All Methods Static Methods Concrete Methods
Modifier and Type	Method and Description
`static DoubleStream.Builder`	`builder()` Returns a builder for a `DoubleStream`.
`static DoubleStream`	`concat(DoubleStream a, DoubleStream b)` Creates a lazily concatenated stream whose elements are all the elements of the first stream followed by all the elements of the second stream.
`static DoubleStream`	`empty()` Returns an empty sequential `DoubleStream`.
`static DoubleStream`	`generate(DoubleSupplier s)` Returns an infinite sequential unordered stream where each element is generated by the provided `DoubleSupplier`.
`static DoubleStream`	`iterate(double seed, DoubleUnaryOperator f)` Returns an infinite sequential ordered `DoubleStream` produced by iterative application of a function `f` to an initial element `seed`, producing a `Stream` consisting of `seed`, `f(seed)`, `f(f(seed))`, etc.

  - builder
```
public static DoubleStream.Builder builder()
```
    Returns a builder for a DoubleStream.
    
    Returns:
    
    a stream builder
  - empty
```
public static DoubleStream empty()
```
    Returns an empty sequential DoubleStream.
    
    Returns:
    
    an empty sequential stream
  - of
```
public static DoubleStream of(double t)
```
    Returns a sequential DoubleStream containing a single element.
    
    Parameters:
    
    t - the single element
    
    Returns:
    
    a singleton sequential stream
  - of
```
public static DoubleStream of(double... values)
```
    Returns a sequential ordered stream whose elements are the specified values.
    
    Parameters:
    
    values - the elements of the new stream
    
    Returns:
    
    the new stream
  - iterate
```
public static DoubleStream iterate(double seed,
                                   DoubleUnaryOperator f)
```
    Returns an infinite sequential ordered DoubleStream produced by iterative application of a function f to an initial element seed, producing a Stream consisting of seed, f(seed), f(f(seed)), etc.
    The first element (position 0) in the DoubleStream will be the provided seed. For n > 0, the element at position n, will be the result of applying the function f to the element at position n - 1.
    
    Parameters:
    
    seed - the initial element
    
    f - a function to be applied to the previous element to produce a new element
    
    Returns:
    
    a new sequential DoubleStream
  - generate
```
public static DoubleStream generate(DoubleSupplier s)
```
    Returns an infinite sequential unordered stream where each element is generated by the provided DoubleSupplier. This is suitable for generating constant streams, streams of random elements, etc.
    
    Parameters:
    
    s - the DoubleSupplier for generated elements
    
    Returns:
    
    a new infinite sequential unordered DoubleStream
  - concat
```
public static DoubleStream concat(DoubleStream a,
                                  DoubleStream b)
```
    Creates a lazily concatenated stream whose elements are all the elements of the first stream followed by all the elements of the second stream. The resulting stream is ordered if both of the input streams are ordered, and parallel if either of the input streams is parallel. When the resulting stream is closed, the close handlers for both input streams are invoked.
    Implementation Note:
    Use caution when constructing streams from repeated concatenation. Accessing an element of a deeply concatenated stream can result in deep call chains, or even StackOverflowError.
    
    Parameters:
    
    a - the first stream
    
    b - the second stream
    
    Returns:
    
    the concatenation of the two input streams
