What SQL statements Does oracle use to determine whether the table does not exist?

The ORACLE tutorial is: what SQL statements are used in oracle to determine whether the table does not exist. SQL server is used to determine whether statements in tables or views are unavailable in ORACLE. How can I write them.
Thank you. Questioner:-best answer exists (select tname from tab where tname = 'tablename ')

Remember that the table name should be in uppercase, because ORACLE is case sensitive and all table names are stored in the tab table.
