java sql like,如何在java中实现类似'LIKE'运算符的SQL？

I need a comparator in java which has the same semantics as the sql 'like' operator.

For example:

myComparator.like("digital","%ital%");

myComparator.like("digital","%gi?a%");

myComparator.like("digital","digi%");

should evaluate to true, and

myComparator.like("digital","%cam%");

myComparator.like("digital","tal%");

should evaluate to false. Any ideas how to implement such a comparator or does anyone know an implementation with the same semantics? Can this be done using a regular expression?

.* will match any characters in regular expressions

I think the java syntax would be

"digital".matches(".*ital.*");

And for the single character match just use a single dot.

"digital".matches(".*gi.a.*");

And to match an actual dot, escape it as slash dot
