If you only have one String to pass, add it to the constructor of your second JFrame:

public class SecondFrame extends JFrame {
    public SecondFrame(String someValueFromFirstFrame) {
        someTextField.setText(someValueFromFirstFrame);
    }
}

and pass it when creating the second JFrame:

SecondFrame secondFrame = new SecondFrame(firstTextField.getText());

---

If there is more than one attribute to pass, consider putting them together in another class and pass the instance of this class. This saves you from changing the constructor every time you need to pass an additional variable.

---

Simply add some reference to the first frame in the second or pass the value you're interested in to the second frame before you display it.

As for the code example you requested:

public class SecondFrame extends JFrame {
    private JFrame firstFrame;

    public SecondFrame(JFrame firstFrame) {
        this.firstFrame = firstFrame;
    }
}

Now you can obtain everything there is to obtained from the firstFrame through the internal reference to it.
