forgot to log-in, and I made a typo.

* but this did not work if I typed "peter griffin is (five spaces) irish", since there are multiple number of spaces dividing the word.

meaning there are five spaces between "is" and "irish"

Just use the String split() method, with " " as the param. It will return a String[] with one word per element.

If you don't want to use String methods, you can always loop as you said, and "create" the words.
here is a pseudo code:
have a String currentWord variable.

1. loop the sentence
 1.1 if the next char is not space, add it to currentWord.
 1.2 else (the char is space) 
   1.2.1 if the currentWord is NOT empty, 
      1.2.1.1 add it to the words array
      1.2.1.2 empty currentWord (currentWord = "")
2. print the words array

you will have to use an ArrayList of String Object as the words array in that case (and not a 'plain' Array) since you don't know how many String objects (words) you might have.

String[] strArray = str.split(" ");

I guess that's the best way to go, but is there a manual way of doing the same thing without using split()?

You can always
char[] digit = str.toCharArray();
for() loop into digit[] to count the ' '
make a String[] array of count of ' ' + 1
repeat your loop and fill a StringBuilder
when you encounter a ' ' or end of the array convert the StringBuilder into a String and reset it to ""

I understand your method and I tried it, and I successfully divided one space between two spaces, but failed if there were more than one space in between...I think I made a mistake somewhere but I guess I'll just use split(). thank you!
