What is the difference between pointers in C and reference in Java

Hi Chikki
The references used in Java are a higher level view of the lower level pointers in C.Internally all references are pointers(I'd guess so).

Hi chikkireddi, You should probably post this question in one of the "Java in general" forums. After, of course, registering with a proper name

I have been in debate after debate over this very question. Please know that there are NO pointers in JAVA. Everything in JAVA is a reference. But also keep in mind that the term reference in JAVA means something different than it does in the C language.

I think of references like this:
They contain a pointer to an object that is in the reference type's inheritance tree.
They contain a list of methods signatures that they can call from the object that it's pointing to.

Pointers in C++ can be manipulated.
This is not true in Java - you can not do operations on references.
