How do you destroy an array?
That depends on the programming language. In Java - since you posted the question in the Java category - an array is treated like an object. That means that you usually don't need to do anything: as soon as there are no more variables that point to the array - and that usually happens when the method that declares the array finishes running - it will become available to be destroyed automatically by the garbage collector. The programmer doesn't have much control over WHEN exactly this happens; the Java Virtual Machine decides when it's convenient to run the garbage collector.
