Write a method named remove Duplicates that accepts as a parameter a List of integers, and modifies it by removing any duplicates. Note that the elements of the list are not in any particular order, so the duplicates might not occur consecutively. You should retain the original relative order of the elements. Use a Set as auxiliary storage to help you solve this problem. For example, if a list named list stores [4, 0, 2, 9, 4, 7, 2, 0, 0, 9, 6, 6], the call of removeDuplicates (list); should modify it to store [4, 0, 2, 9, 7, 6].

You only need to write a Java method as described, not a complete
**Description:**
In this section, we will explore how to write a method named `removeDuplicates` that accepts a `List` of integers as a parameter and modifies it by removing any duplicates. This process involves understanding that elements in the list might not occur consecutively since they are not in any particular order. The task is to ensure the original relative order of the elements is retained.
For effective implementation, a `Set` should be used as auxiliary storage. A `Set` inherently does not allow duplicate values, making it an excellent choice for this problem.
**Example Implementation:**
Consider a list named `list` with the following integers:
```
[4, 0, 2, 9, 4, 7, 2, 0, 9, 6, 6]
```
Upon calling the method `removeDuplicates(list)`, the list should be modified to store:
```
[4, 0, 2, 9, 7, 6]
```
In this example, duplicates such as `4`, `2`, `0`, and `9` are removed while maintaining their first occurrence and the original order. Using a `Set` for storage during this process efficiently handles and removes duplicate entries.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdf909276-6ad3-4144-b98c-235c5a32e436%2F43c4bbbc-d2df-4918-ab79-1c9a337dc3ea%2Fmhs1n99_processed.jpeg&w=3840&q=75)
