Here is your required code.

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

class CheckConnection{
  public static void main(String arg[]){
    JFrame frame=new JFrame();

    JLabel label1 = new JLabel();
    label1.setText("Enter Database Name:");
    final JTextField text1 = new JTextField(20);

    JLabel label2 = new JLabel();
    label2.setText("Enter Mysql Password:");
    final JPasswordField text2 = new JPasswordField(20);

    JButton button=new JButton("submit");
    JPanel 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 ae){
    String database=text1.getText();
    String pass=text2.getText();
    try{
    Class.forName("com.mysql.jdbc.Driver").newInstance();
            Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/"+database, "root", pass);
            Statement st=conn.createStatement();
            ResultSet rs=st.executeQuery("Select * from data");
            while(rs.next()){
             System.out.println(rs.getString("name")+" "+rs.getString("address"));
            }
            }
    catch(Exception e){
