How to iterate a string in Ballerina?

Question

I am trying to get each character of a string and do some formatting and produce a new string in Ballerina. How can I iterate character-wise ?

I am on Ubuntu 16.04 and Ballerina 0.975.0

Any suggestions?

Answer 1

Based on the available string functions, I could come up with the following solutions.

Solution 1:

string s = "This is my string";
foreach c in s.split("") {
    io:println(c);    
}

Solution 2:

string s = "This is my string";
foreach i in 0..< lengthof s {
    io:println(s.substring(i, i+1));     
}
