NVARCHAR and NCHAR in oracle Oracle supports multiple charactersets at the same time through its use of the NLS* paramters. select * from nls_database_parameters where parameter in ('NLS_LENGTH_SEMANTICS', 'NLS_CHARACTERSET', 'NLS_NCHAR_CHARACTERSET'); There are two things to note The value of NLS_CHARACTERSET The value of NLS_NCHAR_CHARACTERSET on my system the values are the following NLS_NCHAR_CHARACTERSET = AL16UTF16 NLS_CHARACTERSET = WE8ISO8859P1 If you haven’t already guessed from the title of this article, NVARCHAR and NCHAR are two additional data types which behave similar to VARCHAR and CHAR....

Initializing Lists Why is this List<Integer> a = new List<Integer>({1,2,3}) not possible? Simple workaround class ListInit { public static void main(String args[]){ List<Integer> a = Arrays.asList(1,2,3); } } but, Is it not possible to initialize a List with an array literal? It is! That means Arrays.asList() should work with an array literal. But the below doesn’t work. List<Integer> a = Arrays.asList({1,2,3}); Although this does with the ’new’ keyword. List<Integer> a = Arrays....
