The usual push and pop operations. Below is the syntax highlighted version of Stackjava from 43 Stacks and Queues. The usual push and pop operations.

Increases the capacity of this vector if necessary to ensure that it can hold at least the number of components specified by the minimum capacity argument. Further the stack in Java has one constructor and five methods which are all described below. It extends class Vector with five operations that allow a vector to be treated as a stack.
