Public class Automobile {private static int Val; private const int NumberOfWheels = 4; // const handles public static void Print () {Console. writeLine ("The automobile have {0} wheels. ", NumberOfWheels);} public static int Size // only static fields can be accessed {get {return Val;} set {Val = value ;}}}
