[ask] how to use an array of double in Java Processing

Processing Coding Questions
13

I got it to compile and run making 3 changes. Whether it does what you want is another matter! :smile:

Local variables must be initialised with a value before being accessed. So,

int resultClass;

should be

int resultClass = 0;

and

double  sf1, sf2, sf3, sf4, sf5, sf6;

should be

double  sf1 = 0, sf2 = 0, sf3 = 0, sf4 = 0, sf5 = 0, sf6 = 0;

And you need to replace main with setup() for Processing purposes. It doesn’t return anything.

void setup(){
  println("\nResult: ", calculate());
}
