Constructor Detail

### IntStack

    public IntStack()

  **For internal use only** Default constructor. Note that the default block size is very small, for small lists.

### IntStack

    public IntStack(int blocksize)

    The object at the top of this stack.
  Throws:
    java.util.EmptyStackException - if this stack is empty.
  Since:
    JDK1.0

### quickPop

    public void quickPop(int n)

  **For internal use only** Quickly pops a number of items from the stack.
  Throws:
    java.util.EmptyStackException - if this stack is empty.

### peek

    public int peek()

  **For internal use only** Looks at the object at the top of this stack without removing it from the stack.

### search

    public int search(int o)

  **For internal use only** Returns where an object is on this stack.
  Parameters:
    `o` - the desired object.
