Declaration and Traversal of Arrays in Oracle Stored Procedures

-- declare array
TYPE V_ARRAY_TABLE IS TABLE OF VARCHAR2(300);
V_ARRAY V_ARRAY_TABLE := V_ARRAY_TABLE('aaa','bbb');

-- loop through the array
FOR i in 1..V_ARRAY.count LOOP
  DBMS_OUTPUT.PUT_LINE(V_ARRAY(i))
END LOOP;

Note: The array must be declared, the array in oracle is a table;
