calculating frequency of word lengths

I'm trying to create a little applet that loads a text file and then counts up and shows the frequency of word lengths in the file. So far I have this:
Code:
String words = "car three bear bee to a is";
String list[] = splitStrings(words);
int one = 0;
int two = 0;
int three = 0;
int four = 0;
int five = 0;
for(int i=0; i< list.length; i++) {
int word = list[i].length();
//println(list[i] + word);
if(word == 1) {
one++;
} else if (word == 2) {
two++;
} else if (word == 3) {
three++;
} else if (word == 4) {
four++;
} else if (word == 5) {
five++;
}
}
println("Single letter words:" + one);
println("Two letter words:" + two);
println("Three letter words:" + three);
println("Four letter words:" + four);
println("Five letter words:" + five);

Which even I know isn't very efficient, I've tried the loadStrings(); function but I can't seem to get it working.
I need advice on how to load a text file and how not to have to declare every possible word length as a variable. Anyhelp much appreciated.

In the reference section I read this code:
Code:
String lines[] = loadStrings("list.txt");
println("there are " + lines.length + " lines");
for (int i=0; i < lines.length; i++) {
println(lines[i]);
}

Thought, well, okay I'll have a go then.
Pasted it into Processing. Saved it as list.pde and then went to the sketchbook folder and into default. Opened up the "list" folder. Opened up the "data" folder. Created a new text file with the ole right click new txt file please. Wrote some gibberish and pressed return a few times. Saved the file.
Ran the Processing code.
First time I've used the command and it worked.
The only trouble I can see you having after that is it creates a new array division each time it detects a new line in the txt file. Can't be that hard.
Hope this is a little help.

Whoops, didn't notice that it did it line by line. Thanks

A little less long winded than your first code would be:
Code:
String words = "car three bear bee to a is";
String list[] = splitStrings(words);
int [] count = new int[5];
for (int i = 0; i<count.length; i++){
count[i] = 0;
}
for(int i = 0; i< list.length; i++) {
int word = list[i].length();
count[word-1]++;
}
for (int i = 0; i<count.length; i++){
println((i+1)+" letter words:"+count[i]);
}

Any multiple turn into an array. Any pattern run through a for loop. Keep (insert home town) tidy.

Fantastic, I've been trying to do somthing like that. Just trying to get my head around loops. Thanks!
Edit:
Just tried your code, only problem is that if I use if say a piece of text with 200 words in it, it would output "200 letter words: 0" etc. I'm trying to work out how to fix it, but if you've got any ideas...

Oh wait, I've got it sorted in a slightly dodgey way:
(see comment)
Code:
String lines[] = loadStrings("independent.txt");
String words = join(lines, " ");
String list[] = splitStrings(words);
//every things ok as long as source text is not less than 20 (see below)
int [] count = new int[20];
for (int i = 0; i<count.length; i++){
count[i] = 0;
}
for(int i = 0; i< list.length; i++) {
int word = list[i].length();
count[word]++;
}
for (int i = 0; i<count.length; i++){
println((i+1)+" letter words:"+count[i]);
}
