Private means hiding the detail implementation of data. For a simple program, which means to teach a kid about OOP, getDiameter() may not mean anything but reduendent. For any serious programing, that circle may very well locate in another address space, i.e. a different program running on another computer. Then you will appreciate the advantage of get and set methods.
