Functions

•  <text>charAt(<n>)  –  find<n>th character in <text>
• <text>.length  –  find the length of <text>
• split(<text to split>,<separator>)  –  split <text to split> with <separator>
• join(<list of texts>,<separator>)  –  join <list of texts> with <separator>
• <text to search>.indexOf(<character>)  –  find <character> from <text to search> It returns index of character, if it’s not found, it returns “-1”
• match(<text>, <header>+”{.*?}”+<footer>)  –  find sub texts between <header> and <footer> in <text>
• trim(<text>)  –  delete whitespace in <text>

Import

You can import txt file with following code:

String[] strings = loadStrings("textfile.txt");

Export

You can export txt file with following code:

saveStrings("textfile.txt", strings);
