Java String.split() method 有如下几种特殊情况: 1. 分隔符出现在首尾 1publicstaticvoidmain(String args[]) {2String Str =newString("aba");3System.out.println("Start :");45for(String retval: Str.split("a")) {6System.out.println("^"+ retval + "^");7}8System.out.println("Stop");...
The split() method splits a string into an array of substrings using a regular expression as the separator.If a limit is specified, the returned array will not be longer than the limit. The last element of the array will contain the remainder of the string, which may still have ...

在开发中,建议开发者多进行性能测试,并根据场景需求选择最优方案,以便于打造更高效的 Java 应用。以下是一个简单的序列图,展示了String.split()方法的调用流程: UserSplitMethodUserallocate arrayreturn String array 希望这篇文章能够帮助开发者更好地理解和优化 Java 中的字符串分割操作,提高编程效率。
Splits this string around matches of the given regular expression. This method works as if by invoking the two-argument #split(String, int) split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array. The string...
Java中split方法的细节问题。 先看一段代码: + View Code 你会觉得长度应该不是1,那是为什么呢? 看一下jdk中关于方法的说明。 split publicString[]split(Stringregex) Splits this string around matches of the givenregular expression. This method works as if by invoking the two-argumentsplitmethod with...
It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead. 参考:https://docs.oracle.com/en/java/javase/15/docs/api/java.base/java/util/StringTokenizer.html StringTokenizer 原来是一个遗留类,并未被废弃,只是出于兼容性原因而被...
