Arduino shows processing by a string of oral values

Arduino Port Code:

int red=255; Create variables to store the data to be sent
int green = 2;
int blue = 3;
void Setup ()
{
  serial.begin (9600);//define a data transfer rate of 9600 bits
}
void Loop ()
{ 
  serial.print (red);
  Serial.print (",");
  Serial.print (green);
  Serial.print (",");
  Serial.print (blue);
  Serial.print ("\ n");
  Delay (+);
}

Above red, Green,blue is replaced with the value obtained by the color sensor in the actual application. Processing-Side code:

Import processing.serial.*;//introduces serial library

int r = 0;
int g = 0;
int b = 0;

Serial myport;//Create a Serial object named "MyPort"
Void Setup () {
  myport = new Serial (This, "COM7", 9600);
  Myport.bufferuntil (' \ n ');  Buffer until meet ' \ n ', then call the event listener
  //define MyPort port and data transfer rate
  //should be consistent with Arduino
}
void Draw () {
  background (204);
  Fill (R, G, b);
  Rect (+,-);
}
Listen to the event. When the buffer filled, run this method

void Serialevent (Serial p) {
  String instring = p.readstring ();
  Print (instring);
  
  string[] List = Split (instring, ', ');
List[0] is now "Chernenko", List[1] is "Andropov"
  ... r = Int (list[0]);
  g = Int (list[1]);
  b = Int (list[2]);
}
