methods.

For example if you don't remember to define an exit strategy from a recursive function you can have a StackOverflowError.
