Still stuck with the same convertion problem. guyz, the real problem
arises when i use private class. my prof told us that we can only use
private class, switch, if/else, do/while, constructor and loops. He
gave us an example in which it goes somethin' like this:

private "i don't remember what's next... "


then the switch statement....

Case1.............
break;
...............Case 9..........
break.........

then he provided us with the:
public class....
InputStreamReader....
BufferedReader....
