what are checked and unchecked exceptions ?

[teja dharma]

can any body tell me what are checked and unchecked exceptions with one simple example.

[Ruben Soto]

If you have any code that might throw a checked exception, you must either enclose it in a try/catch clause that handles that potential exception, or must declare the checked exception in a throws clause in the containing method. Basically, the compiler will check that you do that with code that potentially throws checked exceptions. The compiler doesn't care about unchecked exceptions.

Checked -> Exceptions caught by compiler
unchecked -> Exceptions not caught by compiler( you can write your own catch block to catch at runtime )

[Jesper de Jong]

Exceptions are never caught by the compiler, because exceptions happen at runtime, not at compile time.

Checked exceptions are exceptions that are checked by the compiler - in other words, the compiler checks to see if you handle them with a try ... catch block, or declare that you throw them further with a throws-clause in the method declaration. If you don't handle or declare a checked exception in a throws-clause, the compiler will stop with an error.

Unchecked exceptions are not checked by the compiler - you do not need to catch them or declare them with a throws-clause.
