deadlocks, rowlock and tablelocks

How can we simulate a deadlock, rowlock, tablelock?
What are the tables it will involve?
How do we debug and take care of the issue??
thanks,

table lock: lock table exclusive;
row lock: select for update ....;
deadlock : Have to be very bad developer.

Open 2 SQLPLUS sessions.
Table Lock :
Lock one in one session, and try to update the same table in another session.

Dead Lock:
Lock Table_A in one session

Lock Table_B in 2nd session.

Update Table_B in first session

Update Table_A is 2nd session.

Now look into alert.log file for the dead lock deduction.
