Pattern.CASE_INSENSITIVE); 有关正则表达式的话题是非常丰富,而且复杂的,用Java来实现也非常广泛,则需要对regex包进行的彻底研究,我们在这里所讲的只是冰山一角。即使你对正则表达式比较陌生,使用regex包后会很快发现它强大功能和可伸缩性。如果你是个来自Perl或其他语言王国的老练的正则表达式的黑客,使用过regex包后,...
同样地,我们可以使用Pattern.CASE_INSENSITIVE标志来进行不区分大小写的替换。以下是一个示例: importjava.util.regex.Matcher;importjava.util.regex.Pattern;publicclassMain{publicstaticvoidmain(String[]args){Stringtext="Hello, world!";Stringpattern="hello";Stringreplacement="Hi";Patternp=Pattern.compile(patte...
