title: How to show a variable value in JLabel
body: <p>I am new to Java programming. I want to show the value of my variable in the output window not in the console view.
  Here comes the code:</p>
  
  <pre><code>import java.awt.BorderLayout;
  
  import javax.swing.JFrame;
  import javax.swing.JLabel;
  import javax.swing.SwingConstants;
  
  public class ShowAFrame {
  
      public static void main(String[] args) {
  
          // Variables in this code
          int one = 12;
          int two = 22;
          int total = one + two;
          System.out.println(total);
  
          JFrame myFrame = new JFrame("Test GUI");
          myFrame.setVisible(true);
          myFrame.setBounds(300, 200, 700, 400);
          JLabel myText = new JLabel("I'm a label in the window",
                  SwingConstants.CENTER);
          myFrame.getContentPane().add(myText, BorderLayout.CENTER);
  
      }
  
  }
  </code></pre>
