Reading Input From JTextField And Passing It To Another Class

I am having trouble taking user input and passing it to another class as a variable. If I assign the value explicitly (see line 59), it works just fine. What I want to do though, is assign the input from inputField to the variable inputVariable. I tried using:

inputVariable = inputField.getText();

This does not work. Regardless of what is typed into inputField, the output I get is just:

"The user typed "

package example;

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
