我们可以用正则表达式/匹配来代替 Java 中的 endsWith()方法使用正则表达式 使用匹配 方法1: 使用正则表达式正则表达式(简称 Regex)是一个定义字符串模式的应用编程接口,可用于在 Java 中搜索、操作和编辑字符串。电子邮件验证和密码是字符串的几个领域,Regex 被广泛用于定义约束。正则表达式在 java.util.regex 包下...
split(String regex, int limit): The limit parameter defines the number of records in the result string array. split(String regex): returns the string array with all the substrings around the regex matches. Recommended Reading:Java String split() Method 推荐阅读:Java String split()方法 (17. ...

The startsWith and endsWith methods enable you to test whether a path begins or ends with a particular string. These methods are easy to use. For example: Path path = ...; Path otherPath = ...; Path beginning = Paths.get("/home"); Path ending = Paths.get("foo"); if (path....
split(String regex, int limit) Splits this string around matches of the given regular expression. boolean startsWith(String prefix) Tests if this string starts with the specified prefix. boolean startsWith(String prefix, int toffset) Tests if the substring of this string beginning at the sp...
