Java-Kalender-Applet-Problem mit dem ersten Tag des Monats - Java, Kalender, Applet

Damit ist alles erledigt, aber ich habe ein Problem: Mein Kalender behält nicht das Startdatum bei, während wir die Woche durchlaufen.

Hier ist mein Code:

import java.awt.*;
import java.util.GregorianCalendar;

import javax.swing.*;

public class Calendrier extends JApplet {
// Instance Variables
GregorianCalendar calendar = new GregorianCalendar();
int ranger = 7;
int colonne = 7;
String[] semaine = { "Lu", "Ma", "Me", "Je", "Ve", "Sa", "Di" };
JLabel[][] grid = new JLabel[ranger][colonne];
JLabel jlblHeure = new JLabel("Heure: " + ""
+ calendar.get(GregorianCalendar.HOUR_OF_DAY) + ":"
+ calendar.get(GregorianCalendar.MINUTE));
JPanel jpnlCalendar = new JPanel(new GridLayout(7
, 7));
JPanel jpnlHeure = new JPanel(new GridLayout(1, 1));
int day = calendar.get(GregorianCalendar.DATE);
int daysInMonth = calendar.getActualMaximum(GregorianCalendar.DAY_OF_MONTH);
int daysInWeek = calendar.get(GregorianCalendar.DAY_OF_WEEK);

public void init() {
// setting grid
for (int i = 0; i < grid.length; i++) {
for (int j = 0; j < grid[0].length; j++) {
grid[i][j] = new JLabel();
}

}
// grid layout
Container contenu = getContentPane();
for (int i = 0; i < ranger; i++) {
for (int j = 0; j < colonne; j++) {
jpnlCalendar.add(grid[i][j]);
}
}
// adding JPanels + positions
contenu.add(jpnlCalendar);
contenu.add(jpnlHeure, "South");
jpnlHeure.add(jlblHeure);

// draw time
if (calendar.get(GregorianCalendar.MINUTE) < 10) {
jlblHeure = new JLabel("Heure: " + ""
+ calendar.get(GregorianCalendar.HOUR_OF_DAY) + ":" + "0"
+ calendar.get(GregorianCalendar.MINUTE));
}
// draw week days
for (int i = 0; i < semaine.length; i++) {
grid[0][i].setText(semaine[i]);
}
// draw calendar
for (int i = 1; i <= daysInMonth; i++) {
int row = ((i + daysInWeek  ) / 7);
int column = (i + daysInWeek ) % 7;
grid[row + 1][column].setText("" + i);
if (i == day) {
grid[row + 1][column].setText(i + "*");
}
}

}

}

Das funktioniert heute also:

int row = ((i + daysInWeek ) i++ / 7);
int column = ((i + dayInWeek ) % 7);

Aber morgen muss ich -1 zu jedem daysInWeek hinzufügen.

Gibt es eine Lösung, damit dies automatisiert wird?

Zumindest muss ich das nicht jeden Tag ändern. Danke!

Antworten:

Ich habe es selbst gefunden. Hier ist es:

import java.awt.*;
import java.util.GregorianCalendar;

import javax.swing.*;

public class Calendrier extends JApplet {
// Instance Variables
GregorianCalendar calendar = new GregorianCalendar();
int ranger = 7;
int colonne = 7;
String[] semaine = { "Lu", "Ma", "Me", "Je", "Ve", "Sa", "Di" };
JLabel[][] grid = new JLabel[ranger][colonne];
JLabel jlblHeure = new JLabel("Heure: " + ""
+ calendar.get(GregorianCalendar.HOUR_OF_DAY) + ":"
+ calendar.get(GregorianCalendar.MINUTE));
JPanel jpnlCalendar = new JPanel(new GridLayout(7, 7));
JPanel jpnlHeure = new JPanel(new GridLayout(1, 1));
int today = calendar.get(GregorianCalendar.DAY_OF_MONTH);
int daysInMonth = calendar.getActualMaximum(GregorianCalendar.DAY_OF_MONTH);
int daysInWeek = calendar.get(GregorianCalendar.DAY_OF_WEEK);

public void init() {
// setting grid
for (int i = 0; i < grid.length; i++) {
for (int j = 0; j < grid[0].length; j++) {
grid[i][j] = new JLabel();
}

}
// grid layout
Container contenu = getContentPane();
for (int i = 0; i < ranger; i++) {
for (int j = 0; j < colonne; j++) {
jpnlCalendar.add(grid[i][j]);
}
}
// adding JPanels + positions
contenu.add(jpnlCalendar);
contenu.add(jpnlHeure, "South");
jpnlHeure.add(jlblHeure);

// draw time
if (calendar.get(GregorianCalendar.MINUTE) < 10) {
jlblHeure = new JLabel("Heure: " + ""
+ calendar.get(GregorianCalendar.HOUR_OF_DAY) + ":" + "0"
+ calendar.get(GregorianCalendar.MINUTE));
}
// draw week days
for (int i = 0; i < semaine.length; i++) {
grid[0][i].setText(semaine[i]);
}
//conditions for the calendar
calendar.set(GregorianCalendar.DAY_OF_MONTH, 1);
int daysInWeek = calendar.get(GregorianCalendar.DAY_OF_WEEK) - 1;
System.out.print(daysInWeek);
if (daysInWeek == 0)
daysInWeek = 7;
calendar.set(GregorianCalendar.DAY_OF_MONTH, today);

int days = 1;

for (int k = daysInWeek - 1; k < colonne; k++) {
grid[1][k].setText(days + "");
if (days == today)
grid[1][k].setText(days + "*");
days++;
}
// draw calendar
for (int i = 2; i <= colonne; i++) {
for (int j = 0; j < ranger; j++) {
if (days <= daysInMonth) {
grid[i][j].setText(days + "");
if (days == today)
grid[i][j].setText(days + "*");
days++;
}
}
}

}
}
