DoubleStream generate() method in Java

The generate() method of the DoubleStream class 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, the parameter s is the DoubleSupplier for generated elements. The DoubleSupplier is a supplier of double-valued results. To use the DoubleStream class in Java, import the following package

import java.util.stream.DoubleStream;

The following is an example to implement DoubleStream generate() method in Java

      doubleStream.limit(5).forEach(System.out::println);
   }
}
