After exporting project to jar file, my project is not fully working

i have a problem that in Eclipse when i run my project everything is working fine but when i exporting it last class don't want to open by clicking the button. I'm using database in every class as well as i have referenced library(jcalendar-1.4) if it will help you to solve the problem.
login and registration class are working fine and after logged in and transfer to addActivity class most thing are working like adding everything to database but that one button is unable to open that last class that should show all activities added.
code for AddActivity class and button that is not working in jar file is called txtAddActivity

How to save changes made to an array list in java

I am just a beginner in java coding and I want to know how I can save changes made to an array list through a GUI i have created. This code allows to store data, remove, add, update student information. However it is only temporarily since it is not connected to the hard disk to permanently store this information. I am wondering how I can make this code save the modified information made to it after i close it. I thank you for your time and consideration. The main class code is:
public class StudentDataStorage {
private JFrame frame;
private JTextField textStudentName;
private JTextField textStudentId;
private JTextField textCourseId;
private JTextField textCourseSubject;
void clearFields() {
textStudentName.setText("");
textStudentId.setText("");
textCourseId.setText("");
textCourseSubject.setText("");
}
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
StudentDataStorage window = new StudentDataStorage();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
private ArrayList<Student> arrayList;
private ListIterator<Student> listIterator;

public StudentDataStorage() {

arrayList = new ArrayList<>();
size = 0;

You could write a Thread changing the color of your component as needed, eg :
class Effect extends Thread {
public void run() {
try {
while (true) {
yourLabel.setForeground(new Color(aValue, bValue, cValue)); // you can apply coloring logic
Thread.sleep(500); //sleep for 0.5 secs , so your color changes twice every second
}
} catch (InterruptedException e) {
}
}
}

add dynamic checkbox in java windowbuilder

I want to add a dynamic checkbox after selecting an item in combo box.
I am working on eclipse and design my frame on window builder.
final JComboBox<String> comboBox = new JComboBox<String>();
comboBox.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String typeName = comboBox.getSelectedItem().toString();
for (int i = 0; i < SqlQuery.getCoursesName(typeName).size(); i++) {
JCheckBox c = new JCheckBox(SqlQuery.getCoursesName(typeName).get(i));
c.setVisible(true);
coursePanel.add(c);
frame.repaint();
frame.validate();
System.out.println(c.getText());
}
}
});
comboBox.setBounds(208, 221, 91, 20);

Hope you understand what I wrote. I want to show a list of coursesName after click on the comboBox.
Why the frame does'nt show the checkbox?
Thank you.

First and foremost. The comboBox.setBounds() is a very bad practice. Take some time and see Layout Managers. Also add 'swing' tag in your post since you are referring to Swing library.
The frame doesn't show the component because you repaint the wrong one. You add the checkbox in coursePanel, which means you have to repaint() & revalidate() coursePanel. So coursePanel.repaint() instead of frame.repaint() will help you.
Also checkBox.setVisible(true)is not required, since checkBox is visible by default.
Finally i have added the way of how i would do it.

Another option is to create the checkbox as a field outside of the actionlistener (like i did) and set its bounds with window builder and use setVisible(false). Then on your listener, setVisible(true)

how to read from text file to labels

so i have program that need save to file and then read from it, i already have read from text file that works but i cant get read from the file working, i had it static before but teacher does not like it and make me to change it to read from file. i never used gui before and the only stuff what he show us in gui is how to place a button and text field.
