How to Remove Duplicate Emails from an Array Using Java Set?

Using Java Set to Remove Duplicate Emails from an Array

In your code, you need to prevent duplicate email addresses from being stored in the array address. To achieve this, you can utilize a Java Set data structure, which automatically eliminates duplicates.

Implementation:

Convert the address array to a Set using the Arrays.asList() method:

Set<String> emailSet = new HashSet<>(Arrays.asList(address));

This will create a Set named emailSet containing all unique email addresses.

Modified Code:

// ...

// Convert array to a set to remove duplicates
Set<String> emailSet = new HashSet<>(Arrays.asList(address));

// ...

By converting the array to a Set, you ensure that only unique emails are retained, effectively eliminating duplicates in your output.
