例如我有这个数组

String[] mailToCc = {"[email protected]; [email protected];", "[email protected]"};

第一个元素是 2 封邮件，末尾有分号。我想要的是将这两个元素分开（它们可以在数组的任何元素上找到，并不总是第一个）并将它们像新元素一样添加到原始数组中。它应该是这样的

["[email protected]", "[email protected]", "[email protected]"];

这是我的尝试

import java.util.ArrayList;

import java.util.Arrays;
public class Main
{
    public static void main(String[] args) {
        ArrayList<String> updatedMailToCc = new ArrayList<>();
        String[] mailToCc = {"[email protected]; [email protected];", "[email protected]"};

        for (String element : mailToCc) {
            String[] splitElements = element.split(";");

            // Add the original element itself
            updatedMailToCc.add(element);

            // If it could be split, add each part as a new element
            if (splitElements.length > 1) {
                 updatedMailToCc.addAll(Arrays.asList(splitElements));
            }
       }

       // Convert the ArrayList back to an array if needed
       mailToCc = updatedMailToCc.toArray(new String[0]);

       // Print the updated array
       System.out.println("resultado =" + Arrays.toString(mailToCc));
    }
}

但我没有得到我需要的东西，而是得到了这个结果

["[email protected]; [email protected];", "[email protected]",  "[email protected]", "[email protected]"]
