using the "this" method in a constructor

When I attempt to compile the following class I get an error message
pointing to one of my constructors stating "wrong number of arguments in
constructor. Can anyone shed some light on what I am missing?
Thanks.

You don't have any constructor which has 3 parameters. When you call this(
hours, 0, 0 ); compiler looks for the constructor with 3 int parameters.
In your following code you don't have any constructor which matches the
above. You have a method public void MyTime( int hours, int minutes, int
seconds ) but this is not a constructor. Constructors won't be having any
return type not even void. If you remove the void from the above method
signature your code will be compiled.

Mike:

I'm not sure you can "this" in that manner. I believe you should just call
the constructor again: MyTime(int,int,int). What is with the double 00
in the default constructor too? Want to just use 0?
