How is memory allocated?

The new keyword allocates memory on the Java heap. The heap is the main pool of memory, accessible to the whole of the application.

If there is not enough memory available to allocate for that object, the JVM attempts to reclaim some memory from the heap with a garbage collection.

If it still cannot obtain enough memory, an OutOfMemoryError is thrown, and the JVM exits.
