Sending strings from processing to arduino - arduino

Question

I'm trying to set up communications between my PC, and my Arduino with the Processing environment, but the Arduino doesn't seem to be getting any of the messages I send. I doubled checked, and I know I can receive messages from the Arduino, but I can't send anything back. Does anyone know how to fix this?
Here's my test code for processing:
import processing.serial.*;
Serial myPort;
void setup(){
myPort = new Serial(this, Serial.list()[0], 9600);
}
void draw(){
myPort.write("test");
while (myPort.available() > 0) {
String inByte = myPort.readString();
println(inByte);
}
}
Here's my test code for the Arduino:
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
}
String data;
void loop() {
// put your main code here, to run repeatedly:
//Serial.println("is running");
if (Serial.available() > 0) {
// read the incoming byte:
data = Serial.readString();
// say what you got:
Serial.print("I received: ");
Serial.println(data);
}
}
I'd appreciate any help I can get! Thanks!

Okay, after looking into several different posts on the Arduino forum, I figured out what the problem is. The function processing uses to send data over serial does not automatically include a return character at the end of the string. This is important because the Arduino won't read from the serial buffer until it sees that return character. All I had to do was add "\r\n" to the end of each string I sent over serial, and that solved the problem!
