Partially match strings in case of List.contains(String)

Question

I have a List

List list = new ArrayList();
list.add(\"ABCD\");
list.add(\"EFGH\");
list.add(\"IJ KL\")         


        

Answer 1

As a second answer, upon rereading your question, you could also inherit from the interface List, specialize it for Strings only, and override the contains() method.

public class PartialStringList extends ArrayList
{
    public boolean contains(Object o)
    {
        if(!(o instanceof String))
        {
            return false;
        }
        String s = (String)o;
        Iterator iter = iterator();
        while(iter.hasNext())
        {
            String iStr = iter.next();
            if (iStr.contain(s))
            {
                return true;
            }
        }
        return false;
    }
}

Judging by your earlier comments, this is maybe not the speed you're looking for, but is this more similar to what you were asking for?
