  public JTableComponent(){
  JFrame // Establish the frame.
  frame = new JFrame("title");
  frame.setLayout(new BoxLayout(frame.getContentPane(), BoxLayout.Y_AXIS));
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  frame.setPreferredSize(new Dimension(700, 700));

  // Establish button dimensions.
  Dimension buttonDimension = new Dimension(120, 120);

  // Establish Textfield dimensions.
  Dimension textDimension = new Dimension(110, 110);


  // Create an input text field.
  JTextField textInput = new JTextField(20);
  textInput.setPreferredSize(textDimension);
  textInput.setMinimumSize(textDimension);
  textInput.setMaximumSize(textDimension);
  textInput.setHorizontalAlignment(JTextField.CENTER);
  JPanel  panel = new JPanel();
  panel.add(textInput);
  String string = textInput.getText();

  frame.pack();
  frame.setLocationRelativeTo(null);
  frame.setVisible(true);
  frame.add(textInput);
