Secs 67.6
Methods of identical name to class are special -- they are constructors
mPoint() { /* Default Constructor */
  • x=0;
  • y=0;
}
We can overload method to define different versions with different numbers and types of arguments
mPoint(int _x, int _y) { /* Constructor to set Specific Initial values */
  • x = _x;
  • y = _y;
}
mPoint can have other methods to set its instance variables such as:
public void setDelta(int _dx, int _dy) {
  • dx = _dx;
  • dy = _dy;
}
