Summation

Description

Adds the values as selected.

Features

Summation class: with its static methods, the Number class can calculate inheritance classes, return the sum of its values, transform. can handle: Array Collection Map It can decompose these types and also calculate the internal values. Class cannot be inherited or instantiated, its methods cannot be overridden.

Example

summation(x)
Calculates the sum of the values of the corresponding variable specified. It can handle classes inherited from the Number class. Preferred Number, Collection, Map. Can accept classes and interfaces derived from Number[], Collection, or classes and interfaces derived from Map.
x Number, Collection, Map type variable that calculates the sum of its internal values, internal values must be of type Number!
return After deciding on the type, it gives the sum of the values in it.

summationArray(x)
It calculates the sum of the values of the given corresponding variable, and returns it stored in an array. It can handle classes inherited from the Number class. Preferred Number, Collection, Map. Can accept classes and interfaces derived from Number[], Collection, or classes and interfaces derived from Map.
x Number, Collection, Map type variable that calculates the sum of its internal values.
return An array containing the internal values of the expanded selected variable. Its type will be the type of the variable's internal values.

summationCollection(x, classCollectionNameDotClass)
Calculates the sum of the values of the given variable, then Collection returns it as a specified derived class. It can handle classes inherited from the Number class. Collection Specified Collection type Preferred Number, Collection, Map. Can accept classes and interfaces derived from Number[], Collection, or classes and interfaces derived from Map.
x Number, Collection, Map type variable that calculates the sum of its internal values.
classCollectionNameDotClass Must be specified to define the derived type of Collection.
return Returns values as specified Collection type.

summationMap(x, classMapNameDotClass)
Calculates the sum of the values of the given variable and returns it stored as the specified Map class. preferred Number, Collection, Map. Given key can be of Number, Collection, Map type. It can handle classes inherited from the Number class. Specific Map type. preferred Number, Collection, Map. Can accept classes and interfaces derived from Number[], Collection, or classes and interfaces derived from Map.
x Number, Collection or Map type variable that calculates the sum of its internal values. classMapNameDotClass Required to specify the Map derived type. return Map is one of the specified derived classes and returns two values, the key of Map is filled in the specified way. If there is no or the key type or size is not suitable, then the default is to upload.
