Implement a regular expression as a Java String p like so String p- such that s a regular expression pattern that will match any String that represents UPI. Your answer must include the whole line of code above, meaning that the*must be properly backslash-escaped both in terms of backslash escapes required for regular expressions and any backslash escapes required to put the expression inside the quotes above Your answer will be inserted automatically into a test method matchO like so public void match(String s) String p System.out.printin (Ss.matches(p)? "match" + S: "does not match " + S); the test cases will invoke this method. Example The following are valid UPIs whsuo14 csee015 kng001 The following are invalid UPIs . abcd1234 . ab12 For example Test Result match("whsue14") match whsu match("a123"); does not match a123 Answer (penalty regime: 0 %) 1 lpublic void match(String s) [ 4 5 System.out.println(s.matches (p)? "match "+S: "does not match " S); 7
