Can't sort in Java 1.5 with generics

I've been getting odd compile errors when trying to sort while using

I have the following code:

static final List<Class> levelList;
static {
Vector<Class> v = new Vector<Class>() ;

v.add(myClass1. class);
v.add(myClass2. class);
v.add(myClass3. class);

Collections.sor t(v);
levelList = Collections.unm odifiableList(v );

which causes the compile error:

C:\dev\cvs.kitf ox.com\scarlet\ src\com\kitfox\ scarlet\levels\ ScarletLevelLis t.java:34:
cannot find symbol
symbol : method sort(java.util. List<java.lang. Class>)
location: class java.util.Colle ctions
Collections.sor t((List<Class>) v);
However, if I change the sort command to

Collections.sor t((List)v);

Things work. Is there a way to write the above code so that it
compiles correctly with generics?

Here is the "lead C# architect" attempting to impugn C++ templates (bottom of the page). http://www.artima.com/intv/generics2.html (bottom of the page) (Full article begins at http://www.artima.com/intv/generics.html) I think every employee at Micrsoft must be required to take a class in "FUD marketing" before speaking with anyone outside the company.

Java programmers seem to always be whining about how confusing and overly complex C++ appears to them. I would like to introduce an explanation for this. Is it possible that Java programmers simply aren't smart enough to understand C++? This is not merely a whimsical hypothesis. Given my experience with Java programmers --- the code they write and the conversations they have --- Occam's Razor points to this explanation. For example,...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

For most users, this new feature is actually very convenient. If you want to control the update process,...
