If i had an array called List and was able to iterate through it, pulling out each element like this:

for(i = 0 ; i< List.size()-4 ; i++){
 
 System.out.println(seqList.get(i));
}

Is there any way to use this piece of code provided by titaniumdecoy:

double x = map.get('A')[0];

but like this:

double x = map.get(seqList.get(i))[0];

So i don't have to check what value 'i' is before i assign it a value from the map?

^^^Thats giving me errors.

If you want to iterate through the set of double values assigned to a particular letter in the map, you can do the following:

for (double i : map.get('A')) {
      System.out.println(i);
}

If instead you want to iterate through the first double value assigned to each letter value in the map:

for (char i : map.keySet()) {
      System.out.println(map.get(i)[0]);
}

I worked something out. Incedently, does anyone know how to auto-indent an entire piece of code in Netbeans? Im using version 5.0.
