Modifier and Type	Class and Description
class	Boolean The Boolean class wraps a value of the primitive type boolean in an object.
class	Byte The Byte class wraps a value of primitive type byte in an object.
class	Character The Character class wraps a value of the primitive type char in an object.
class	Double The Double class wraps a value of the primitive type double in an object.
class	Enum<E extends Enum<E>> This is the common base class of all Java language enumeration types.

Uses of Comparable in java.util

Methods in java.util with type parameters of type Comparable

Modifier and Type	Method and Description
static <T,U extends Comparable<? super U>> Comparator<T>	Comparator.comparing(Function<? super T,? extends U> keyExtractor) Accepts a function that extracts a Comparable sort key from a type T, and returns a Comparator<T> that compares by that sort key.
static <K extends Comparable<? super K>,V> Comparator<Map.Entry<K,V>>	Map.Entry.comparingByKey() Returns a comparator that compares Map.Entry in natural order on key.
static <K,V extends Comparable<? super V>> Comparator<Map.Entry<K,V>>	Map.Entry.comparingByValue() Returns a comparator that compares Map.Entry in natural order on value.
static <T extends Comparable<? super T>> Comparator<T>	Comparator.naturalOrder() Returns a comparator that compares Comparable objects in natural order.
static <T extends Comparable<? super T>> Comparator<T>	Comparator.reverseOrder() Returns a comparator that imposes the reverse of the natural ordering.
default <U extends Comparable<? super U>> Comparator<T>	Comparator.thenComparing(Function<? super T,? extends U> keyExtractor) Returns a lexicographic-order comparator with a function that extracts a Comparable sort key.
