Answer 1

Then use TABLE and not VARRAY.
SQL> DECLARE
  2     TYPE type1 IS TABLE OF VARCHAR2(10);
  3     v_tab type1;
  4  BEGIN
  5     v_tab:=type1('SANKAR','BALAJI','SANA','PADMA');
  6
  7     dbms_output.put_line('No of Elements in the Lists are :' || V_TAB.COUNT);
  8
  9     FOR I IN v_tab.first..v_tab.last
10     LOOP
11             BEGIN
12                     IF I = 2 THEN
13                             v_tab.delete(I);
14                     END IF;
15                     dbms_output.put_line(V_TAB(I));
16             EXCEPTION
17                     WHEN NO_DATA_FOUND THEN
18                             NULL;
19             END;
20     END LOOP;
21  END;
22  /
No of Elements in the Lists are :4
SANKAR
SANA
