Explanation:

a->b->         // Method with two String parameters and boolean return-type
  a.matches(   //  Check if the first input matches the regex:
   b           //   The second input,
    .replace("",".*"))
               //   where every character is surrounded with ".*"

For example:

a="HELLO WORLD"
b="LORD"

Will do the check:

"HELLO WORLD".matches("^.*L.*O.*R.*D.*$")

(The ^...$ will add the String#matches builtin implicitly, since it will always try to match the entire String.)
