All you have to do is to read that text file when your program starts. Read the file and put the contents into the text box

Let me clear what you want to say,
You have a TEXT BOX, and you have some text it in lets say MR. KURD, Now when I close that app and run it again, you want the textbox to have MR. KURD in it? Is that what you want?

Create a function that would read the text file, now run that function when your program has initialized. You can put that function in the constructor of your application.

It's the same that I gave you previously, https://docs.oracle.com/javase/tutorial/essential/io/file.html
Code:
try (BufferedReader reader = Files.newBufferedReader(file)) {
String line = null;
while ((line = reader.readLine()) != null) {
JTextField.setText(line); //Put the text content in your text field
}
} catch (IOException x) {
System.err.format("IOException: %s%n", x);
}This code assumes that you only have one line in the text file, you'll have to modify it if it is to contain more data
