Multiple queries with 1 connection

Question

Can I execute multiple queries with one connection?
//Example -
<%
String firstconn;
Class.forName("org.gjt.mm.mysql.Driver");
// create connection string
firstconn = "jdbc:mysql://localhost/profile?user=mark&password=mstringham";
// pass database parameters to JDBC driver
Connection aConn = DriverManager.getConnection(firstconn);
// query statement
Statement firstSQLStatement = aConn.createStatement();
String firstquery = "UPDATE auth_users SET last_log='" + rightnow + "'WHERE name='" + username + "' ";
// get result code
int firstSQLStatus = firstSQLStatement.executeUpdate(firstquery);
// close connection
firstSQLStatement.close();
%>     
Now, instead of building a new connection for each query, can I use the same connection info for another query?
if so - how do you do this?
thanks for any help.

Create multiple statement objects from your connection. It's a good idea to close these in a finally block after you're done with them
Connection conn = null;
Statement stmt1 = null;
Statement stmt2 = null;
try {
    conn = DriverManager.getConnection();
    stmt1 = conn.createStatement();
    // some sql here
    stmt2 = conn.createStatement();
    // some more sql here
} finally {
    if ( stmt1 != null ) stmt1.close();
    if ( stmt2 != null ) stmt2.close();
