Hi Friend,

Try the following code:

import java.awt.*;
import java.sql.*;
import javax.swing.*;
import java.awt.event.*;

public class SearchWord extends JFrame{
JTextField text1,text2;
JLabel label1,label2;
JButton button;
static JPanel panel;
JTextArea area;
JScrollPane pane;
public SearchWord(){
text1=new JTextField(10);
label1=new JLabel("Enter word");
text2=new JTextField(10);
label2=new JLabel("Enter Description");
button=new JButton("Submit");
panel=new JPanel(new GridLayout(3,2));
panel.add(label1);
panel.add(text1);
panel.add(label2);
panel.add(text2);
panel.add(button);
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
String word = text1.getText();
String description = text2.getText();
Connection con = null;
String url = "jdbc:mysql://localhost:3306/";;
String db = "test";
String driver = "com.mysql.jdbc.Driver";
String user = "root";
String pass = "root";
try{
Class.forName(driver);
con = DriverManager.getConnection(url+db, user, pass);
Statement st = con.createStatement();
ResultSet rs=st.executeQuery("select * from search where word='"+word+"'");
String w="";
if(rs.next()){
w=rs.getString(2);

}
if(word.equals(w)){
System.out.println(w);
JOptionPane.showMessageDialog(null, "Word already exist.");
}
else{

int i=st.executeUpdate("insert into search(word,description) values('"+word+"','"+description+"')");
JOptionPane.showMessageDialog(null, "Word is successfully added");
}

rs.close();
}
catch(Exception ex){}
}
});
}
public static void main(String[]args){
SearchWord search=new SearchWord();
search.add(panel);
search.setVisible(true);
search.setSize(300,100);
}
}

Thanks
