Uses of Class java.lang.Double (Java SE 12 & JDK 12 )

Packages that use Double
Package	Description
java.lang	Provides classes that are fundamental to the design of the Java programming language.
java.util	Contains the collections framework, some internationalization support classes, a service loader, properties, random number generation, string parsing and scanning classes, base64 encoding and decoding, a bit array, and several miscellaneous utility classes.
java.util.stream	Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.
javax.management.openmbean	Provides the open data types and Open MBean descriptor classes.

Uses of Double in java.lang

Fields in java.lang with type parameters of type Double
Modifier and Type	Field	Description
`static Class<Double>`	Double.`TYPE`	The `Class` instance representing the primitive type `double`.

Methods in java.lang that return Double
Modifier and Type	Method	Description
`Double`	Double.`resolveConstantDesc(MethodHandles.Lookup lookup)`	Resolves this instance as a `ConstantDesc`, the result of which is the instance itself.
`static Double`	Double.`valueOf(double d)`	Returns a `Double` instance representing the specified `double` value.
`static Double`	Double.`valueOf(String s)`	Returns a `Double` object holding the `double` value represented by the argument string `s`.

Methods in java.lang that return types with arguments of type Double
Modifier and Type	Method	Description
`Optional<Double>`	Double.`describeConstable()`	Returns an `Optional` containing the nominal descriptor for this instance, which is the instance itself.

Methods in java.lang with parameters of type Double
Modifier and Type	Method	Description
`int`	Double.`compareTo(Double anotherDouble)`	Compares two `Double` objects numerically.

Uses of Double in java.util

Methods in java.util that return Double
Modifier and Type	Method	Description
`default Double`	PrimitiveIterator.OfDouble.`next()`	Returns the next element in the iteration.

Method parameters in java.util with type arguments of type Double
Modifier and Type	Method	Description
`default void`	PrimitiveIterator.OfDouble.`forEachRemaining(Consumer<? super Double> action)`	Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
`default void`	Spliterator.OfDouble.`forEachRemaining(Consumer<? super Double> action)`	Performs the given action for each remaining element, sequentially in the current thread, until all elements have been processed or the action throws an exception.
`default boolean`	Spliterator.OfDouble.`tryAdvance(Consumer<? super Double> action)`	If a remaining element exists, performs the given action on it, returning `true`; else returns `false`.

Uses of Double in java.util.stream

Methods in java.util.stream that return types with arguments of type Double
Modifier and Type	Method	Description
`static <T> Collector<T,?,Double>`	Collectors.`averagingDouble(ToDoubleFunction<? super T> mapper)`	Returns a `Collector` that produces the arithmetic mean of a double-valued function applied to the input elements.
`static <T> Collector<T,?,Double>`	Collectors.`averagingInt(ToIntFunction<? super T> mapper)`	Returns a `Collector` that produces the arithmetic mean of an integer-valued function applied to the input elements.
`static <T> Collector<T,?,Double>`	Collectors.`averagingLong(ToLongFunction<? super T> mapper)`	Returns a `Collector` that produces the arithmetic mean of a long-valued function applied to the input elements.
`Stream<Double>`	DoubleStream.`boxed()`	Returns a `Stream` consisting of the elements of this stream, boxed to `Double`.
`static <T> Collector<T,?,Double>`	Collectors.`summingDouble(ToDoubleFunction<? super T> mapper)`	Returns a `Collector` that produces the sum of a double-valued function applied to the input elements.

Uses of Double in javax.management.openmbean

Fields in javax.management.openmbean with type parameters of type Double
