An exception's type determines whether an exception is checked or unchecked. All exception types that are direct or indirect subclasses of class RuntimeException are unchecked exception. All classes that inherit from class Exception but not RuntimeException are considered to be checked exceptions.
Checked Exception: If client can recover from an exception and would like to continue, use checked exception. Unchecked Exception: If a client can't do any thing after the exception, then raise unchecked exception. Example: If you are expected to do arithmetic operation in a method A() and based on the output from A(), you have to another ...

Dec 23, 2012 · 1. Checked and unchecked exceptions. There are two types of exceptions: checked exceptions and unchecked exceptions. The main difference between checked and unchecked exception is that the checked exceptions are checked at compile-time while unchecked exceptions are checked at runtime.

All other exception classes are checked exception classes. The Java API defines a number of exception classes, both checked and unchecked. Additional exception classes, both checked and unchecked, may be declared by programmers. You could check this via instanceof at runtime, though I don't really see where this would be useful.
Apr 23, 2015 · Unchecked Exception: The classes that extend RuntimeException are known as unchecked exceptions. Unchecked exceptions are not checked at compile-time, but rather at runtime, hence the name. They are also programmatically recoverable problems but unlike checked exception they are caused by faults in code flow or configuration.
checked exceptions are those which can be and should be handled by your code (therefore compiler forces you to handle them) unchecked exceptions are those which lie beyond programmer's control (therefore compiler doesn't forces you to handle them) use the same rule even while creating your custom exceptions.
Aug 12, 2009 · Unchecked are generally actual errors and aren't even in the javadocs more often than not. I guess the most common might be IllegalArgumentException, any method that has any possible combination of parameters that is invalid should throw it. edited Aug 11, 2009 at 22:35. answered Aug 11, 2009 at 21:50.

Note that an unchecked exception is one derived from RuntimeException and a checked exception is one derived from Exception.
