I want to check if my String contains words with a specific length

String s = "ab a abc ac";
if(s.contains(/*any words with 3 or more letters which would be 'abc'*/){
   //doSomething
}

Is there a way to do this in regex or with a simple method? Similar to

s.contains("[a-za-za-z]"); //or
s.contains().lettersInARow(3);

What I want is to find these and throw an Error when something longer than 2 characters is found
