Solution to 30cd: Heap exhaustion
See code at solutions/code/tutorialquestions/question30cd
Examine class HeapExhaustion and compare it with your solution.
Running class HeapExhaustion from the sample solution three times in succession, I get the following output:
Length of list before memory exhausted: 11451103
Length of list before memory exhausted: 11451103
Length of list before memory exhausted: 11451103
The fact that the same number of objects added to the list before memory is exhausted in all three runs suggests (though of course provides no guarantee) that the Java Virtual Machine's memory allocator is behaving deterministically, allocating objects in the same manner on each run of the program.
