Return	Method	Summary
static<T extends Object & Comparable<? super T>>T	max(Collection<? extends T> coll)	Returns the maximum element of the given collection, according to the natural ordering of its elements.
static<T> T	max(Collection<? extends T> coll, Comparator<? super T> comp)	Returns the maximum element of the given collection, according to the order induced by the specified comparator.
static<T extends Object & Comparable<? super T>>T	min(Collection<? extends T> coll)	Returns the minimum element of the given collection, according to the natural ordering of its elements.
static<T> T	min(Collection<? extends T> coll, Comparator<? super T> comp)	Returns the minimum element of the given collection, according to the order induced by the specified comparator.
