  - exclude
```
public static int[] exclude(int[] elements,
                            int[] excludedElements)
```
    Creates an array with the same order and elements as the original, except the excluded ones. For example, if elements is [0, 5, 3, 2, 5, 2], and excluded elements is [5, 6], then [0, 3, 2, 2] is the result.
    
    Parameters:
    
    elements - all elements. Must not be null
    
    excludedElements - the ones which are be excluded (duplicates don't matter). Most not be null
    
    Returns:
    
    all elements except the ones that shall be excluded
  - contains
```
public static boolean contains(int[] elements,
                               int element)
```
    Checks whether the given element appears anywhere in the given array.
    
    Parameters:
    
    elements - all elements which are searched. Must not be null
    
    element - the element for which is searched
    
    Returns:
    
    whether the given element appears in the given elements at any arbitrary index
  - indexOf
```
public static java.util.OptionalInt indexOf(int[] elements,
                                            int element)
```
    Parameters:
    
    elements -
    
    element -
    
    Returns:
  - containsDuplicates
