Java Stream 메모

1. Int 배열을 Set으로

int[] intArray = {1, 2, 3, 4, 5};
Set<Integer> intSet = Arrays.stream(intArray).boxed().collect(Collectors.toSet());
System.out.println(intSet);

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

2. String 배열을 Set으로 

String[] strArray = {"apple", "banana", "mango"};
Set<String> strSet = Arrays.stream(strArray).collect(Collectors.toSet());
System.out.println(strSet);

-> [banana, apple, mango]
