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 ...
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 "boo:and:foo", for example, yields the following results with ...

StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. 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...

publicString[] split(String regex,intlimit) 如果limit是负数,那么它会尽可能匹配到所有的这个数组的个数,如果是0那么尽可能匹配出现的元素,但是空字符串将会被就丢弃,但我们不希望它丢弃,因为丢弃就意味着有业务字段缺失,所以来看下最终的写法: Java代码 ...
