Answer 1

Also if Table statistics have been gathered(analyze table or DBMS_STATS) then this can also be used:
SQL> create table TEST_ABC
  2  (name_ABC varchar2(200));
Table created.
SQL> insert into TEST_ABC
  2  values('ABC');
1 row created.
SQL> insert into TEST_ABC
  2  values('DEF');
1 row created.
SQL> commit;
Commit complete.
SQL> select table_name, num_rows from all_tables where table_name = 'TEST_ABC';
TABLE_NAME                       NUM_ROWS
TEST_ABC
SQL> analyze table TEST_ABC compute statistics;
Table analyzed.
SQL> select table_name, num_rows from all_tables where table_name = 'TEST_ABC';
TABLE_NAME                       NUM_ROWS
TEST_ABC                                2
