I assume that what you actually need is a java.sql.Array, since you mention jdbc and setArrayin some of your comments.
我假设你真正需要的是 a java.sql.Array，因为你提到了 jdbc 和setArray你的一些评论。
Three options:
三个选项：
- Try
Connection.createArrayOf(). This might or might not be available, depending on the JDBC driver you are using. - Write your own class that implements
java.sql.Array. Here is an examplefor PostgreSQL. - Some implementations, such as Oracle's, provide utility methods to work with arrays. Check the documentation of your JDBC driver.
- 试试
Connection.createArrayOf()。这可能可用也可能不可用，具体取决于您使用的 JDBC 驱动程序。 - 编写自己的类来实现
java.sql.Array. 这是PostgreSQL的示例。 - 一些实现，例如Oracle 的，提供了使用数组的实用方法。检查 JDBC 驱动程序的文档。

The Arrayclass is not an actual array. Instead it is a helper class that has static methods to help with arrays.
的Array类不是一个实际的数组。相反，它是一个辅助类，具有用于帮助处理数组的静态方法。
You may be looking to use ArrayListor something like it. You could use it using List<String> asd = Arrays.asList(time)
您可能正在寻找使用ArrayList或类似的东西。你可以使用它List<String> asd = Arrays.asList(time)

Arrayis an interface, not a class. Are you referring to ArrayList?!
Array是一个接口，而不是一个类。你指的是ArrayList？！
Here is your answer: Create ArrayList from array
这是您的答案：从数组创建 ArrayList
new ArrayList<Element>(Arrays.asList(array))
new ArrayList<Element>(Arrays.asList(array))
