How do i get multiple double inputs separated by ; from one JtextField and store them on an array?

I have this problem in JAVA where I need to take multiple doubles separated by; from a single jTextField and store them into an array each time I click save button, I also want to set a limit of 5 inputs for example :
12;13;14;15;16 into my jtextfield and then I want it to stop until I click on save and then it became blank and so on
Sorry if I wasn't clear enough it's my first time here and I'm still a beginner in JAVA.
Thanks in advance!
Here is my actual code at the moment, nothing great

you can take the JTextField text with getText() method and then you can tokenize this string with StringTokenizer st = new StringTokenizer(textField.getText(),";"). Then you can store every char between ";" with
int i=0;
while (st.hasMoreTokens()) {
array[i] = st.nextToken();
i++;
}
Remember that a size of an array is static and defined when the array is declared and initialized. You can use other data structure, such as an ArrayList<T>.
I hope that this is what you want.

As I already stated in my comment, you need to read the article about concurrency in Swing. To solve your freezing problem you need to move your code that calls database operations in another thread. The best way to do it is to use SwingWorker. Here is how it will look in your code
private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
String sql = "INSERT INTO tbStudent VALUES ('"+txtNIS.getText()+"','"+txtName.getText()+"','"+txtAddress.getText()+"','"+txtEmail.getText()+"','"+txtJurusan.getText()+"')";
java.sql.Connection conn=(Connection)connection.configDB();
java.sql.PreparedStatement pst = conn.prepareStatement(sql);
SwingWorker<Boolean, Void> worker = new SwingWorker<Boolean, Void>() {
private String message;
#Override
protected Boolean doInBackground() throws Exception {
try {
return pst.execute();
} catch (Exception e) {
message = e.getMessage();
return false;
}
}
#Override
protected void done() {
if (get()) {
JOptionPane.showMessageDialog(null, "Sukses menambahkan data");
} else {
JOptionPane.showMessageDialog(menu.this, message);
}
}
};
worker.execute();
}
I've not tested this solution. If it doesn't work, please let me know.

How to "save" my program?

Hi guys I'm currently working on a kind of "dungeon crawler" game and i need some help with saving my program. I would like for my jFrame to save(all of my entered text)so that when i close the program and open it back up from my Desktop it will have my entered text and everything i have changed still in the program. I'm confused as to how to save and am hoping for some help. Thanks ahead of time for all of your time, anwsers, links, examples, and advice. To be clear i am new to this and only have been coding for about 5 days now and i still use the Netbeans jFrame "Design" feature to generate most of the code for me. Below I've posted the code for my second Jframe. Feel free to copy and paste this code in your netbeans IDE. Thanks :).
NOTE: in case needing the names for my other Jframes.
"Character" is my second jFrame
"MainClass" is my java app
"MainGamePanel" is my third JFrame
NOTE:some buttons may not work because this is not all of my jFrames
package ddsheet; //This is the code for my jFrame named Character
import java.nio.file.Files;
import javax.swing.JFileChooser;
public class Character extends javax.swing.JFrame {
public Character() {
initComponents();
}

another idea is create a separate class containing all the information you need to save.
And use the class as an object in your main class and then save the object like this.
Look into serializing a class (this is called serialization).
public class GameState implements Serializable{
...//game settings and states stored here
}
//inside the main running class
my_settings = GameState();
...
// write object
FileOutputStream fos = new FileOutputStream(path..);
ObjectOutputStream out = new ObjectOutputStream(fos);
out.writeObject( my_settings );
out.close();
fos.close();
//read object
fis = new FileInputStream(path..);
ObjectInputStream ois = new ObjectInputStream(fis);
my_settings = (GameState) ois.readObject();
ois.close();

xml mabye?
I think you may be able to use a FileOutputStream and PrintWriter to create an xml file with data nodes keeping data of the state of everything in the game. to read it back, you might want to use Simple API for XML (SAX). Just an idea.
