Thread: Ticked Off Timer

I believe this code is written well. It compiled with no errors.

1. I need help creating a decrementing timer pause of 1 sec.
2. I also need to make sure the existing pane closes when the new one opens.

I have been reading and I assume it has something to do with swing.timer but am unsure on how to plug this into the while statement.

import javax.swing.JOptionPane;
 
public class Timer{ 
	public static void main(String[] args){
 
		String calculateDayString = JOptionPane.showInputDialog("Countdown Timer Enter How Many Days: ");
 
		int inputDay = Integer.parseInt(calculateDayString);
 
		int calculateDaySeconds = inputDay * 8640;
 
		String calculateHourString = JOptionPane.showInputDialog("Countdown Timer Enter How Many Hours: ");
 
		int inputHour = Integer.parseInt(calculateHourString);
 
		int calculateHourSeconds = inputHour * 360;
 
		String calculateMinuteString = JOptionPane.showInputDialog("Countdown Timer Enter How Many Minutes: ");
 
		int inputMinute = Integer.parseInt(calculateMinuteString);
 
		int calculateMinuteSeconds = inputMinute * 60;
 
		String calculateSecondString = JOptionPane.showInputDialog("Countdown Timer Enter How Many Seconds: ");
 
		int calculateSeconds = Integer.parseInt(calculateSecondString);
 
		String secondsRemainingString = calculateDaySeconds + calculateHourSeconds + calculateMinuteString + calculateSeconds;
 
		int secondsRemaining = Integer.parseInt(secondsRemainingString);
 
		while (secondsRemaining > 0) {
			secondsRemaining--;
			System.out.print("You Have " + secondsRemaining);
		}
 
		System.out.print("Zero Seconds Timer Stopped");
 
	} 
 
}

There's no swing.timer. There is a javax.swing.Timer, most appropriately used in a program that displays a GUI. A program that doesn't create any GUI components may well terminate before the Timer's first cycle is triggered.

There's also java.util.Timer, which is more general-purpose. Read the API, give it your best shot and come back with a specific question if you can't get it to do what you want it to do.

I cant get this to compile but I believe I am now somewhat closer.

I believe I know what I want to do but I have no Idea or example of how to accomplise the 1000 milisec pause inbetween running the loop down to zero

import java.swing.Timer;
import java.util.Scanner;
import javax.swing.JOptionPane;
import java.awt.event.*;
 
 
public class Time {
	public static void main(String[] args) {
 
	String calculateSecondString = JOptionPane.showInputDialog("Countdown Timer Enter How Many Seconds: ");
 
	int secondsRemaining = Integer.parseInt(calculateSecondString);
 
	while (secondsRemaining > 0) {
		  javax.swing.Timer t = new javax.swing.Timer(1000, new ActionListener() {
          	public void actionPerformed(ActionEvent e) {
				t.start();
				System.out.print("You Have " + secondsRemaining);
				secondsRemaining--;
          	}
       	});
		System.out.print("Zero Seconds Timer Stopped");
		t.stop();
		}
	}
}

If all you wish to do is pause execution, use the Thread.sleep function. If you cannot get this to compile, please post the full compiler error message

This is my last attempt at this. Can anybody tell me if this actually is working properly because I can get this to compile but I cannot get this to run.

import java.util.Scanner;
import javax.swing.JOptionPane;
import javax.swing.Timer;
 
import java.awt.event.*;
 
 
public class Time implements ActionListener{
 
	private int seconds;
	private Timer timer;
	private boolean finished; 
 
	public Time(int seconds) {
		this.seconds=seconds;
		finished=false;
		timer=new Timer(1000, this);
	}
 
	public void start()
	{
		timer.start();
	}
 
 
	@Override
	public void actionPerformed(ActionEvent e) {
		System.out.println("You Have " + seconds);
		seconds--;
		if (seconds==0)
		{
			System.out.println("Zero Seconds Timer Stopped");
			timer.stop();
			finished=true;
		}
		else
			timer.restart();
	}
 
	public boolean isFinished() {
		return finished;
	}
 
	public static void main(String[] args) {
 
		String calculateSecondString = JOptionPane.showInputDialog("Countdown Timer Enter How Many Seconds: ");
 
		int seconds = Integer.parseInt(calculateSecondString);
 
		Time time=new Time(seconds);
		time.start();
		while(!time.isFinished());
 
	}	
}

I need to turn this in today so if somebody can comment on an easier way to do this or make this a little simpler of code than my novice attempt i would appreciate it

I can get this to compile but I cannot get this to run.

How does it "not run"? Any exception thrown? I'd guess the program does run, but you failed to read and absorb what I said in my first response:

A program that doesn't create any GUI components may well terminate before the Timer's first cycle is triggered.

A program that doesn't create any GUI components shouldn't use a javax.swing.Timer.

well I am a very good web traffic monster but my JAVA programming sucks which means when you use terms like GUI the only thing i would be able to tell you is what it stands for because i googled it. This would mean its basically trying to explain to me what a component on a machine in a toothpick factory does because I wouldnt know that either. I only have this problem because I had to retake this course from the Summer which meant that I didnt buy the new edition of this book so none of the timer stuff is in the chapter. I have no idea how to make it run because i cant even read or learn about it in the class im taking.... furthermore I am doing the best I possibly can to absorb hundreds of different "almost" ways of programming using timer I am finding on the internet. I just need this assignment overwith and am williing to pay to have it done. My mac will not run the .class files on any of the programs i have written so im behind another 8 ball at the moment. disaster.

I just need this assignment overwith and am williing to pay to have it done.

I come here to try to help people who want to learn.

Goodbye.
