public interface DoubleStack
extends Stack<java.lang.Double>

A type-specific Stack; provides some additional methods that use polymorphism to avoid (un)boxing.

the top of the stack.

top

@Deprecated
default java.lang.Double top()

Deprecated.

Please use the corresponding type-specific method instead.

the top of the stack.

peek

@Deprecated
default java.lang.Double peek(int i)

Deprecated.

Please use the corresponding type-specific method instead.

Peeks at an element on the stack (optional operation).

This default implementation just throws an UnsupportedOperationException.

This default implementation delegates to the corresponding type-specific method.
