Counting Number Of Words From User Input

I tried the following code, OK:

Java Code:

String temp = "hi this sf hello is new what is this";
String[] cmd = temp.split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');

However, when i get the input from user , i didnt get the expected result:

Java Code:

System.out.println("Enter the input string to count the words: ");
String[] cmd = new Scanner(System.in).next().trim().split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');

Now Result for above code:

Enter the string to count the words:

hi this is new

words are: 1
