okay I have been working on a little project of my own for a while.
At the moment it prints out the chapters read and once 100% of the chapters read is greater than 100 it shows on the next line of my code the number of times the book is read.
Now problem is that when the book is read 4 times it shows as %400. I am sure this can be done with either an if statement or a for loop but I wouldnt know where to start. I also know it involves my 2 variables b and show. So any ideas or if you could point me in the right direction that would be most helpful.


import javax.swing.*;
import java.awt.event.*;
import java.awt.*;

public class percentbible extends JFrame implements ActionListener
{
public percentbible()
{
setLayout(new BorderLayout(550,550));
JButton bibone =new JButton ("percentage of bible complete /n calculation ");
add(bibone,BorderLayout.NORTH);

bibone.addActionListener(this);
}
public void actionPerformed(ActionEvent e)
{
String a;
//enter in number for a string
a=JOptionPane.showInputDialog(null,"enter chapters of bible read","",JOptionPane.INFORMATION_MESSAGE);
//turn string into number
long num = Long.parseLong(a);
long chapno = 1189;



double calc= ((double)num/(double)chapno)*100.0;
String show;
//convert integer into string
show = Double.toString(calc);
//display calculation
String b; // string for printing out chapters read
long chapread = num; //the number taken in from the chapters read
long timesbookread = chapread/chapno; //calulation to work out number of times read bible
b = Long.toString(timesbookread); // number goes into the string

JOptionPane.showMessageDialog(null,show+"\n no of times reading whole book"+b,"percentage of chapters read",JOptionPane.INFORMATION_MESSAGE);
}



}
