Bug Report for https://neetcode.io/problems/range-sum-query-immutable

Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.

I think there's a bug with Java. When I run the code I see this error:

Main.java:-4: error: package javafx.util does not exist
import javafx.util.*;
^
1 error

But I don't have any imports in the code. And I don’t think any kind of import is needed for this code.
The problem occurs both on Run and on Submit.

class NumArray {
    int[] prefix;

    public NumArray(int[] nums) {
        this.prefix = new int[nums.length];
        int tot = 0;
        for (int i = 0; i < nums.length; i++) {
            tot += nums[i];
            prefix[i] = tot;
        }
    }
    
    public int sumRange(int left, int right) {
        int preRight = prefix[right];
        int preLeft = left > 0 ? prefix[left - 1] : 0;
        return preRight - preLeft;
    }
}

/**
 * Your NumArray object will be instantiated and called as such:
 * NumArray obj = new NumArray(nums);
 * int param_1 = obj.sumRange(left,right);
 */

AI suggested fix says:

The compilation error was not actually in your logic, but rather an environment issue where the javafx.util.* package was missing from the execution environment.
