publicbooleanmatches(Stringregex) 1. 其中,regex参数是一个字符串,表示要匹配的正则表达式。 要匹配一个数字,我们可以使用正则表达式\d+。该正则表达式表示匹配一个或多个数字。接下来,我们将通过一个示例来演示如何使用matches方法匹配数字。 publicclassMatchNumberExample{publicstaticvoidmain(String[]args){Stringnum...

Java matches() 方法 Java String类 matches() 方法用于检测字符串是否匹配给定的正则表达式。 调用此方法的 str.matches(regex) 形式与以下表达式产生的结果完全相同: Pattern.matches(regex, str) 语法 public boolean matches(String regex) 参数 regex --
