Go4Expert - java practice for beginger

Here I am trying to give you a tutorial about how to insert value to the database using java.

Code:

import java.sql.*;



public class InsertValues{

 public static void main(String[] args) {

 System.out.println("Insert the values to database table!");

  Connection con = null;

  String url = "jdbc:mysql://localhost:3306/";

  String db = "jdbctutorial";

  String driver = "com.mysql.jdbc.Driver";

  try{

  Class.forName(driver);

  con = DriverManager.getConnection(url+db,"root","root");

  try{

  Statement st = con.createStatement();

  int val = st.executeUpdate("INSERT employee VALUES("+13+","+"'Aman'"+")");

  System.out.println("1 row affected");

  }

  catch (SQLException s){

  System.out.println("SQL statement is not executed!");

  }

  }

  catch (Exception e){

  e.printStackTrace();

  }

  }

}
