Hi Friend,

Try the following code:

import java.io.*;
import java.sql.*;
import java.util.*;

class InsertToFile {
    private static void writeToFile(java.util.List<String> list, String path) {
        BufferedWriter out = null;
        try {
            File file = new File(path);
            out = new BufferedWriter(new FileWriter(file, true));
            for (String s : list) {
                out.write(s);
                out.newLine();
            }
            out.close();
        } catch (IOException e) {
        }
    }

    public static void main(String arg[]) {
        java.util.List<String> list = new ArrayList<String>();
        try {
            Connection con = null;
            Class.forName("com.mysql.jdbc.Driver");
            con = DriverManager.getConnection(
                    "jdbc:mysql://localhost:3306/register", "root", "root");
            Statement st = con.createStatement();
            ResultSet rs = st.executeQuery("Select * from student");
            while (rs.next()) {
                list.add(rs.getString(1) + "  " + rs.getString(2) + "  "+ rs.getString(3) + "  " + rs.getString(4));
            }
            writeToFile(list, "student.txt");
        } catch (Exception e) {
        }
    }
}

Thanks

I getting this type error

Exception in thread "main" java.lang.NoClassDefFoundError:InsertToFile

tanks you sir

Hi Friend,

It seems that you have saved the file with another name. Check your code whether the class name defined in the code and name through which the file is saved, are same?

Thanks
