A full answer can be found indepth on StackExchange by Joachim Sauer, so here is my short summary. Pointers in C can perform pointer arithmetic, whereas java references can not. As you can't manipulate the underlying value of a reference in Java. Java references are strongly typed. Whereas a pointer in C can be cast from int* to char*. In Java you can cast an Object ref to a String, only if that Object is actually a String This makes Pointers in C more flexible/powerful than Java References. However, this also means that Pointers in C are more dangerous.
