Restore and Resync question from a n00b

Question

Okay, I have the need to erase and reload my Touch 2G (I just got it last week, but it appears that I have some corrupted data on it already.) I have about 500 songs in my PC's iTunes library, as well as several applications and a few pics.
So, if I need to reload it without erasing all the stuff in my iTunes library, I need to RESTORE from iTunes (which as I understand it erases the iPod), then unplug it, plug it back in and do a re-sync, right?
TIA for any answers.

Answer 1

Don't use a semicolon after the if statement.
Also, you cannot use "and" in Java - use "&&", although in this case you don't need it.
The code below is a "cleaned up" version of yours. Hopefully it shows a better way to structure this. The "gt;=" means "<="
e.g
public String grade (int average) {
    String rGrade = "";
    if (average >= 91) {
         rGrade = "A";
    } else if (average >= 81) {
         rGrade = "B";
    } else if (average >= 71) {
         rGrade = "C";
    } else if (average >= 61) {
         rGrade = "D";
    } else {
         rGrade = "E";
    // These print statements should probably be in the calling method
    System.out.println ( );
    System.out.println ("Final grade: " + rGrade);
    return rGrade;
}
