Displaying the System Time In a Frame.

Question

import javax.swing.*;
public class Window1 {
public static void main(String[] args) {
JFrame win = new JFrame("Window1");
JTextArea Timedata = new JTextArea(10, 30);
win.getContentPane().add(tA);
win.pack();
win.setVisible(true);
tA.setText ("This is an editable text area");
public class TimeData {
private long hours, minutes, seconds;
public TimeData(long millis) {
seconds = (millis/1000)%60;
minutes = (millis/(60*1000))%60;
hours = (millis/(60*60*1000))%24;
public String toTimeString() {
return (String.valueOf(hours) + ":" + String.valueOf(minutes) + ":" + String.valueOf(seconds));
public long getHours() { return hours; }
public long getMinutes() { return minutes; }
public long getSeconds() { return seconds; }
public class SystemTimeTest {
public static void main(String[] args) {
String s1;
TimeData t1;
t1 = new TimeData (System.currentTimeMillis());
s1 = t1.toTimeString();
System.out.println(s1);
// How do you get the system time to display in the frame, using the above classes. unable to find the information through books and online tutorials. Please Help.

Answer 1

In future Swing related questions should be posted into the Swing forum.
I am not sure what tutorials you are using but they can't be very good if you did this. Try this tutorial instead http://java.sun.com/docs/books/tutorial/uiswing/components/index.html
And please post some code that might compile without syntax errors next time.
JTextArea Timedata = new JTextArea(10, 30);
win.getContentPane().add(tA);There is no tA defined anywhere.
