Jdbc-statement execute method

Question

in java documentation
it is given
............., a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string.
The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).
what is that procedure that return multiple result sets
please some body clarify or place where i can get more details

Answer 1

See if out parameters are used i can call CallableStatement's getter methods to retrieve value
after execution .
but the api is telling writing a dynamic procedure execution where procedure returns more than
ResultSet(DQL) or updateCount(DML) . iam lokking for a procedure in oracle where this is possible
