Can someone help here as I've a requirement: How to count no. of words in a given email body? I am unable to achieve it!

Here is the apex and VF code: 
//Apex Code

 public class sendEmailbuttonApex
{
    public Account accounts            {set;get;}
    public String subject { get; set; }
    public String body { get; set; }
    public sendEmailbuttonApex(Apexpages.StandardController controller)
    {
        accounts=(Account)controller.getRecord();
    }
    public PageReference sendEmail()
    {
        List<Contact> conList=[Select Id, Email from contact where Email='abhishekk.twopirconsulting@gmail.com'];
        system.debug(conList);
        List<String> mail=new List<String>();
        for(Contact c:conList)
        {
            mail.add(c.Email);
        }
        Messaging.SingleEmailMessage msg1=new Messaging.SingleEmailMessage();
        msg1.setToAddresses(mail);
        msg1.setSubject(subject);
        msg1.setPlainTextBody(body);
        Messaging.Email[] emails=new Messaging.Email[]{msg1};
        Messaging.sendEmail(emails);
        PageReference p=new PageReference('/'+accounts.id);
        p.setRedirect(true);
        return p;

    }
}
  
//VF code

<apex:page docType="HTML-5.0" standardController="Account" extensions="sendEmailbuttonApex">
<apex:form>
      <script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
        <script>
        $(document).ready(function() {
            $("#word_count").on('keydown', function(e) {
            //j$('[id$=word_count]').on('keydown', function(e) {
        var words = $.trim(this.value).length ? this.value.match(/\S+/g).length : 0;
        if (words <= 200) {
            $('#display_count').text(words);
            $('#word_left').text(200-words)
        }else{
            if (e.which !== 8) e.preventDefault();
        }
    });
 }); 
       </script>
   
    
		<br /><br />
			<apex:outputLabel value="Subject" for="Subject"/>:<br />     
			<apex:inputText value="{!subject}" id="Subject" maxlength="80"/>
			<br /><br />
			<apex:outputLabel value="Body" for="word_count"/>:<br />     
             <apex:inputTextarea id="word_count" cols="30" rows="10" value="{!body}"/>
        <br />
