Hi,
Hope this helps for you.
declare
a varchar2(1000):='ABBCCCDDDDEEEEE';
b number;
c varchar2(100);
d varchar2(100);
l number:=1;
k number:=1;
count1 NUMBER:=0;
begin
select length(a) into b from dual;
for z in 1..b loop
dbms_output.put_line('--------------------------------');
c:= substr(a,l,1);
if c IS NOT NUll then
     count1 := 0;
k :=1;
     for j in 1..b loop
     d:= substr(a,k,1);
     if d IS NOT NULL THEN
if(c=d) then
count1 := count1+1;
End if;
ELSE
k :=0;
     END IF;
     k :=k+1;
     end loop;
ELSE
l :=0;
END IF;
l := l+1;
dbms_output.put_line('Character : '||c||' count : '||count1);
dbms_output.put_line('--------------------------------');
end loop;
end;
