A cleaner approach is to designate the constructor that takes the greatest number of arguments

as the “master constructor” and have its implementation perform the required validation logic. The

remaining constructors can make use of the this keyword to forward the incoming arguments to

the master constructor and provide any additional parameters as necessary. In this way, we only

need to worry about maintaining a single constructor for the entire class, while the remaining con-

structors are basically empty.

Here is the final iteration of the Motorcycle class (with one additional constructor for the sake

of illustration). When chaining constructors, note how the this keyword is “dangling” off the con-

structor’s declaration (via a colon operator) outside the scope of the constructor itself:

class Motorcycle

{

public int driverIntensity;



public string driverName;
