Converting Between List and Array

1. Array to List

// Convert to an unmodifiable list

// First copy the original array
// Then convert it to a list
// Finally convert it to an unmodifiable list
Collections.unmodifiableList(Arrays.asList(Arrays.copyOf(arrays, arrays.length)));

// Convert to a mutable list
Arrays.stream(Arrays.copyOf(arrays, arrays.length)).collect(Collectors.toList());

2. List to Array

list.toArray();
