The DoubleStream.generate() method returns an infinite sequential unordered stream where each element is generated by the provided DoubleSupplier.

The syntax is as follows −

static DoubleStream generate(DoubleSupplier s)

Here, s is the DoubleSupplier for generated elements. The DoubleSupplier represents a supplier of double-valued results.

To use the DoubleStream class in Java, import the following package −
