Getting And Setting Frame Name From Another Class

package com.simbaorka101.te.gui;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.ScrollPaneConstants;
import javax.swing.event.DocumentListener;

[code]....

This is my frame class, now I want to be able to change the name of the frame, and get the name with frame.getName() in another class. But I'm not sure how to do this, i tried making a new frame in that class but i feel it's just another frame and not the one i made, also tried something like

public JFrame getFrame(){
this.getFrame();
}

and few variations but it was wrong.
