Answer 1

Sorry, just saw this. Here you go. It's a start. Basically, just storing the string array into a list for more functionality, and then I create a new list that we'll place all the "valid" words into. Each time we add an element to the new list, I increase wordcount so we get a proper count of the words. Hope this helps.

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String input = sc.nextLine();
String[] words = input.split(" ");
List<String> wordsList = new ArrayList<String>(Arrays.asList(words));
List<String> wordsFinal = new ArrayList<String>();
int wordCount = 0;

for (String s: wordsList)
{
if(s != null && !s.isEmpty())
{
wordsFinal.add(s);
wordCount++;
}

}

if (input.length() != 0){
System.out.println("Your original sentence was:\n" + input + "\n");
System.out.println("Your sentence has got " + wordCount + (" word(s)."));
}else{
System.out.println("Please enter a sentence to check...\nGood luck!");
}
}

Thanks mate!
How can I do this? Any examples?

Answer 3

Check for double spaces. ;) If not, it'll count each additional space as a word. There may be an easier way, but you can just have it find the consecutive spaces and replace it with one space instead.
