 Currently the API

Requirement 1 : Use regular expressions and verify whether or not my custom to meet the requirements to be matched string

Method customMatcher (String testStr) match the custom regular

If you use a custom regular expression matching string matching, there is need to construct a reference to the incoming object of regular expressions to create RegexUtil, by calling the object matching string customMatcher (String testStr) passed to be matched , for the prevention of air pointer exception, this class does not provide the constructor with no arguments

System.out.println(new RegexUtil("[0-9]{3}").customMatcher("213"));

 The result is true

Requirement 2 : Use Expression tools provide the matching string

genericMatcher (String regexExpre, String testStr) generic regular matcher

Only through . RegexUtil GenericMatcher (regexExpre String, String TestStr) can be realized string matching, the first parameter is a predefined constant, and the second expression is a string to be matched, such as

boolean reslut = RegexUtil.matcher(RegexConstant.E_MAIL, "[email protected]");
System.out.println(reslut);

 The result is true

 Follow-up needs to be improved in ....
