若lookingAt()方法返回true,matcher调用group()可以返回lookingAt()方法找到的匹配模式的子序列。 函数:public boolean find(int start); 作用:matcher调用该方法判断input从参数start指定的位置开始是否有和regex匹配的子序列,参数start取值为0时,该方法和lookingAt()的功能相同。 函数:public String replaceAll(String ...

startat 參數會定義第一個分隔符開始搜尋的點(這可用於略過前置空格符)。 如需startat的詳細資訊,請參閱 Match(String, Int32)的一節。 如果字串中 count+1 位置找不到相符專案,此方法會傳回包含 input 字串的一個元素陣列。 如果找到一或多個相符專案,則傳回陣列的第一個元素會包含字元串的第一個部分,...
