About NamePrinter

• To create a NamePrinter, you have 2 options

  1. implement NamePrinter interface, see src/main/java/th/ac/kmitl/science/comsci/example/nameprinters/EarlyNamePrinter.java, or
  2. Extend NamePrinterBase and override getName() to change the name, see src/main/java/th/ac/kmitl/science/comsci/example/nameprinters/NamePrinterBaseExampleNamePrinter.java

• To print out a name to PrintWriter, pass a PrintWriter instance to NamePrinter.print()

• To print out all NamePrinters in java.th.ac.kmitl.science.comsci.example.nameprinters package, you can use NamePrinterLoader to iterate through all NamePrinter.

1. how can you simplify your code and do it as guideline for your friends to follow up and extend the structure you define. (I think with this code they won't understand)

@mahasak @khemtat @oTh3l3ankky what you think ???
