cannot find a class or type named gregoriancalendar

i am trying to make a clock with arduino and processing…
my arduino code:

/* 
 * TimeSerial.pde
 * example code illustrating Time library set through serial port messages.
 *
 * Messages consist of the letter T followed by ten digit time (as seconds since Jan 1 1970)
 * you can send the text on the next line using Serial Monitor to set the clock to noon Jan 1 2010
 T1262347200  
 *
 * A Processing example sketch to automatically send the messages is inclided in the download
 */ 
 
#include <Time.h>  

#define TIME_MSG_LEN  11   // time sync to PC is HEADER followed by unix time_t as ten ascii digits
#define TIME_HEADER  'T'   // Header tag for serial time sync message
#define TIME_REQUEST  7    // ASCII bell character requests a time sync message 

void setup()  {
  Serial.begin(9600);
  setSyncProvider( requestSync);  //set function to call when sync required
  Serial.println("Waiting for sync message");
}

void loop(){    
  if(Serial.available() ) 
  {
    processSyncMessage();
  }
  if(timeStatus()!= timeNotSet)   
  {
    digitalWrite(13,timeStatus() == timeSet); // on if synced, off if needs refresh  
    digitalClockDisplay();  
  }
  delay(1000);
}

void digitalClockDisplay(){
  // digital clock display of the time
  Serial.print(hour());
  printDigits(minute());
  printDigits(second());
  Serial.print(" ");
  Serial.print(day());
  Serial.print(" ");
  Serial.print(month());
  Serial.print(" ");
  Serial.print(year()); 
  Serial.println(); 
}

void printDigits(int digits){
  // utility function for digital clock display: prints preceding colon and leading 0
  Serial.print(":");
  if(digits < 10)
    Serial.print('0');
  Serial.print(digits);
}

void processSyncMessage() {
  // if time sync available from serial port, update time and return true
  while(Serial.available() >=  TIME_MSG_LEN ){  // time message consists of a header and ten ascii digits
    char c = Serial.read() ; 
    Serial.print(c);  
    if( c == TIME_HEADER ) {       
      time_t pctime = 0;
      for(int i=0; i < TIME_MSG_LEN -1; i++){   
        c = Serial.read();          
        if( c >= '0' && c <= '9'){   
          pctime = (10 * pctime) + (c - '0') ; // convert digits to a number    
        }
      }   
      setTime(pctime);   // Sync Arduino clock to the time received on the serial port
    }  
  }
}

time_t requestSync()
{
  Serial.print(TIME_REQUEST,BYTE);  
  return 0; // the time will be sent later in response to serial mesg
}

my processing code:

/**
 * SyncArduinoClock. 
 *
 * portIndex must be set to the port connected to the Arduino
 * 
 * The current time is sent in response to request message from Arduino 
 * or by clicking the display window 
 *
 * The time message is 11 ASCII text characters; a header (the letter 'T')
 * followed by the ten digit system time (unix time)
 */

but when i click run button in processing i get this error “cannot find a class or type named gregoriancalendar”
Can you please help me solve this…

but when i click run button in processing i get this error "cannot find a class or type named gregoriancalendar" Can you please help me solve this..

Where do you expect this:

  GregorianCalendar cal = new GregorianCalendar();

to find the definition of the class?

Forgot to add import

import java.util.Date;
import java.util.Calendar;
import java.util.GregorianCalendar;
