I'm getting a compiler error for this line:
Collections.sort(terms, new QuerySorter_TFmaxIDF(myInteger));
My customized Comparator is pretty basic; here's the signature and constructor:
public class QuerySorter_TFmaxIDF implements Comparator<Term>{
private int numberOfDocs;
QuerySorter_TFmaxIDF(int n){
super();
numberOfDocs = n;
}
}
Is there an error because I'm passing an argument into the Comparator? I need to pass an argument...
There's no reason you can't pass an argument to that constructor. Your code is missing:
The superclass. Your constructor calls super() so I assume there is one; and
The compare() method required by the Comparator interface.
What exactly is numberOfDocs meant to do here?
Your Comparator needs to compare Strings because your ArrayList contains Strings.
public class QuerySorter_TFmaxIDF implements Comparator<Term> {
has to be
public class QuerySorter_TFmaxIDF implements Comparator<String> {
The problem lies with your comparator. It's for sorting Term-s but the array you're handing it via the Collections.sort() method has elements of type String.
terms?
