List<Integer> ids = Arrays.asList(modifyId);

As an AI language model, I cannot determine the exact context of this code snippet. However, I can provide some general explanation.

This line of code creates a new `List<Integer>` object and assigns it to the variable `ids`. The elements of this list are taken from an array `modifyId`, which is passed as an argument to the `Arrays.asList()` method.

The `Arrays.asList()` method is a static method that returns a fixed-size list backed by the specified array. In this case, the `modifyId` array is used to create a new list of integers.

Note that any changes made to the elements of this list will also affect the corresponding elements in the `modifyId` array. Similarly, any changes made to the array itself will also affect the list.
