In C++, the std::map class is templated which allows the data types of keys and values to be different for different map instances. For a given instance of the map class the keys must be of the same base type. The same must be true for all of the values.
PowerShell 7 is the replacement for PowerShell Core 6.x products as well as Windows PowerShell 5.1, which is the last supported Windows PowerShell version. [ 110 ] [ 108 ] The focus in development was to make PowerShell 7 a viable replacement for Windows PowerShell 5.1, i.e. to have near parity with Windows PowerShell in terms of compatibility ...
a declarator_list is a comma-separated list of declarators, which can be of the form identifier As object_creation_expression (object initializer declarator) , modified_identifier «As non_array_type « array_rank_specifier »»« = initial_value» (single declarator) , or
To do this, Java allows importing a single class (e.g., import java.util.List). C# allows importing classes under a new local name using the following syntax: using Console = System. Console. It also allows importing specializations of classes in the form of using IntList = System. Collections. Generic. List < int >.

Eventually this gets to the clone() method of Object (the uppermost class), which creates a new instance of the same class as the object and copies all the fields to the new instance (a "shallow copy"). If this method is used, the class must implement the Cloneable marker interface, or else it will throw a "Clone Not Supported Exception". After ...
For example, to check whether an item is included in a list, we need to compare the items for equality. In Standard ML , type parameters of the form ’’a are restricted so that the equality operation is available, thus the function would have the type ’’a × ’’a list → bool and ’’a can only be a type with defined equality.
