For the remaining non-ASCII characters, either the actual Unicode character (e.g. ∞) or the equivalent Unicode escape (e.g. \u221e) is used. The choice depends only on which makes the code easier to read and understand, although Unicode escapes outside string literals and comments are s...

split public String[] split(CharSequence input) 将给定的输入序列分成这个模式的匹配。 该方法的工作原理是通过调用具有给定输入序列和限制参数为零的双参数split方法。 因此,尾随的空字符串不会包含在结果数组中。 输入"boo:and:foo" ,例如,使用以下表达式得到以下结果: Regex Result : { "boo", "and", ...
