int array to set in java

To convert an array of integers to a Set in Java, you can use the Collectors.toSet() method of the Collectors class. This method returns a Set that contains the elements of the array.

Here is an example of how to convert an array of integers to a Set:

int[] arr = {1, 2, 3, 4, 5};

Set<Integer> set = Arrays.stream(arr)
    .boxed()
    .collect(Collectors.toSet());

// set is {1, 2, 3, 4, 5}

In this example, the array is first converted to a stream of integers using the Arrays.stream() method. The boxed() method is used to convert the stream of primitive int values to a stream of Integer objects. Finally, the Collectors.toSet() method is used to create a Set that contains the elements of the array.

For more information on the Collectors.toSet() method in Java, you can refer to the Java documentation.
