How to make JTextArea rows and colums auto-increase?

Question

My test program is attached as below.
The JTextArea can not enlarge itself when the text in a line is too long that some characters are hidden.When rows grows too many will also see the problem.
How can I make the rows and columns auto-increase to meet the width or height of my text?
-----My Test Demo----
import java.awt.*;
import java.awt.event.*;
import java.awt.color.*;
import javax.swing.*;
public class Test{
public static void main(String[] args){
JFrame f = new JFrame("My Editor");
Container ct = f.getContentPane();
JPanel jp = new JPanel();
JTextArea ta = new JTextArea("My software.",10,30);
JTextArea ta2 = new JTextArea("Hello,World!",10,30);
jp.setPreferredSize(new Dimension(400,400));
jp.setBackground(Color.green);
jp.setLayout(null);
jp.add(ta);
ta.setBounds(100,100,150,200);
ta.setOpaque(false);
ta.setBorder(null);
jp.add(ta2);
ta2.setBounds(100,120,150,200);
ta2.setOpaque(false);
ta2.setBorder(null);
// jp.addMouseListener(new MyMouseListener());
ct.setLayout(new BorderLayout());
ct.add(jp,BorderLayout.CENTER);
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent evt) {
System.exit(0);
f.setVisible(true);
f.pack();

This link to the Java Swing tutorial will show you how to add the JTextArea to a JScrollPane:

It appears to me that you are new to Swing so you should read the entire tutorial "Creating a GUI using JFC/Swing" before asking any more question. The tutorial can be read online or downloaded from:

The download link for all tutorials on this page is near the bottom.
