I'm new to processing and I'd like to make a constructor and later an array made of constructors. I did check the help and I've found quite a number of examples of constructors, but when I apply the same code to my sketch it doesn't work. Please help!

this is the code in my sketch, atm at least.

PFont fontA;
fontA = loadFont("CordiaUPC-48.vlw");
textFont(fontA);

String[] lines;
weatherData table[] = new weatherData[548];

int numLines = 0;
lines = loadStrings("Greenwich.txt");
numLines = lines.length;

size(500,500);
String txt=String.valueOf(numLines);

String s;
String s1;
String s2;
String s3;
String s4;
String s5;
String s6;
String s7;


//for(int i = 20; i<569; i++)
//{
s1 = trim(lines[20].substring(3,7));
s2 = trim(lines[20].substring(9,11));
s3 = trim(lines[20].substring(14,18));
s4 = trim(lines[20].substring(22,26));
s5 = trim(lines[20].substring(32,34));
s6 = trim(lines[20].substring(37,42));
s7 = trim(lines[20].substring(45,50));

if(s6.equals("---"))
{
 s6 = "0";
}

if(s4.charAt(0) == '-')
{
 s = s4.substring(1);
}



//}

text(s1, 0, 30);

class weatherData
{
 int yearw;
 int monthw;
 float tmax;
 float tmin;
 int af;
 int rainmm;
 float sunHours;

 weatherData(int y, int m, float tx, float tn, int a, int r, float s)
 {
   yearw = y;
   monthw = m;
   tmax =tx;
   tmin =tn;
   af = a;
   rainmm = r;
   sunHours = s;
 }
}

Don't mind the other part of the code, just the constructor part and the array made of constructors.

Anyway, I get the error message:
Semantic Error: Type "weatherData" was not found.

Please help!

Tnx for help, gonna try that now.
