java program

For the partial implementation of the class IntArrayList below, implement the method removeDuplicates.

After a call to the method removeDuplicates, the array designated by the instance variable elems contains no duplicated values.

The method keeps the leftmost value for each duplicated pairs.

Finally, the size of the array designated by elems must be exactly that of the number of unique values.

The execution of the method IntArrayList.test prints the following:

[2, 1, 1, 5, 3, 1, 2, 4]

[2, 1, 5, 3, 4]
