Conditional Table Creation

In Transact SQL, I can conditionally create tables using the following script:

if object_id('footable') is null

        create table footable ( a int, b int null ) else

        alter table footable add b int null go

Is there any way in Oracle to use conditional statements to perform different actions under different circumstances?
