The
DoubleSupplier Interface is a part of the
java.util.function package which has been introduced since Java 8, to implement
functional programming in Java. It represents a function which does not take in any argument but produces a double value.
The lambda expression assigned to an object of DoubleSupplier type is used to define its
getAsDouble() which eventually applies the given operation on its argument. It is similar to using an object of type
Supplier<Double>
