Oracle 9 table names are not case sensitive

Question

Sorry about the trivial question, but I noticed that when I am creating table in Oracle their names is always upper case.
Example:
CREATE TABLE MyTable (i NUMBER(5))
CREATE TABLE MYTable (i NUMBER(5))
CREATE TABLE MyTABLE (i NUMBER(5))
CREATE TABLE MyTablE (i NUMBER(5))
it is the same table. Is it true that Oracle cannot create tables with names case sensitive, or I am doing something wrong.
Any help

Answer 1

You can create case sensitive table with table names enclosed in quotes.
SQL> create table sample(id number);
Table created.
SQL> select table_name from user_tables where upper(table_name)='SAMPLE';
TABLE_NAME
SAMPLE
SQL> create table "sample"(id number);
Table created.
SQL> select table_name from user_tables where upper(table_name)='SAMPLE';
TABLE_NAME
SAMPLE
