String functions

Loaded data, from a file or a spreadsheet can be in numbers, or in text.
When working with text you have to know about the functions which can manipulate text.
Say we have the text

String hString = `Hello world and especially during carnaval`


And we want to have the seperated words in a list

String hString = "tester and rester";
String[] StringElements = split(hString, " ");
for (int i =0; i< StringElements.length ;i++) println( StringElements[i] );

we have the function split this gives an array which as elements the words if you use the space as a delimiter.

String hString = "tester";
println( hString.length());


To find a specific word the function indexOf is used

String hString = "tester";
println( hString.indexOf("ster"));


This can be useful extraction words from a twitterstream and doing something with these special words.
