This is by no means an exhaustive list, just what I happened to notice (mostly grammar and spelling errors).
redundant "a" in "... on a cyclic environments ..."
than -> then in "... and than ended up ..."
The C# code example is invalid, formal parameter pArray of method Change must be declared as "ref int".
eventually != eventuell
Inconsistent notation: is it "=>↑" or "=>!"?
First Snippet: redundant parenthesis at the end
"ShopingItem" -> either "ShopItem" or "ShoppingItem"
First paragraph, second bullet point: than -> then
Last bullet point: use -> are
The wrong line is marked with "run-time error":
An ArrayStoreException would be thrown further up when assigning "objects = new Integer(5);" since objects has run-time type String.
"In practise" -> "In practice"; practise is a verb
Finally, as others have noted, the inconsistent use of *LAE and *WAE is very annoying and could probably be fixed with a simple search&replace.
