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

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.


  • 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.
