[VinTiger]

My text area in this program I'm working on is not visible, only the buttons are....any help appreciated.

import java.awt.Dimension;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.*;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;


public class MyText extends JFrame {

    private Toolkit toolkit;


public static int LineCount = 0; //Counts the lines.
   public static String[] content;  
   
   public static void ReadFile() throws Exception { 

      BufferedReader TextFileReader = new BufferedReader(new FileReader("./info.txt")); 

      String c;
      String t;

      t = "Blank";
      while((c = TextFileReader.readLine()) != null) {  
         LineCount++;
         t += ","+ c;
      }

      t = t.replaceAll("Blank,",""); 
      content = new String[LineCount];
      content = t.split(",");
      TextFileReader.close(); 
      
      
      for(int i = 0; i < 7; i++)  //Keep printing as long as i is smaller than 7, which is what I need for my text file.
          System.out.println(content[i]); //prints the first part of my list of names.
         
   }


    public MyText() {

        setTitle("Name and Address");
        setSize(300, 400);

        toolkit = getToolkit();
        Dimension size = toolkit.getScreenSize();
        setLocation((size.width - getWidth())/2, (size.height - getHeight())/2);
        setDefaultCloseOperation(EXIT_ON_CLOSE);

        JPanel panel = new JPanel();
        getContentPane().add(panel);

	panel.setLayout(null);


        JButton beep = new JButton("Next");
        beep.setBounds(150, 60, 80, 30);
        beep.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent event) {
                toolkit.beep();
for(int i = 0; i > 0; i++)
System.out.println(content[i]);


            }
        });

       JButton close = new JButton("Back");
       close.setBounds(50, 60, 80, 30);
       close.addActionListener(new ActionListener() {
           public void actionPerformed(ActionEvent event) {
               toolkit.beep();

for(int i = 0; i > 0; i--)
System.out.println(content[i]);

          }
       });

        panel.add(beep);
        panel.add(close);

    }

    public static void main(String[] args) {

        MyText buttons = new MyText();
        buttons.setVisible(true);

    }
}

You have no text that should be displayed in the GUI. Use JLabels and/or JTextAreas to display text in a GUI.

JTextArea is much better. So in future you can do any formatting and processing easily than the button.

First of all you have to add all the components in the panel. So you may want to look at the layouts as well.

I think that JLabel may actually work better if you don't need the text to be user-editable. JTextAreas do not allow text alignment and are actually have very little in the way of formatting capabilities. If you use a JLabel you can just use html new-line tags. (Both <br> and <p> create new lines, but I believe you would use <br> to force new line, and <p> for possible new line.)

My take on it is that unless you need user-editable text, use a JLabel as it allows text alignment.

Yes Singing, it's depends on the requirement of our thread starter.

Or else, you can use setEditable(false) to disable the content edit on the JTextArea. Still you can copy the content and selectable, but cannot change the content.
