lWhen you write multiple constructors, sometimes we like to have the contructors call another function to
actually get the work done (to
minimize duplication of code)
lIn C++ we do this by
writing named member functions
lIn Java we do this by having one constructor call
another constructor with a
special usage of the this pointer!
•This can only
happen once within a constructor
•It must be the first thing a constructor does
•list (int i) { //first
constructor which does the real work}
•list (int i, int j)
{this(i); //calls the constructor with
an int }
