推荐答案

您可以尝试在正则表达式上进行拆分，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]);

会输出

abcd
1234

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

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