The
LongSupplier 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 long value.
The lambda expression assigned to an object of LongSupplier type is used to define its
getAsLong() which eventually applies the given operation on its argument. It is similar to using an object of type
Supplier<Long>

The LongSupplier interface consists of the only one function:

This method does not take in any value but produces a long-valued result.
Syntax:
long getAsLong()
Return Value: This method returns
a long value.
Below is the code to illustrate getAsLong() method:
