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. T
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 ...

1.在程序开发中,有些时候我们需要对字符串的截取和分割,String类提供了substring()方法是截取字符串的一部分,split()方法是字符串以给定的字符进行分割成字符串数组。 2.字符串截取方法和分割方法 public String substring(int index)方法:截取字符串是从索引的位置开始一直到末尾,方法返回值是新字符串。
