Answer 1

connection is no Class make it Connection
Connection con =
DriverManager.getConnection("jdbc:mysql://localhost:3306/atul","root","password");
Always remember the naming convention of JAVA .The Class names should always start with Capital letter not small letter.So according to this convention the jdk developers are not going to name the class as connection

Answer 2

Increase the scope of Connection variable because again you will face the problem when you will use connection variable in finally block(future).
That is before try block write this.
Connection conn=null;
But in your code you have written connection which has c as small letter. That may be your problem.So make it to
Connection instead of connection
because name of class is always starts with Capital letters coding standards and naming conventions of Java.
So your code become with addition of finally block.
import java.sql.*;
class FirstProgram
{
public static void main(String[] args)
{
Connection con=null;
try
{
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection("jdbc:mysql://localhost:3306/atul","root","password");
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from data");
while(rs.next())
System.out.println(rs.getInt(1)+" "+rs.getString(2)+" "+rs.getString(3));
}
catch(Exception e)
{
System.out.println(e);
}
finally{
con.close();
}
}
}
