例如，下列的代码声明了一个Comparator，该表达式对字符串的长度进行比较，并使用一个lambda表达式来定义Comparator：。

For example, the following code declares a Comparator that compares strings by length and USES a lambda expression to define the Comparator:.

目标字符串很小时，这种方法只比正则表达式快一点，但更重要的是，字符串的长度不再影响执行测试所需要的时间。

This is just a bit faster than the regex-based test with small target strings, but, more importantly, the string's length no longer affects the time needed to perform the test.
