Hi Friend,

Try the following code:

import java.io.*;
import java.awt.*;
import java.sql.*;
import javax.swing.*;
import java.awt.event.*;
import java.awt.image.*;
import javax.imageio.ImageIO;

public class Images {
File file;

JFrame f = new JFrame("Frame in Java Swing");
f.getContentPane().setLayout(null);
final JTextField text = new JTextField("", 20);

JLabel JLabel1 = new JLabel("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n TEXTURE FEATURES \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n",JLabel.CENTER);
JLabel JLabel4 = new JLabel(" Energy ");
final JTextField val1= new JTextField("",30);

final JTextField val4= new JTextField("",30);
JLabel JLabel6 = new JLabel(" Contrast ");
final JTextField val5= new JTextField("",30);
JLabel JLabel7 = new JLabel(" Homogenity ");
final JTextField val6= new JTextField("",30);
JLabel JLabel8 = new JLabel(" Correlation ");
final JTextField val7= new JTextField("",30);
JLabel JLabel2 = new JLabel("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n COLOR FEATURES \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n ",JLabel.CENTER);

f.setVisible(true);
Button1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){

final int returnVal = chooser.showOpenDialog(null);

String path=file.getPath();
text.setText(path);
l.setIcon(new ImageIcon(path));
}
}
});

continue..

Button2.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
String feature1 = val1.getText();
String feature4 = val4.getText();
String feature5 = val5.getText();
String feature6 = val6.getText();
String feature7 = val7.getText();
String feature2 = val2.getText();
String feature3 = val3.getText();
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/register";, "root", "root");
PreparedStatement st = con.prepareStatement("insert into enhancement values(?,?,?,?,?,?,?,?)");
FileInputStream fis = new FileInputStream(file);
st.setString(1,feature1);
st.setString(2,feature4);
st.setString(3,feature5);
st.setString(4,feature6);
st.setString(5,feature7);
st.setString(6,feature2);
st.setString(7,feature3);
st.setBinaryStream(8, (InputStream)fis, (int)(file.length()));
int s = st.executeUpdate();
JOptionPane.showMessageDialog(null,"Data is successfully inserted.");
}
catch(Exception ex){}
}
});
}
public static void main(String args[]) {
Images img=new Images();
}
}
class ImageFileFilter extends javax.swing.filechooser.FileFilter {
public boolean accept(File file) {
if (file.isDirectory()) return false;
String name = file.getName().toLowerCase();
return (name.endsWith(".jpg") || name.endsWith(".png")|| name.endsWith(".gif"));
}
public String getDescription() { return "Images (*.gif,*.bmp, *.jpg, *.png )"; }
}

For the above code, we have created database table enhancement:

CREATE TABLE `enhancement` (
`Energy` varchar(255) default NULL,
`Entropy` varchar(255) default NULL,
`Contrast` varchar(255) default NULL,
`Homogenity` varchar(255) default NULL,
`Correlation` varchar(255) default NULL,
`typ_string2` varchar(255) default NULL,
`typ_string3` varchar(255) default NULL,
`image` longblob
)

Thanks
