FIND Option in a TextArea ?

Question

How can I implement a find Option in a Text Area ?
I want to enter a string and have it found throughout
the text.
I believe there must be ready code for sth common like
that.

Answer 1

Some code to get started.
   public void findWord(TextArea ta,String word) {
      String text=ta.getText();
      int start=text.indexOf(word);
      if(start==-1) { //-1 means not found
         ta.setCaretPosition(text.length()-1);
      } else {
         int end=text.indexOf(" ",start);
         if(end==-1) end=text.length(); // for last word in string
         ta.select(start,end);
