RuntimeException is the superclass of all the exceptions which may be thrown for many reasons during expression evaluation, but from which recovery may still be possible. On the other hand java.lang.Exception represent errors which can be catch and dealt e.g. Sales tax rate for hotel in Washington DC Would the Gee Bee be allowed to fly today, with so little forward visibility?

Any authentic link would be great help. –Vipin Aug 11 '14 at 7:43 1 @Vipin: It's my personal opinion, but one that many other people share, e.g. Because these exceptions are so common, methods that can throw objects that are instances of RuntimeException or one of its subclasses are not required to declare that fact in their throws i.e.
How to remove element from Array in Java with Exam... Then,.. But first, you need to remember that exceptions are part of the interface exposed by the code; document them.

Unchecked are the sorts of errors that you expect to bring down the application. LinkageError The appropriate subclass of this error is thrown when there is a problem resolving a reference to a class. Although this may seem convenient to the programmer, it sidesteps the intent of the catch or specify requirement and can cause problems for others using your classes. ClassCircularityError This error is thrown when a circular reference among classes is detected during class initialization. Java Runtimeexception Example
On the other hand Unchecked Exception, which are subclass of RuntimeException mostly represent programming errors. The question is, what exactly is the difference between extending RuntimeException and extending Error-- except that extending Error is bad practice?

Unchecked exceptions do not need to be declared in a method or constructor's throws clause if they can be thrown by the execution of the method or constructor and propagate outside Difference Between Error And Runtime Exception In Java You should extend and use Error for these unrecoverable, program crashing problems. Once you've logged the exception, you can report a précis to the user/client with a good conscience (as long as you also include the time of generation — or other correlation

The above would be a Checked Excpetion wouldn't it? OutOfMemoryError This error is thrown when an attempt to allocate memory fails.
That's not because logging more often is a major problem as such, but rather because excessive logging means you just get the log consuming more space without containing more information. share|improve this answer answered Mar 31 '13 at 19:57 Donal Fellows 5,3401432 add a comment| up vote 0 down vote I think you should ONLY throw checked exception when the application This can only be avoided if the Javadoc of the runtime exception happens to be excellently documented which I find is never a case. Actually, checked exceptions tend to be worse for debugging because they're often wrapped which leads to longer and uglier stack traces, or even lost atogether because the wrapping was done wrong.
Many of the standard exceptions are also subclasses of RuntimeException. Not the answer you're looking for? Well in case of an unchecked exception, you will not even know if a call could result in a unchecked. 2. my code compiles fine there are no typos .

My guess is that the philosophy you mention comes from one of two sources: Lazy programmers trying to avoid doing work. Both of these shortcuts allow programmers to write code without bothering with compiler errors and without bothering to specify or to catch any exceptions.
Such problems include arithmetic exceptions, such as dividing by zero; pointer exceptions, such as trying to access an object through a null reference; and indexing exceptions, such as attempting to access So this exceptions can be handled through Exception Handling.

Having to add runtime exceptions in every method declaration would reduce a program's clarity. Why did the designers decide to force a method to specify all uncaught checked exceptions that can be thrown within its scope?
