java - 如何在java中分割电子邮件ID

Question

在拆分电子邮件 ID 时获取此消息[Ljava.lang.String;@776a35. 为什么我无法理解。

        String[] For_split_email=email.split("[@._]");
        for (int j = 0; j <= For_split_email.length - 1; j++) {
        System.out.println("splited emails----------"+For_split_email[j]);
         }

Answer 1

你的代码非常适合我。但应该是j <= For_split_email.length - 1在 for 循环中。

    String email = "test@test.de";
    String[] For_split_email = email.split("[@._]");
    for (int j = 0; j <= For_split_email.length - 1; j++)
    {
        System.out.println("splited emails----------" + For_split_email[j]);
    }

输出:

splited emails----------test
splited emails----------test
splited emails----------de
