Is it possible to catch out of memory exception in java? [duplicate]

Question

I'm developing a program that would require huge amount of memory, and I want to catch when out-of-memory exception happens. I had heard this is not possible to do, but curious if there is any development on this end.

Answer 1

It's not an exception; it's an error: java.lang.OutOfMemoryError

You can catch it as it descends from Throwable:

try {     // create lots of objects here and stash them somewhere } catch (OutOfMemoryError E) {     // release some (all) of the above objects } 

However, unless you're doing some rather specific stuff (allocating tons of things within a specific code section, for example) you likely won't be able to catch it as you won't know where it's going to be thrown from.

Answer 2

It's possible:

try {    // tragic logic created OOME, but we can blame it on lack of memory } catch(OutOfMemoryError e) {    // but what the hell will you do here :) } finally {    // get ready to be fired by your boss }
