Help with formal parameter, ArrayList

[ezkatz19]

I need to pass an ArrayList named Pairs through my method Encode.
When I run try to compile the code without filling in the parameters, leaving it Encode(), it obviously gives me an error message, which reads:
Encode(java.util.ArrayList) in [myprogram'sname] cannot be applied to ()

How do I format Pairs so that it will correctly compile? I don't understand what it means by java.util.ArrayList; if I were, say, to need to put in a String, it would just read Encode(String), and I wouldn't have to write the variable type, just the name, but this won't work if I try Encode(Pairs)

Please show us your code and some context. Have you used ArrayLists at all yet? Also, please re-name your methods and variables so that they all begin with lower case letters. Only classes, interfaces and the like should begin with capital letters.

Never mind, I got it. And thanks for the tidbit about the capital letters
