    You can use Regular Expression to find all the phone numbers in your input paragraph and then replace them with surrounding anchor tags like <a href="tel: <phonenumber>"><phonenumber></a>

    Your code should be somewhat like this:

    Output

    INPUT PARAGRAPH                                                                                                                                                                 
    -----------                                                                                                                                                                     
    <p>Lets say that this is a sample paragraph with one phone number like 800-965-2321 
    and another phone number let's say 70923-23124</p>                                          
    -----------                                                                                                                                                                     
    
    OUTPUT PARAGRAPH                                                                                                                                                                
    -----------                                                                                                                                                                     
    <p>Lets say that this is a sample paragraph with one phone number like <a href="tel: 800-965-2321">800-965-2321</a>    
    and another phone number let's say <a href="te: 70923-23124">70923-23124</a></p>                                                                                                                                                       
    -----------         
    

    Java Code

    import java.util.regex.Matcher;
    import java.util.regex.Pattern;
    
    // our main class becomes a file but the main method is still found
    public class HelloWorld
    {
      public static void main(String[] args)
      {
        String htmlParagraph = "<p>Lets say that this is a sample paragraph with one phone number like 800-965-2321 and another phone number let's say 70923-23124</p>";
        System.out.println("INPUT PARAGRAPH
    -----------
    "+htmlParagraph+"
    -----------
    ");
        Pattern p = Pattern.compile("([\\d -]{8,13})");
        Matcher m = p.matcher(htmlParagraph); 
        htmlParagraph = m.replaceAll(" <a href=\"tel:$1\">$1</a> ");
        System.out.println("OUTPUT PARAGRAPH
    -----------
    "+htmlParagraph+"
    -----------
    ");
      }
    }
