Hi there, I am building a very simple sketch to visualize text and data.
It works when is like this(see below), but not when I use void setup and void draw (see second option after). does anyone know why? Thanks!
```auto
String filename= "test1.csv";
String [] sentence;
PFont f = createFont("Helvetica", 40);
size(500,500);
sentence=loadStrings(filename);
printArray(sentence);
textFont(f);
textSize(40);
text(sentence[1], 10, 100);
```

```auto
String filename= "test1.csv";
String [] sentence;
PFont f = createFont("Helvetica", 40);
void setup() {
size(500,500);
sentence=loadStrings(filename);
printArray(sentence);
}
void draw(){
textFont(f);
textSize(40);
text(sentence[1], 10, 100);
}
```

What happens falsely, does it start, does it throw an error?
Maybe move this
```auto
f = createFont(“Helvetica”, 40);
```
Into setup after size

as you use a .csv file i assume you would be better of using
[https://processing.org/reference/loadTable\_.html](https://processing.org/reference/loadTable_.html)
instead of
[https://processing.org/reference/loadStrings\_.html](https://processing.org/reference/loadStrings_.html)

anyhow
```auto
String filename= "test1.csv";
String [] sentence;
sentence=loadStrings(filename);
printArray(sentence);
```
works with the data file in
/data/test1.csv
same as
```auto
String filename= "test1.csv";
String [] sentence;
void setup() {
size(500,500);
sentence=loadStrings(filename);
printArray(sentence);
}
void draw(){}
```

Yes, the error it gives is:
java.lang.reflect.InvocationTargetException

So no createFont before setup, instead after size
Before setup
PFont f ;
In setup() (after size() command)
f = createFont(“Helvetica”, 40);

Yes, is the csv file located in your data folder?

I think a few things are set up in the size() command behind the scenes.
Hence some commands only work after size(), especially file related stuff and width and height…

Yes, while it isn’t strictly enforced, the Processing documentation actually says **must** :
> In a program that has the **setup()** function, the **size()** function **MUST** be the first line of code inside **setup()** , and the **setup()** function must appear in the code tab with the same name as your sketch folder.

I know Processing since v1.5.1. Even back then, that wasn’t a MUST. 😆
