Java *does* have pointers, but they are called _references_ (the clue is in the name `Null**Pointer**Exception`, which is thrown when you invoke a method on a null _reference_). They differ from C++ pointers insofar as you can't do arithmetic on them. – Andy Turner Sep 21 '21 at 15:22

... and that a pure Java program cannot get into a situation where a reference points to some random place in memory. – Stephen C Sep 21 '21 at 15:25
