This should be simple,

How would one go about creating a small window in a processing project that displays the:

1. Serial.println("   ");

defined on a connected Arduino?

Basically I want to send a command from Processing, to an Arduino and have the above " Serial.println("   "); "  on the Arduino tell a Processing window that the command has been received. This works great with just the Arduino sending notifications back, and Processing is doing a fine job of delivering the commands to the Arduino; I just don't know where to begin on getting notifications back from the Arduino, through Processing.

Example:

Arduino:

1. Example:
   
   Arduino Code:
   
   void setup() {
     // initialize serial communication:
     Serial.begin(9600);
     // initialize the pins:
     for (int thisPin = 2; thisPin < 12; thisPin++) {
       pinMode(thisPin, OUTPUT
         );
     }
   }
   
   void loop() {
     // read the sensor:
     if (Serial.available() > 0) {
       int inByte = Serial.read();
      
       // Single quotes will tell the controller to get the ASCII value for the character.
       // Example 'a' = 97, 'b' = 98, and so forth:
   
       switch (inByte) {
   
         //Hello World Print Test:
   
       case 'q':
         Serial.println("Hello World");
         break;
        
         }
           }
             }

Processing: (Everything except the part that shows me the " Serial.println("Hello World"); " from the Arduino)

1. //Hello World Test (Minus the Print console)
    
   // load the serial library for Processing
   import processing.serial.*;
   // instance of the serial class
   Serial myport;
   
   // set the font
   PFont myFont;
    
   void setup()  {
     // screen size of the program
     size(250, 250);
    
     // List all the available serial ports in the output pane.
     println(Serial.list());
    
     // set the font to use
     myFont = createFont("verdana", 12);
     textFont(myFont);
   
     myport = new Serial(this, Serial.list()[0], 9600);
   }
     void draw()
   {
     background(0);
     noStroke();
     fill(150);
     // Text Label
     text("Hello World (q)", 5, 5, 200, 75);
   
     // start looking to see whats pressed and send a value
     // over the serial port
     if(keyPressed) {
   
   //Trigger Hello World Example from Arduino
    
   // q -Forward - 100%
       if (key == 'q') {
         myport.write('q');
       }
         }
           }
