Enhanced for-loop

Can you please convert this enhanced for loop to an ordinary one?
for (String sentence : notes.split(" *\."))

I'm fond of enhanced and normal for loop when the data type is an integer. But if it is a string, I'm confused. Thank you very much!

split returns you the String[].

String[] array=notes.split(" *\.");
for(int i=0;i<array.length();i++) {

    System.out.println(array[i]);
}

String[] sentences = notes.split(" *\.");
String sentence = null ;
int sentencesLength = sentences.length;

for(int i=0;i<sentencesLength;i++){
sentence = sentences[i];
//perform your task here

}

Eclipse Juno has in-build feature for converting for-each to index based loop. Check it out.

You should take a look at For-Each's Doc. 

String[] splitted_notes = notes.split(" *\. ");
for (int i=0; i < splitted_notes.length; i++) {
  // Code Here with splitted_notes[i]
}

Or a loop more similar to for (String sentence : notes.split(" *\."))

ArrayList<String> splitted_notes = new ArrayList<>(Arrays.asList(notes.split(";")));
for(Iterator<String> i = splitted_notes.iterator(); i.hasNext(); ) {
  String sentence = i.next();
  // Code Here with sentence
}

I guess the regex itself is a wrong one. The compiler will say

illegal escape character

if

"*\."

is the regex. So I am assuming that you are trying to split a string by have having

. (a dot)

as a delimiter. In that case, the code would be like

String[] splittedNotes = notes.split("[.]");
for (int index = 0; index < splittedNotes.length; index++) {
   String sentence = splittedNotes[index];
}

On a polite note, you could have tried and got this by yourself. Cheers.

Ordinary for loop - 

String[] strArray = notes.split(" *\.");
String sentence = null;
  for(int i=0 ;i <strArray.length ; i++){
    sentence = strArray[i];
   }

String [] array = notes.split(" *\."));
String sentence;
for(int i = 0; i < array.length; i ++) {
sentence = array[i];
}

You could have something like so:

String[] splitString = notes.split(" *\."));
for (int i = 0; i < splitString.length; i++)
{
    //...
}

OR

for(String str : splitString)
{
    //...
}
