Generics problem in java

[Gillian Anderson]

Hello
I have a problem with my code, please check if this is correct and see if you can explain me this.
Here is the code:

<person> Comparator com = ascending? 
New compersonne()Collectibles.reveseOrder(New compersonne());

If you can explain me how this code works then you please explain me.

Hello,
See the following

 condition? Value_if_true: Value_if_false

So in your case whether ascending is true then c will New ComparePersonne() Otherwise it will Collections.reveseOrder (new ComparePersonne ()).
With if traditional one would write this:
Here is the code

	Comparator <person> c;
	if (ascending) {
		c = New ComparePersonne();
	} else {
		c = Collections.reveseOrder(New ComparePersonne());
	}

Hello,
You're in the presence of a conditional operator.
Here is a small example

max = (a> b) ? a: b

is equivalent to the statement

if (a> b)
    max = a;
else
    max = b;

This small, simple example will help you understand what's happening at home.

Hello,
It is a simplified syntax of "if then else" for simple cases:
Here is the code for the same

condition? instruction if it is true: if statement

If you do have any more problem regarding this then you can post back here. But before this try this in your code and if you have any more problems then do post back.

Hello,
See, if this can help you

List<String>[] lst = new List<String>[10]; // illegal
Object[] obj = lst;  // OK because List<String> is a subtype of Object
List<Integer> li = new ArrayList<Integer>();
li.add(new Integer(3));
obj[0] = li; 
String str = lst[0].get(0);
