title: Find the certain word in the string
body: <p>I write program, which can recognize the certain word in the string, but i have a question. How to recognize a word in the string without gaps? (in one full string).</p>
  
  <pre><code>String string;
      String word;
  
      Scanner scan = new Scanner(System.in);
  
      string = scan.nextLine();
      word = scan.nextLine();
  
      if(string.matches(".*\\b" + word +"\\b.*")){
  
          System.out.println("found");
      }
  
      else {
  
          System.out.println("Error");
      }
