Sending two arrays to Arduino from Processing - arduino

Question

I'm trying to pass multiple variables (n number of strings and n number of ints) from processing to my Arduino. I found this tutorial online and managed to send a single value. Now I have two arrays that both need to be accessed by the Arduino filesTypes[] and filesSizes[]. filesTypes[] consists of a 3 char long strings while fileSizes[] is an array of different integers.
Here is my Processing code:
import processing.serial.*;
Serial myPort; // Create object from Serial class
String[] fileTypes;
int[] fileSizes;
String[][] lines;
void setup()
{
size(200,200); //make our canvas 200 x 200 pixels big
String portName = Serial.list()[1]; //change the 0 to a 1 or 2 etc. to
match your port
myPort = new Serial(this, portName, 9600);
launch( sketchPath("") + "/test.bat");
}
void draw() {
if (mousePressed == true)
{ //if we clicked in the window
txtToStrg();
myPort.write('1'); //send a 1
txtToStrg();
} else
{ //otherwise
myPort.write('0'); //send a 0
}
}
void txtToStrg(){
String[] lines = loadStrings("list.txt");
fileTypes = new String[lines.length];
fileSizes = new int[lines.length];
for (int i = 0 ; i < lines.length; i++) {
if(lines[i] != null) {
String[] splitLine = split(lines[i], ' ');
fileTypes[i] = splitLine[0];
fileSizes[i] = int(splitLine[1]);
println(fileTypes[i] + " = " + fileSizes[i]);
}
}
}
And here my Arduino code:
char val; // Data received from the serial port
int ledPin = 4 ; // Set the pin to digital I/O 13
void setup() {
pinMode(ledPin, OUTPUT); // Set pin as OUTPUT
Serial.begin(9600); // Start serial communication at 9600 bps
}
void loop() {
if (Serial.available())
{ // If data is available to read,
val = Serial.read(); // read it and store it in val
}
if (val == '1')
{ // If 1 was received
digitalWrite(ledPin, HIGH); // turn the LED on
} else {
digitalWrite(ledPin, LOW); // otherwise turn it off
Serial.print(val);
}
delay(10); // Wait 10 milliseconds for next reading
}
If a pass anything but a char it stops working.
