java.sql.SQLException: No database selected – why?

Firstly, I am considering my answer to show you another better way for connection with MySQL Database, it’s much easier and less nu-expected Exception(s).
You need to do some steps:

1. Download Connector/J and add it to your class path(if you are using an IDE there is add the .jar to the library, or there is many tuts on YouTube).
2. Create your database in your MySQL program.
3. See this example below example below I made for you demonstrates how to connect and execute queries on MySQL : import java.sql.*; public class MySqlConnection { private String MYSQL_DRIVER = "com.mysql.jdbc.Driver"; private String MYSQL_URL = "jdbc:mysql://localhost:3306/test"; private Connection con; private Statement st; private ResultSet rs; public MySqlConnection() { try { Class.forName(MYSQL_DRIVER); System.out.println("Class Loaded...."); con = DriverManager.getConnection(MYSQL_URL,"",""); System.out.println("Connected to the database...."); st = con.createStatement(); int c =st.executeUpdate("CREATE TABLE Accounts (Name VARCHAR(30))"); System.out.println("Table have been created."); System.out.println(c+" Row(s) have been affected"); con.close(); } catch(ClassNotFoundException ex) { System.out.println("ClassNotFoundException:\n"+ex.toString()); ex.printStackTrace(); } catch(SQLException ex) { System.out.println("SQLException:\n"+ex.toString()); ex.printStackTrace(); } } public static void main(String...args) { new MySqlConnection();
