我需要 split()方法的帮助。 我有以下字符串:
I need help with the split() method. I have the followingString:
String values = "0|0|0|1|||0|1|0|||";我需要将值放入数组中。有3种可能的字符串:0,1和
I need to put the values into an array. There are 3 possible strings: "0", "1", and ""
我的问题是,当我尝试使用 split() :
My problem is, when i try to use split():
String[] array = values.split("\\|");我的值仅保存到最后0.看起来像|||部分被修剪。 我做错了什么?
My values are saved only until the last 0. Seems like the part "|||" gets trimmed. What am i doing wrong?
谢谢
推荐答案String.split(String regex) (强调我的):
This behavior is explicitly documented in String.split(String regex) (emphasis mine):
此方法的作用就像通过调用给定表达式和limit参数为零的双参数split方法一样。因此,尾随空字符串在结果数组中不包含。
如果你想要包含那些尾随的空字符串,你需要使用 String.split(String regex,int limit) ,第二个参数为负值( limit ):
If you want those trailing empty strings included, you need to use String.split(String regex, int limit) with a negative value for the second parameter (limit):
String[] array = values.split("\\|", -1);更多推荐
Java将字符串拆分为数组
