如何使用正则表达式将字符串分割为前面的0 ?

时间:2021-12-25 02:08:20

How can I split a string A000101 as A000 and 101 , 000101 as 000 and 101 using the same regular expression.

我如何使用相同的正则表达式将字符串A000101作为A000和101、000101和101分开。

I tried with something like this "A000101".split("(?<=\\D)(?=\\d)|(?<=\\d)(?=\\D)&(?!=0)") but output is A and 000101

我试着用这样.split(“A000101(? < = \ \ D)(? = \ \ D)|(? < = \ \ D)(? = \ \ D)&(? ! = 0)”),但输出是一个和000101个

Can I get A0000 and 0 from A00000 using the same logic ?

我能用同样的逻辑从A00000中得到A0000和0吗?

It seems easier to me to use a Matcher instead of split:

对我来说,使用一个Matcher而不是split:

String str = "A000101";
Pattern p = Pattern.compile("([^1-9]*)([1-9]\\d*)");
Matcher m = p.matcher(str);
if (m.matches()) {
    String prec = m.group(1);
    String post = m.group(2);
}

You may try this pattern as well:

你也可以试试这个模式:

([^0]*0*)(\d+)

Each group should give you one part of the string that you want in split.

每个组应该给你一个你想要分割的字符串的一部分。
