8.4 variable varying number
Use the params modifier before passing parameters, you can implement any number of parameters. Params modifiers are used to declare an array parameter that can receive 0 or more variable elements. Use params to deliver multiple variables, their types must be consistent with the array type specified by the parameter. When the method has both a regular parameter and a params parameter, the params parameter must be the last parameter in the parameter list. Under any circumstances, there can only be a params parameter.
