title: What is import com.mysql.jdbc.Driver;
body: <p>As part of my project I am trying to connect it with database. I searched in google for the code and I got the following code. In that I don't understand 2 things - "import com.mysql.jdbc.Driver;" and "new Driver". What do these 2 mean ?</p>
  
  <pre><code>package javasql;
  
  import com.mysql.jdbc.Driver;
  import java.sql.*;
  
  public class Connect {
  public Connect() throws SQLException{
      makeConnection();
  } 
  
  private Connection koneksi;  
  
   public  Connection makeConnection() throws SQLException {
      if (koneksi == null) {
           new Driver();
          // buat koneksi
           koneksi = DriverManager.getConnection(
                     "jdbc:mysql://localhost:3306/mysql","root","virus");
       }
       return koneksi;
   }  
  
   public static void main(String args[]) {
       try {
           Connect c = new Connect();
           System.out.println("Connection established");
       }
       catch (SQLException e) {
           e.printStackTrace();
           System.err.println("Connection Failure");
       }  
  
  }
  }
  </code></pre>
  
  <hr>
  
  <pre><code>package javasql;
  
  import java.sql.*;
  
  public class SqlStatement {
  private Statement statement;
  public SqlStatement() throws SQLException{
      makeStatement();
  }
  public Statement makeStatement() throws SQLException{
      Connect c = new Connect();
      Connection conn = c.makeConnection();
      statement = conn.createStatement();
      return statement;
  }
  public void insert(String name,int npm)throws SQLException{
      statement.execute("insert into Student values(\""+name+"\","+npm+");");
  }
  public static void main(String arg[]){
      try {
          SqlStatement s = new SqlStatement();
          s.insert("Ferdi2",3);
          s.insert("Anca2",3);
          System.out.println("Success");
      }
      catch(SQLException e){
          System.out.println("Failed");
          e.printStackTrace();
      }
  }
  }

  <p>I use NetBeans IDE to develop my project. When I used these codes I made it as a new project. Then it worked fine. But whenever I tried to include these codes in another projects errors are showing at "import com.mysql.jdbc.Driver;". Why is it so ? Can I use these 2 codes in another projects ?</p>
