new linkedlist

Parameter type

Result type

Type...
sequence<? extends Type>

stack<Type>

Creates an empty stack. Optionally, initial values may be specified right in the new linked list creation expression.

stack<string> test = new linkedlist<string> {"A", "B", "C"};


Alternatively, a sequence may be specified that is used to copy elements from.

stack<Type> = new linkedlist<Type> (sequence);
