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

[Mr.Kurd]

when i up a program i type for eg"Mr.Kurd" in a textField, i want when i click on command save it and when i close it and reup it showing me "Mr.Kurd" in the.textFild.

[Ex094]

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?

[Mr.Kurd]

Yes Yes, You Are Really Really clever.

[Ex094]

Then this is what you have to do

Code:

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

[Mr.Kurd]

let's Say when i up a program nothink in TextBox, But i type Mr.Kurd and when i click save command save a Text for me & i wan't when i close it and reup it textBox content Mr.Kurd.

[Ex094]

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.

[Mr.Kurd]

Can write a code. Sorry i tired you.

i have new question how i use java with web service i :
GET
POST

[Ex094]

It's the same that I gave you previously, https://docs.oracle.com/javase/tutorial/.../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
