title: Multiple line JTextPane
body: <p>So I have been starting to work on an encyclopedia as a project for college and I'm coming over an issue. I am trying to import a .txt file to print my text to my text panel but the problem is, I can't print paragraphs and it only prints one line.
  My textpanel code is the following:</p>
  
  <pre><code>import java.io.*;
  import javax.swing.JPanel;
  import javax.swing.JButton;
  import javax.swing.ImageIcon;
  import javax.swing.JLabel;
  import javax.swing.JTextArea;
  
  
  public class GTAIntro extends JPanel {
  private static final long serialVersionUID = 1L;
  
  public GTAIntro() {
      setSize(800,800);
      setLayout(null);
  
      JButton button_1 = new JButton("");
      button_1.setIcon(new ImageIcon("D:\\Facultate\\anul 2\\Java Workspace\\Encyclopedia\\src\\icons\\back.png"));
      button_1.setEnabled(false);
      button_1.setBounds(10, 700, 50, 50);
      add(button_1);
  
      JButton button = new JButton("");
      button.setIcon(new ImageIcon("D:\\Facultate\\anul 2\\Java Workspace\\Encyclopedia\\src\\icons\\next.png"));
      button.setBounds(740, 700, 50, 50);
      add(button);
  
      JLabel rockstarlogo = new JLabel("");
      rockstarlogo.setIcon(new ImageIcon("D:\\Facultate\\anul 2\\Java Workspace\\Encyclopedia\\src\\icons\\gta\\rockstar-logo.png"));
      rockstarlogo.setBounds(10, 11, 150, 150);
      add(rockstarlogo);
  
      JTextArea textpanel = new JTextArea();
      textpanel.setLineWrap(true);
      textpanel.setWrapStyleWord(true);
      textpanel.setEditable(false);
      try{
          FileInputStream fstream = new FileInputStream("D:\\Facultate\\anul 2\\Java Workspace\\Encyclopedia\\src\\text\\gta\\gtaintro.txt");
          DataInputStream in = new DataInputStream(fstream);
          BufferedReader br = new BufferedReader(new InputStreamReader(in));
          String strLine;
          while((strLine = br.readLine()) != null) {
              textpanel.setText(strLine);
          }
      in.close();
      }catch(Exception e){System.err.println("Error: " + e.getMessage());}
      textpanel.setBounds(100, 222, 593, 528);
      add(textpanel);
  
  }
  }
