Answer 1

Use the String.contains method.

String str = "777 unspecifieduser 330";
if (str.contains("unspecified")) {
    // ...
}

A slighly more general approach would be to do use regular expressions:

"777 unspecifieduser 330".matches(".*unspecified.*")

If you’re interested in where the substring occurs. Use the String.indexOf method.
