Hi All,
Thank you for your responses to my previous post...
I got another question to ask you guys!!! I need to sort a mutable
vector using the sortUsingMethod. The documentation said:
...
public void sortUsingMethod(java.lang.String comparator)
Sorts the receiver's elements in ascending order, as determined by the
comparison method named by comparator. The comparator message is sent to
each object in the vector, and has as its single argument another object
in the vector. The comparator method is used to compare two elements at
a time and should return -1 if the receiver is smaller than the
argument, 1 if the receiver is larger than the argument, and 0 if they
are equal.
...
Well, I passed in a string, let say "ascending" (sorry, I am a bit
clueless), the compiler, then complains "Incompatible type for method.
Can't conver java.lang.String to next.util.Selector". Huh??? I thought
the documentation asks me to pass in a string !??? Okay, fine! I will
pass in a next.util.Selector, but, there is no documentation for
next.util.Selector. If you have experience using this method, or know
where documentation for next.util.Selector is, please give my some
pointer!
many thanks!
