Java Array Sorting Java8

//1. Natural ordering

User[] sortedUserArray = Stream.of(userArray)
            .sorted()
            .toArray(User[]::new);

//2. Reverse ordering

User[] sortedUserArray = Stream.of(userArray)
            .sorted(Comparator.reverseOrder())
            .toArray(User[]::new);

//3. Custom Sorting

Comparator nameComparator = Comparator.comparing(Employee::getName)
	.thenComparing(Employee::getId)

User[] sortedUserArray = Stream.of(userArray)
            .sorted(nameComparator)
            .toArray(User[]::new);
