Constructor Parameter List

The constructor is used when an object is constructed. Most of the work in constructing an object is automatically done by the Java system. Usually you need to write only a few statements that initialize a instance variables. The constructor for Cone will initialize the three variables of the object.

The parameter list of a constructor looks like this:

dataType parameterName , dataType parameterName ,  and so on

Each dataType is the type of one item of data that will be handed to the constructor, and each parameterName is a name that is used for that item of data.

Here is the class definition, with the constructor partially finished:

public class Cone
{
  // instance variables
  private double radius;  // radius of the base
  private double height;  // height of the cone

  // constructor
  public Cone(  ,   )
  {



  }

  // methods

}
