The code should be:

Validator numericValidator = new Validator((String s) -> s.matches("\\d+"));
boolean b1 = numericValidator.execute("aaa");
Validator lowerCaseValidator = new Validator((String s) -> s.matches("\\[a-z]+"));
boolean b2 = loweCaseValidator.execute("bbb");


Instead of:

Validator numericValidator = new Validator((String s) -> s.matches("\\[a-z]+"));
boolean b1 = numericValidator.validate("aaa");
Validator lowerCaseValidator = new Validator((String s) -> s.matches("\\d+"));
boolean b2 = loweCaseValidator.validate("bbb");
