How to find part of a word using a regular expression?

Question

Java

It is necessary to find a word or part of a word in the content using regex
There is a line: With this approach:String INPUT = "social network facebook";

Boolean result = INPUT.matches("\\w*face\\w*"); // false

the result will be false because it looks for the whole word (matches) .
Is it possible to compose a regular expression in such a way that (matches) looks for part of the word ?
We need an implementation without using the connection between the Pattern and Matcher classes in which there is matcher.find()(which works with this regular expression as I need it) if possible ...

Answer 1

.*word.*
