Functions in Scala

Definition of the function:

Private def methodName (Argname:type,....): Type

The permission modifier defines a method's keyword method name (parameter name: parameter type): return value ={

Method Body:

"" Return value

}

In Scala, you define a function, and if the function has no arguments, you can omit the parentheses
