我想分成`String和`int`数组Java

我有文本数据,我想拆分String和int数组Java

String text = "one1two20three300four4000";

期望的输出:

String str[] = "one","two","three","four";

int num[] = 1,20,300,4000;

这个适用于Java:

public static void main(String[] args) {
    String text = "one1two20three300four4000";
    String arr1[] = text.replaceFirst("^\\d+", "").split("\\d+");
    String arr2[] = text.replaceFirst("^\\D+", "").split("\\D+");
    System.out.println(Arrays.toString(arr1));
    System.out.println(Arrays.toString(arr2)); // parse each value as an in using Streams (preferably) or a loop.
}

O/P:

[
1,2,3,4 ] [1,20,300,4000]

PS:在java 8中int[] arr2Int = Arrays.stream(arr2).mapToInt(Integer::parseInt).toArray();用于将String数组转换为int数组.
