Hi friends and how are you? i have a problem i need to write a java program which has a two java packages, one has the interface and the other has classes, with each class calculating the conversion of the South african rand to US dollar, rand to euro, rand to pound, rand to brazil real, rand to danish krone, rand to japan yen and rand to china yaun.each class with a number and date format; and locale. When i run it must show a dialog box of all the conversions of these different countries number,date format and locale(latest date and time in their rspective langauges). e.g Rand[R10] to pound[$70] american format date and locale, same goes for the rest.It must define polymophysm and have encapsulation. Pls friends. Thank you.
