Modifier and Type	Method and Description
public static <T> boolean	Returns: True if there is at least one element that's common to both Collections, ie. that is contained in both of them. anyValuesInCommon(Collection<T> c1, Collection<T> c2) Method that can be used to efficiently check if 2 collections share at least one common element.

public static Object	growArrayBy50Pct(Object arr)
public static Object	growArrayToAtLeast(Object arr, int minLen) Method similar to `growArrayBy50Pct`, but it also ensures that the new size is at least as big as the specified minimum size.
public static Object	growArrayToAtMost(Object arr, int maxLen) Method similar to `growArrayBy50Pct`, but it also ensures that the new size is no bigger than specific maximum size.

public void remove() Overrides default java.util.Iterator.remove. Doc from java.util.Iterator.remove. Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to `next`. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method, unless an overriding class has specified a concurrent modification policy. The behavior of an iterator is unspecified if this method is called after a call to the `forEachRemaining` method. Annotations @Override
