matching a word with other text

I am making a program which takes users data to sign them up for an account. For one of the parts, I want to make an error message for whenever their password they choose has a word in it similar to their username. example: username = John. password = 5john123. Error! your password cannot include the username. I was looking through past questions and I found an answer that helped me. but only to a point. The code someone suggested only made it so that if the password and username are exactly the same, then it would display an error message. This is what they suggested: 

if (Arrays.asList(password.split("[\\s]")).indexOf(name) != -1)  
              System.out.println("Error!  Your password cannot include your username");   
              else            
              System.out.println("valid password");

This above code only works if the password and username are the same. if anything is added to either side it doesn't work.

How do I modify this so that no matter if there are numbers added on either side, it still finds whether or not the username is included in the password? Thank you.

You could do something like:

String userName = "John";
String password = "5john123";
if (password.toLowerCase().contains(userName.toLowerCase())) {
    System.out.println("Error! Your password cannot include your username");
} else {
    System.out.println("valid password");
}
