The garbage collector only collects unreferenced data, therefore there are
such things as memory leaks if you maintain a reference to the data. For
instance, by creating a static variable or a thread and then stuffing data
into the variable or into a member of the thread. For instance,
static Vector allMemory = new Vector();
...
for (;;) {
allMemory.addElement(new String("what a waste of memory"));
}
...
There can also be infinite loops that gobble up memory:
while (! done) {
... allocate some memory ...
... forget to change condition leading to exit from loop ...
}
Eventually this will throw an OutOfMemory exception, thus exiting the loop.
In this second case the memory will be reclaimed by the GC.
