推荐答案

您可以尝试拆分正则表达式，例如(?< = \ D)(?= \ d).试试这个:

You could try to split on a regular expression like (?<=\D)(?=\d). Try this one:

String str = "abcd1234";
String[] part = str.split("(?<=\\D)(?=\\d)");
System.out.println(part[0]);
System.out.println(part[1]);

将输出

abcd
1234

您可以使用 Integer.parseInt(part [1])将数字字符串解析为Integer.

You might parse the digit String to Integer with Integer.parseInt(part[1]).
