Question

I have two java classes. One is NewFrame.java where the forms(buttons, textfields) are located. And the other one is Main.java where I have put the connection string for mysql:

Main.java looks like this:

public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) throws Exception {
        // TODO code application logic here
        Class.forName("com.mysql.jdbc.Driver");
        Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/employee_record", "root", "password");
        PreparedStatement statement = con.prepareStatement("select * from employee");
        ResultSet result = statement.executeQuery();

    }

}

How do I inherit from the main.java so that the declarations in it would be universally accessible to the forms in NewFrame.java?
Please help. Thanks

A better way to solve it is to create a utility class

public class DataBaseHandler{
  public static Connection getConnection(){
     //...
  }

  public static Object executeQuery(String query){
     //...
  }
}
