哥们，你这样的问题是ChatGPT最擅长的，几秒内就搞定，还带测试用例，要是不对就自己改进一下吧，或者Let's think step by step一下

Here's an example implementation of a Java method that takes a list of arrays as input, removes duplicate arrays and returns the updated list:

java
Copy code
import java.util.*;

public class ArrayDuplicateRemover {

    public static List<int[]> removeDuplicateArrays(List<int[]> inputList) {
        
        // create a set to store unique arrays
        Set<String> set = new HashSet<>();
        
        // create a list to store non-duplicate arrays
        List<int[]> outputList = new ArrayList<>();
        
        // iterate over the input list
        for (int[] arr : inputList) {
            // sort the array to make sure that arrays with the same elements in a different order are considered equal
            Arrays.sort(arr);
            // convert the array to a string and add it to the set
            String arrString = Arrays.toString(arr);
            if (!set.contains(arrString)) {
                // if the set does not already contain the array, add it to the set and the output list
                set.add(arrString);
                outputList.add(arr);
            }
        }
        
        return outputList;
    }

}
To use this method, you can create an instance of the ArrayDuplicateRemover class and call the removeDuplicateArrays method, passing in the list of arrays as a parameter. Here's an example:

java
Copy code
public static void main(String[] args) {
    List<int[]> inputList = new ArrayList<>();
    inputList.add(new int[]{1, 2, 3, 4});
    inputList.add(new int[]{4, 6, 7, 8});
    inputList.add(new int[]{3, 2, 4, 1});
    inputList.add(new int[]{1, 2, 3, 4});
    List<int[]> outputList = ArrayDuplicateRemover.removeDuplicateArrays(inputList);
    for (int[] arr : outputList) {
        System.out.println(Arrays.toString(arr));
    }
}
