They exist in different contexts. Handles are like... well handles (or keys, tickets, references etc), to access objects (like files, sockets, resources) you have opened (created, allocated, etc); in the program they can be integers or pointers.
3 pointers...
Pointers in C are generally the thing that gives learners the most trouble. When C code is not written correctly with respect to pointer use, the resulting bugs can often be very difficult to find and correct. On the other hand, pointers are absolutely necessary in some cases.The designers of Java wanted to make programming easier and hence avoided adding pointers to the language. Java does have object references which accomplish much of what pointers accomplish albeit in a safer way.
All programming languages implement pointers, but not all languages allow low-level access to memory through a raw pointer. Java, for instance, uses resource handles and smart pointers rather than raw pointers, however the actual allocation of memory is handled by the Java virtual machine (JVM) so there is no need for low-level raw pointers.
An array of pointers is a contiguous block of memory that contains pointers to other memory locations. They essentially allow non-contiguous memory locations to be treated as if they were an actual array.
the move pointer
you put different colored pencil fillings in the pencil
This are the 6 different pencil cases: '''2B, HB, 4A, 4B, 2A, 4C.'''
Any pencil can draw... but, pencils made specifically for drawing, have different darkness (smoothness) grades so we can make different areas light or dark which is difficult with just one pencil...got it?
Mouse Pointer.
because the pencil would like to be that color and not a different color
Sure.

They are pointers without type
Yes, same shark, different name.
The main body of a pencil is made from soft wood, the 'lead' is made from graphite. The lead can come in many different sizes depending on the pencil holding it.
Java does not support pointers.
