title: Increasing/Decreasing Font Size inside textArea using JButton
body: <p>I'm creating a sticky note application using Java.</p>
  
  <p><strong>What I want to do:</strong>
  I want to increase the size of the texts inside <code>textArea</code> each time I click on the increase size.
  I will know how to do the opposite obviously.</p>
  
  <p><strong>Short Code:</strong></p>
  
  <pre><code>        JButton incButton = new JButton("+");
          fontFrame.add(incButton);
          incButton.addActionListener(new fontIncAction());
          JButton DecButton = new JButton("-");
          fontFrame.add(DecButton);
  
          //textArea.setFont( Font("Serif", Font.PLAIN, fz));
      }
  }
  
  private class fontIncAction implements ActionListener{
      public void actionPerformed(ActionEvent e){
  
          textArea.setFont(new Font("Serif",Font.PLAIN,20));
      }
  }
  </code></pre>
