Answer: 
Download "mysql-connector-java-5.1.13-bin.jar" from following link <http://sqlworkbench.mgm-tp.com/viewvc/trunk/sqlworkbench/junit/mysql-connector-java-5.1.13-bin.jar?revision=2294&pathrev=2294>

Following is a sample java code to connect to a mysql database and retrieve data from a table.

In below code database name is "databaseName"

and table name is "userTable"

Dont forget to add "mysql-connector-java-5.1.13-bin.jar" to your netbeans project's libraries.

```
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class NewClass {

public static void main(String[] args) {

    Connection conn = null;

    String url = "jdbc:mysql://127.0.0.1:3306/";
    String dbName = "databaseName";
    Statement stmt = null;
    ResultSet result = null;
    String driver = "com.mysql.jdbc.Driver";
    String databaseUserName = "root";   //user name to connect to database(plz change it with your mysql username)
    String databasePassword = "root";   //password to connect to database(plz change it with your mysql password)
    try {
        Class.forName(driver).newInstance();
        conn = DriverManager.getConnection(url + dbName, databaseUserName, databasePassword);
        stmt = conn.createStatement();
        result = null;
        String password,username;
        result = stmt.executeQuery("select * from userTable ");
        if(!result.isBeforeFirst()){
            System.out.println("resultset contin no rows");
        }else{ // result set contain some data.... ie.. table contain some rows
            // process data
        }

        conn.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
}
