you can create a script using this sql
SELECT
'drop ' || object_type || ' ' || object_name || decode(object_type,
'TABLE',
' CASCADE CONSTRAINTS') || ';'
FROM
dba_objects
WHERE
object_type = 'TABLE' and
owner = 'USERNAME'

You need to spool to a sql file, then start that file, so that the commands that you see are run and the tables are dropped:
STORE SET saved_settings REPLACE
SET ECHO OFF FEEDBACK OFF HEADING OFF PAGESIZE 0 SERVEROUTPUT ON VERIFY OFF WRAP ON
SPOOL drop_tables.sql
SELECT 'DROP ' || object_type || ' ' || object_name
|| DECODE (object_type, 'TABLE', ' CASCADE CONSTRAINTS' || ';'
FROM dba_objects WHERE object_type = 'TABLE' AND owner = 'rehman';
SPOOL OFF
START saved_settings.sql
START drop_tables.sql
