e359. Sorting an Array

    int[] intArray = new int[] {4, 1, 3, -23};
    Arrays.sort(intArray);
    // [-23, 1, 3, 4]
    
    String[] strArray = new String[] {"z", "a", "C"};
    Arrays.sort(strArray);
    // [C, a, z]
    
    // Case-insensitive sort
    Arrays.sort(strArray, String.CASE_INSENSITIVE_ORDER);
    // [a, C, z]
    
    // Reverse-order sort
    Arrays.sort(strArray, Collections.reverseOrder());
    // [z, a, C]
    
    // Case-insensitive reverse-order sort
    Arrays.sort(strArray, String.CASE_INSENSITIVE_ORDER);
    Collections.reverse(Arrays.asList(strArray));
    // [z, C, a]
