The class templateListshown in the diagram fragment is a parametrized class with two template parameters:T andn. The signature of the class template includes both of these parameters. The template parameterT represents a type that can be bound to a specific class when the template is instantiated, whilenrepresents an integer value that specifies the multiplicity of elements that can be contained in the list. Therefore, the signature of the class templateListis the ordered set{T, n: Integer}, which includes both the type parameterT and the integer parameternindicating the maximum number of elements the list can hold.
