      A Stack Manipulation in Java is one that relies on a stack machine model for passing parameters. Several programming languages fit this description, notably Forth, RPL, PostScript, and also many Assembly languages (but on a much lower level).
Stack-oriented programming languages operate upon one or more stacks, each of which may serve different purposes. Because of this, programming constructs in other programming languages may need to be modified for use in a stack-oriented programming language. Adding to this, some stack-oriented programming languages operate in Reverse Polish or postfix notation - that is, the arguments or parameters for some command are stated before the actual command itself. For example, in RPN, one would say "2, 3, multiply" instead of "multiply, 2, 3" (prefix or Polish notation) or "2 multiply 3" (infix notation). Since the stack is the key means of data manipulation in a stack-oriented programming language, often these languages provide some sort of stack manipulation operators. Commonly provided are dup, to duplicate the element at the top of the stack, exch (or swap), to exchange elements at the top of the stack (the first becomes the second and the second becomes the first), roll, to cyclically permute elements in the stack or on part of the stack, pop (or drop), to discard the element at the top of the stack (push is implicit), and others. These become key in studying procedures.
