[Technical question]

Question

I need an algorithm to count the number of words in string regardless of spaces between them.
example:
String s="this is an example";

*note: I tried an algorithm and it worked, but only in some cases, and now trying to get some more ideas.

Answer 2

Here is an option:
Read every char in the string
define a wordReading mode
enter wordReading mode on first char that is not a space.
exit wordReading mode on first space
store the word found and increase the number of found words upon exiting wordReading mode.
use the number of found words to create an array and store extracted substrings.

I'd go for the suggested regex solution.

Answer 3

i would look into regular expressions.
You could do something like split the string into an array
I believe its
String[] array = s.split ("\\s+");
and then just do array.length for the number of words

Answer 4

@Edward thanks, but I'm looking for a manual way to do that 😃
Besides, this will take only the first space,
nothing different than split on single space.

Answer 5

@seamiki thanks for your efforts, this is the same approach I used, except of storing in the array .
although I know it can be solved using regex, but I needed to do it manually using loops ..

Answer 6

there is your code . ping me whenever you copy the code so I can. delete it.
