import javax.swing.JOptionPane;

public class BookClubPoint {
public static void main(String[] args) {
// TODO code application logic here
String A = "You have earned 0 points";
String B = "You have earned 5 points";
String C = "You have earned 15 points";
String D = "You have earned 30 points";
String E = "Yo have earned 60 points";
int points;
String Bkacess =JOptionPane.showInputDialog(null,"Enter the number of books: ");
int books = Integer.parseInt(Bkacess);
if( books >= 0)
JOptionPane.showMessageDialog(null, A );
else
if( books >= 1 )
JOptionPane.showMessageDialog(null, B );
else
if ( books >= 2 )
JOptionPane.showMessageDialog(null,C);
else
if ( books >= 3);
JOptionPane.showMessageDialog(null,D);
else
JOptionPane.showMessageDialog(null, E);
}
}

my code doesn't run, why?

Answer 1

remove the semicolon after if(books>=3)

Answer 2

also: string E should start with "You" not Yo.
also: your first test will be true for any number of books so you will always get 0 points.

Reverse the order of books or use a switch statement that defaults to max points,.

Answer 3

Above comment should read: reverse the order of if statements

Answer 4

int books = Integer.parseInt(Bkacess);
if( books > 3)
JOptionPane.showMessageDialog(null, E);
else
if( books == 3 )
JOptionPane.showMessageDialog(null,D);
else
if ( books == 2 )
JOptionPane.showMessageDialog(null,C);
else
if ( books == 1)
JOptionPane.showMessageDialog(null, B );
else
JOptionPane.showMessageDialog(null,A);
