Looping a StringList and count

How do I loop a stringlist and count the number of occurances of a letter in each string list item.
If the following is a string list:
0 aaaaaaaaaa
1 bbbbbbaabb
2 ccccaccccc

how do I get the count of a’s
like listitem[0]=10
listitem[1]=2
listitem[2]=1

thanks

Try a Java service for looping each string list and check for the character and increment the count if it is found for the list.

Use a FLOW loop step to iterate over the list. Create a Java service to count the number of times a particular character appears. Call that service from within the loop. You can put the results of each count in the output list of the loop.
