Can we catch errors in java code

[Ram Chhabra]

Hi,

Can we catch error in java code like, can we catch OutOfMemoryError, ThreadDeath etc.

Thanks,
Ram

Yes you can, Error is a sublass of Throwable.

Thanks,
Can you please give any one error which we cannot handle

[kurt hanni]

All error objects can be handled. they are all subclass of Error which is a subclass of Throwable.

Remember you must avoid handling errors.

And there is nothing much you can do even you catch an Error.

Thanks a lot for clarifications

Depends on the error. A NoClassDefError means a class available at compile time is no longer available. A UnsatisfiedLinkError means a native library cannot be used (it can't be found, or it's missing a dependency). You can catch both and decide to use a workaround.

But I agree that catching errors should be done with very much caution. And OutOfMemoryErrors should never be caught at all.
