Please Help Resolve a Code Bug
Any good samaritans out there with a spare 5 minutes?
Complete noob here, and I'm working on an assignment for a beginner Java course. Last week we made a simple Hello Server web program. This week we're editing last week's code to make a add() and display Calendar app.
Below is the entire code. It compiles and runs but instead of the current date minus/plus the input number the program returns...
Quote:
New Calendar Date, java.util.GregorianCalendar[time=1334343283825,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneIn fo[id="America/Chicago",offset=-21600000,dstSavings=3600000,useDaylight=true,transitions=235,lastRule=java.util.SimpleTimeZone[id=America/Chicago,offset=-21600000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDa yOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=72 00000,endTimeMode=0]],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2012,MONTH=3,WEEK_OF_YEAR=15,WEEK_OF_MONTH=2,D AY_OF_MONTH=13,DAY_OF_YEAR=104,DAY_OF_WEEK=6,DAY_OF_WEEK_IN_MONTH=2,AM_PM=1,HOUR=1,HOUR_OF_DAY=13,MI NUTE=54,SECOND=43,MILLISECOND=825,ZONE_OFFSET=-21600000,DST_OFFSET=3600000]!

So with further adieu the code:
Code:
import java.io.*;
import java.util.*;
import java.text.SimpleDateFormat;
/**
* An example of subclassing NanoHTTPD to make a custom HTTP server.
*/
public class HelloServer extends NanoHTTPD
{
public HelloServer() throws IOException
{
super(8080, new File(".").getAbsoluteFile());
}
public Response serve( String uri, String method, Properties header, Properties parms, Properties files )
{
System.out.println( method + " '" + uri + "' " );
String msg = "<html><body><h1>Calendar Offset</h1>\n";
if ( parms.getProperty("offset") == null )
{
msg +=
/** This message is only to get the variable
The variable is sent via the <input>*/
"<form action='?' method='get'>\n" +
" <p>Enter Offset Amount: <input type='int' name='offset'></p>\n" +
"</form>\n";
}
else
{
/** Create Calendar variable */
Calendar now = Calendar.getInstance();
/** Create and cast offset variable */
int offset = Integer.parseInt(parms.getProperty("offset"));
/** Add the offset to the current date */
now.add(Calendar.DATE, offset);
/** Display updated date */
msg += "<p>New Calendar Date, " + now.toString() + "!</p>";
// "</form>\n" + add(Calendar.DATE,offset);
}
msg += "</body></html>\n";
return new NanoHTTPD.Response( HTTP_OK, MIME_HTML, msg );
}
public static void main( String[] args )
{
try
{
new HelloServer();
}
catch( IOException ioe )
{
System.err.println( "Couldn't start server:\n" + ioe );
System.exit( -1 );
}
System.out.println( "Listening on port 8080. Hit Enter to stop.\n" );
try { System.in.read(); } catch( Throwable t ) {};
}
}
Again, I'd really appreciate your help. I'm a little lost in the weeds here. PLEASE HELP!
