Thegflag stands forglobaland replaces all occurrences of the matched string. If you only want to do a case-insensitive replacement the first time the regular expression matches the string, remove thegflag: index
String input = "Hello World! hello java."; String regex = "hello"; String replacement = "hi"; Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE); Matcher matcher = pattern.matcher(input); String result = matcher.replaceAll(replacement); System.out.println(result); // 输出:...
QString QString::replace(const QString &before, const QString &after, Qt::CaseSensitivity cs = Qt::CaseSensitive) 其中,before表示要被替换的子串,after表示替换后的子串,cs表示匹配时是否区分大小写。如果cs为Qt::CaseSensitive,则表示区分大小写;如果cs为Qt::CaseInsensitive,则表示不区分大小写。 replace...

CASE_INSENSITIVE : 这个标志就代表匹配时不区分大小写。 1. 2. 3. 4. 5. 6. 7. Pattern里的match() (匹配的方法): 可以看到,在这里最终调用的其实是Matcher类的Matcher()方法。这里关于源码,其实我们也没有必要完全看懂,这个东西的完全实现还是有一点复杂的。
WithNode.js 16, this package is partly moot as there is now aString#replaceAllmethod. However, it does not have acaseInsensitiveoption. Install $ npm install replace-string Usage importreplaceStringfrom'replace-string';conststring='My friend has a 🐑. I want a 🐑 too!';replaceString(str...
String对象是不可变的 String类中每一个看起来会修改String值的方法 实际上都是创建了一个全新的String对象 以包含修改后的字符串内容 而最初的String对象则丝毫未动 当把q传给upcase()方法时 实际传递的是引用的一个拷贝 其实 每当把String对象作为方法的参数时 都会复制一份引用 而该引用所指的对象其实一直待在...

return new string(chars, 0, count); } 在研究String.IndexOf为什么那么衰的过程中,发现原来.NET Framework提供了case-insensitive的IndexOf的说。这样一来就可以不用String.ToUpper了 ,继续改造ReplaceEx得到ReplaceEx3: private static string ReplaceEx3(string original, string pattern, string replacement) ...
