Because nobody has the slightest idea what the hell it could mean.
Because a pointer is a memory location, it would be pointless to multiply 2 or more memory locations. The data pointed to by the pointer is a different matter if the data are numeric in nature.
Java doesn't have pointers. C++ has pointers.
A pointer is simply a variable that can store a memory address and has the same purpose in both languages. The only real difference is that C++ pointers can point at objects (instances of a class) and indirectly invoke their methods, whereas pointers in C (which is not object oriented) cannot.
A pointer is simply a variable that stores a memory address. Thus a pointer to an object is simply a variable that stores the memory address of an object. Since pointers are variables, they require memory of their own. Pointers may also be constant, which simply means you cannot change what they point to. Pointers can also be dereferenced to provide indirect access to the memory they point to -- hence they are known as pointers. However, unlike C, pointers are not the same as references. In C++, a reference is simply an alias for a memory address and requires no storage of its own.
Because no-one knows what the sum of two pointers should be...of course you can convert them to integers and then sum them, but why on earth would you do that?
The expression c multiplied by c multiplied by c can be written as c^3, which is read as "c cubed." This represents c raised to the power of 3, meaning c multiplied by itself three times. So, c^3 is equal to c * c * c, which simplifies to c multiplied by c squared.
C does not have stream pointers.
Java does not support Pointers and hence you cannot use it in Java.
Pointers is a very powerful feature that is available in the C programming language but at the same time it is very confusing and many of the issues that arise out of C programs is because of incorrect or inappropriate usage of pointers. Hence the creators of Java language opted to exclude the pointers feature and create Java as a language where the programmer cannot access the native memory area and the memory accessing is left to the system to be taken care of.

Nothing.
Yes, you can use pointers in the C#, but to some extent. Links are added with more details.
