Difference between the Exception and Error in Java.

Posted in: Core Java,Java Exceptions In Java, under Throwable class, there are 2 sub-classes named Exception and Error.

Exception class:

•  It is used for exceptional conditions that user programs should catch.
•  It's also the class that you will sub-class to create your own custom exception types.
•  For example, NullPointerException will be thrown if you try using a null reference.

Error class:

•  It indicates serious problems that a reasonable application should not try to catch.
•  It's used by the Java run-time system to indicate errors having to do with the run-time environment, itself.
• For example, stack overflow is an error.
