What's wrong with my code?
Code:
import java.awt.*;
import java.awt.font.*;
import java.awt.geom.*;
import java.text.DateFormatSymbols;
import java.util.Calendar;
import java.util.GregorianCalendar;
import javax.swing.*;
public class tester
{
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable()
{
public void run()
{
FontFrame frame = new FontFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
});
}
}
class FontFrame extends JFrame
{
public FontFrame()
{
setTitle("This week (2010)");
setSize(500,250);
CalendarComponent component = new CalendarComponent();
add(component);
}
}
class CalendarComponent extends JPanel
{
public void paintComponent(Graphics g)
{
Graphics2D g2 = (Graphics2D) g;
GregorianCalendar d = new GregorianCalendar();
int today = d.get(Calendar.DAY_OF_MONTH);
int week = d.get(Calendar.WEEK_OF_MONTH);
int month = d.get(Calendar.MONTH);
String dates = "";
String message = "";
d.set(Calendar.DAY_OF_WEEK,1);
//print weekday name
String[] weekdayNames = new DateFormatSymbols().getShortWeekdays();
for (int i=0; i < 8; i++)
{
dates = dates + weekdayNames[i] + " ";
}
Font f = new Font("Courier", Font.BOLD, 23);
g2.setFont(f);
FontRenderContext context = g2.getFontRenderContext();
Rectangle2D bounds = f.getStringBounds(dates, context);
double x = (getWidth() - bounds.getWidth())/2;
double y = (getHeight() - bounds.getHeight())/2;
//add ascent to y to reach the baseline
double ascent = -bounds.getY();
double baseY = y + ascent;
g2.drawString(dates, (int) x, (int) baseY);
do
{
//print day
int day = d.get(Calendar.DAY_OF_MONTH);
int weekday = d.get(Calendar.DAY_OF_WEEK);
int firstDayOfWeek = d.getFirstDayOfWeek();
message = message + day;
//marks current date with *
if(day == today) message = message +"*";
if (day == day) message = message +"| ";
if (weekday == firstDayOfWeek) message = message + "\n";
//advance to the next day
d.add(Calendar.DAY_OF_WEEK,1);
}
while (d.get(Calendar.MONTH) == month);
//measure the size of the message
bounds = f.getStringBounds(message, context);
//set (x,y) = top-left of the text
x = (getWidth() - bounds.getWidth())/2;
y = (getHeight() - bounds.getHeight())/2;
//add ascent to y to reach the baseline
ascent = -bounds.getY();
baseY = y + ascent;
//draw the message
g2.drawString(message, (int) x, (int) baseY+35);
}
}
Trying to make my program output something like this,

however, I can't get the string to move to the next line for every week.
Also, the week ends a day late.
for example, the first week ends on the 7th, the second week on the 14th, and the third week on the 21st.
