Navigate Data using Java Swing

In this java tutorial section, you will learn how to navigate the Database data using Java Swing. For this, we have created a form with four buttons to perform an action. Through these buttons, we have allowed the user to get the first , last , next and previous records.

Here is the code of NavigateData.java:

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

public class NavigateData extends JFrame{
    JTextField text1,text2,text3,text4;
  JLabel label1,label2,label3,label4;
  int count=0;
  JButton nextRecord,previousRecord,firstRecord,lastRecord;
    static JPanel panel;
  public static void main(String []args)throws Exception{
     NavigateData navigate=new NavigateData();
   navigate.setSize(350,200);
    navigate.setVisible(true);
    navigate.add(panel);
  }
public NavigateData(){
  text1=new JTextField();
  text2=new JTextField();

  text4=new JTextField();
  label1=new JLabel("Employee ID");

panel=new JPanel(new GridLayout(6,2));
panel.add(label1);
panel.add(text1);

panel.add(text2);
panel.add(label3);
panel.add(text3);
