else statement with no if condition isn't default [duplicate]

This question already has an answer here:

• Missing return statement for if/else statement 8 answers

public int compareTo(Tool b)
{
    if(cost > b.cost)
        return 1;
    else if(cost == b.cost)
    {
        if(name.compareTo(b.name) < 0)
            return 1;
        else if(name.compareTo(b.name) == 0)
            return 0;
        else if(name.compareTo(b.name) > 0)
            return -1;
    }
    else
        return -1;
}

NetBeans gives an error at the last brace because "missing return statement". This is solved if I remove the "else", but shouldn't return -1 be the default codepath?
