类名称：String
方法名：replaceAll

String.replaceAll介绍

[英]Replaces each substring of this string that matches the given regular expression with the given replacement.

An invocation of this method of the form str.replaceAll(regex, repl) yields exactly the same result as the expression

java.util.regex.Pattern. java.util.regex.Pattern#compile(regex). java.util.regex.Pattern#matcher(java.lang.CharSequence)(str). java.util.regex.Matcher#replaceAll(repl)

Note that backslashes () and dollar signs ($) in the replacement string may cause the results to be different than if it were being treated as a literal replacement string; see java.util.regex.Matcher#replaceAll. Use java.util.regex.Matcher#quoteReplacement to suppress the special meaning of these characters, if desired.
[中]将此字符串中与给定regular expression匹配的每个子字符串替换为给定的替换项。
调用str.replaceAll（regex，repl）形式的此方法会产生与表达式完全相同的结果
JAVAutil。正则表达式。图案JAVAutil。正则表达式。模式#编译（regex）。JAVAutil。正则表达式。模式匹配器（java.lang.CharSequence）（str）。JAVAutil。正则表达式。Matcher#replaceAll（repl）
请注意，替换字符串中的反斜杠（\）和美元符号（$）可能会导致结果不同于将其视为文字替换字符串时的结果；参见java。util。正则表达式。Matcher#replaceAll。使用java。util。正则表达式。Matcher“quoteReplacement，如果需要，用于抑制这些字符的特殊含义。
