How can I add a counter for when I click a button, so I can use it to know what file line to write to?

I am very new to Java, but I'm using it for a school project to make a student tracker. I'm just starting with the layout, and am adding students to a file right now. On line 138, I need a way to add a counter every time I click the add button.

I tried to name a variable and use a++, but I can't use it and keep adding since it's accessed within an inner variable. If I initiated it inside, then it would initiate it back every time i clicked the button.

Edit: As noted in the comments, Swing is single threaded so thread safety is not a concern with this solution. Nonetheless, using an AtomicInteger here is still an effective way of maintaining the click count from this anonymous class. A class member in the containing class would be a better solution but this is executed from a static context so I hesitate to suggest that.
AtomicInteger atomicInteger = new AtomicInteger(0);
addButton.addActionListener(new ActionListener(){
#Override
public void actionPerformed(ActionEvent e) {
try {
NameFileWriter.append(addNameField.getText());
NameFileWriter.close();}
catch (IOException ignored) {}
try {
GradeFileWriter.append(addGradeField.getText());
GradeFileWriter.close();}
catch (IOException ignored) {}
// Way to count how many students there are, to write to correct line in files
// Every time this statement is called, one is added
// to the total and the total is returned
int totalClicks = atomicInteger.addAndGet(1);
}
});

How can I transfer data between one jframe to another jframe?

I'm new to java and for some reason I don't know any other way to transfer the data from another frame after pressing submit. For example, it will show the output frame the label and textfield that the user wrote in the first frame like this "Name: "user's name". If you do know please post the code I should put, thank you!

It's not clear what problem you are having displaying a value from one field in another frame. But here's an example of doing that (with fields reduced to just one for demonstration):
public class EventDriven extends JFrame {
private final JTextField nameField = new JTextField(15);
private final JButton submit = new JButton("Submit");
private final JButton clear = new JButton("Clear All");
public EventDriven() {
setTitle("Input");
setLayout(new FlowLayout(FlowLayout.CENTER));
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
add(new JLabel("Name: "));
add(nameField);
submit.addActionListener(this::showOutput);
add(submit);
clear.addActionListener(this::clearInput);
add(clear);
pack();
}
private void showOutput(ActionEvent ev) {
submit.setEnabled(false);
JDialog output = new JDialog(EventDriven.this, "Output", true);
output.add(new Label("Name: " + nameField.getText()), BorderLayout.CENTER);
JButton okButton = new JButton("OK");
output.add(okButton, BorderLayout.SOUTH);
okButton.addActionListener(bv -> output.setVisible(false));
output.pack();
output.setVisible(true);
}
private void clearInput(ActionEvent ev) {
nameField.setText(null);
submit.setEnabled(true);
}
public static void main(String[] args) {
EventDriven window = new EventDriven();
window.setVisible(true);
}
}
You will also see that I've simplified your action listeners to demonstrate an easier way to respond to user driven event.s

I am getting an error when im trying to write a code to automatically select a tab from tabbed pane when condition is true, but im getting an error with null pointer exception in while im trying to execute the code after compiling it!!

In the constructor you are initializing a local JTabbedPane and not the one that is declared in the class and accessed in the method loadData.
Please initialize the variable tab in a proper way, i.e.
this.tab=new JTabbedPane();
instead of
JTabbedPane tab=new JTabbedPane();

Why doesn't the south part for the border layout show up?

I've tried different methods to fix this, but apparently nothing works. Because I am new to java I actually don't know if there's something wrong with my code.
I've tried setting the size of the text area that is supposed to go into the SOUTH part of the border layout, but the size is still to small to see.
Anyone know of a solution?

change this

or this
pane.getViewport().add(results, null);
use setViewportView or getViewport().add to set component to jscrollpane.also you can pass component (jtextarea ) to constructor of jscrollpane.read more about jscrollpane here

JPanel - positioning element

I have a problem with setting position for one of the elements (the image). I cannot align it to right-bottom of the screen. I tried to use different layouts but I can't make it to work exactly like I want it.
Below is the url to view how it looks now. The image is in the right-bottom but it's a new BorderLayout and it creates extra space on the bottom so I would prefer it to fit with the rest. Red square shows where image should be placed.
Below is the code of my program:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import java.util.*;
public class Server extends JFrame implements ActionListener{

}

}

if(e.getSource() == exit){
super.dispose();
}
if(e.getSource() == reset){

while(true){

messages.setText(messages.getText() + received +

new OutputStreamWriter(sock.getOutputStream());
BufferedWriter bw = new BufferedWriter(out);
bw.write(received);
bw.flush();
}
}catch(Exception e){

}
}
}

This should do the trick. It just needed some more panels to constrain the 2nd image (160x160px) to the PAGE_END and LINE_END of some BorderLayout instances.

You should organize the structure of your code better. The constructor is typically found at the start of the class.
Instead of having 3 methods to create the GUI components you could probably have one. You don't need to use the getContentPane() method. When you use the add(...) method of a JFrame the components are added to the content pane. I would also use a JTextArea to display message. a JEdtitorPane should only be used for HTML. You also should add the text area to a JScrollPane so scrollbars will appear as more messages are added.
So the basic code would be something like:
JTextArea textArea = new JTextArea(20, 50);
JScrollPane scrollPane = new JScrollPane( textArea );
add(scrollPane, BorderLayout.CENTER);
JPanel east = new JPanel( new BorderLayout() );
east.add(menuPanel, BorderLayout.NORTH);
east.add(logo, BorderLayout.SOUTH);
add(east, BorderLayout.EAST);
