Creating a memory leak with Java
There is a "Garbage Collector" in Java, but does this mean that memory leaks are totally absent in a Java applications? If not, how and why do they happen?
I am more interested in scenarios in applications using JavaSE.
Depends on how you define memory leak.
If you specifically mean having allocated memory that is no longer referenced by some memory root, then no, the garbage collector will eventually clean all of those up.
If you mean generally having your memory footprint grow without bound, that is easily possible. Just have some collection referenced by a static field and constantly added to.
