JAVA: Save user input as a string in a Jframe GUI

Noob here. I have been browsing for hours, and I still cannot figure out the proper way to get user input to be saved as a string from a text field in my Jframe. Any help would be appreciated. I want to save the user's text into the variable userWords. 

package cipher;
import java.util.*;
import java.io.*;
import javax.swing.*;
import java.awt.*;

public class cipherApp extends JFrame {


    private static final int WIDTH = 700;
    private static final int HEIGHT = 700;      

    private String userWords; // stores user input into a string

    public cipherApp(){
        setTitle("Camo Cipher");
        setSize(WIDTH, HEIGHT);
        setVisible(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);    

    }   
    public static void main(String[] args){
        cipherApp newInstance = new cipherApp();

    }
}

This is a variation of BilaDja's code (I mainly changed the graphics). This will make the window size at around half the screen, in the middle of the screen. If you would like to change the size, change the field 'jf.setSize(x, y);'.

package test;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class Test extends JFrame {

private static final long serialVersionUID = -5624404136485946868L;

String userWord = "";
JTextField userInput;

public Test() {
JFrame jf = new JFrame();
JPanel panel = new JPanel();
JLabel jl = new JLabel("Test");
JButton jButton = new JButton("Click");
userInput = new JTextField("", 30);
jButton.addActionListener( (e) -> {
    submitAction();
});
jf.setSize(500, 500);
jf.setVisible(true);
jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jf.add(panel);
panel.add(jl);
panel.add(userInput);
panel.add(jButton);
}

private void submitAction() {
userWord = userInput.getText();
//do something with the variabe userWord here (print it to the console, etc.)
}

public static void main(String[] args) {
new Test();
}

You have to use a JTextField and a JButton to submit the use input:

public class Test extends JFrame {

    String userWord = "";
    JTextField userInput = new JTextField(10);
    JButton submit = new JButton("Submit");

    public Test() {
        super("Camo Cipher");
        JPanel centerPanel = new JPanel(new FlowLayout(FlowLayout.CENTER, 15, 15));
        setSize(WIDTH, HEIGHT);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setLocationRelativeTo(null); // This center the window on the screen
        submit.addActionListener( (e)-> {
            submitAction();
        });
        centerPanel.add(userInput);
        JPanel southPanel = new JPanel(new FlowLayout(FlowLayout.CENTER, 15, 15));
        southPanel.add(submit);
        Box theBox = Box.createVerticalBox();
        theBox.add(Box.createVerticalStrut(100));
        theBox.add(centerPanel);
        theBox.add(Box.createVerticalStrut(200));
        theBox.add(southPanel);
        add(theBox);
    }

    private void submitAction() {
        // You can do some validation here before assign the text to the variable 
        userWord = userInput.getText();
    }

    public static void main(String[] args) {
        new Test().setVisible(true);
    }
}
