FloatLinkedStack

public FloatLinkedStack()

Initialize an empty stack. Postcondition: This stack is empty.

Method Detail

clone

public java.lang.Object clone()

Generate a copy of this stack.

Overrides:

clone in class java.lang.Object

Returns:

The return value is a copy of this stack. Subsequent changes to the copy will not affect the original, nor vice versa. Note that the return value must be type cast to a FloatLinkedStack before it can be used.

Throws:

java.lang.OutOfMemoryError - Indicates insufficient memory for creating the clone.

isEmpty

public boolean isEmpty()

Determine whether this stack is empty.

Returns:

true if this stack is empty; false otherwise.

peek

public float peek()

Get the top item of this stack, without removing the item. Precondition: This stack is not empty.

Returns:

the top item of the stack

Throws:

java.util.EmptyStackException - Indicates that this stack is empty.

pop

public float pop()

Get the top item, removing it from this stack. Precondition: This stack is not empty.

Returns:

The return value is the top item of this stack, and the item has been removed.

Throws:

java.util.EmptyStackException - Indicates that this stack is empty.

push

public void push(float item)

Push a new item onto this stack. The new item may be the null reference.

Parameters:

item - the item to be pushed onto this stack Postcondition: The item has been pushed onto this stack.

Throws:

java.lang.OutOfMemoryError - Indicates insufficient memory for increasing the stack's capacity.

size

public int size()

Accessor method to determine the number of items in this stack.

Returns:

the number of items in this stack
