String[] count_words= sentences.split(" "); is splitting the input argument by " " that means that length of this array is the number of words. simply print the length out.

public static void main(String[] args) {
    Scanner sca = new Scanner(System.in);
    System.out.println("Please type some words, then press enter: ");
    String sentences= sca.nextLine();
    String[] count_words= sentences.split(" ");
    System.out.println("number of word is "+ count_words.length);
}

example:

oliverkoo@olivers-MacBook-Pro ~/Desktop/untitled folder $ java Main
Please type some words, then press enter: 
my name is oliver
number of word is 4

The method call count.length() is returning the length of each word because the loop is assigning each word to variable count. (This variable name is very confusing.)

If you want the number of words in the sentence, you need the size of the count_words array, which is count_words.length.
