removing duplicate elements from an unsorted array in java can be accomplished in several ways. below, i'll provide a tutorial on different methods to achieve this, along with a code example for each method.

method 1: using a hashset

the easiest and most efficient way to remove duplicates from an array is to use a `hashset`. a `hashset` stores only unique elements, so when you add elements from the array, it automatically handles duplicates for you.

code example

method 2: using a list and retaining order

if you want to preserve the order of the elements while removing duplicates, you can use a `linkedhashset`, which maintains insertion order.

code example

method 3: using sorting and iteration

another method is to sort the array first and then iterate through it to remove duplicates. this method does not preserve the original order of the elements.

code example

conclusion

in summary, there are various methods to remove duplicates from an unsorted array in java:

1. *using `hashset`* - simple and efficient, but does not maintain order.
2. *using `linkedhashset`* - maintains insertion order while removing duplicates.
3. *sorting and iteration* - removes duplicates but does not maintain original order.

you can choose the method that best fits your needs based on whether you want to maintain order and the efficiency required for your application.
