Class MultiplicationOf

java.lang.Object

java.lang.Number

org.cactoos.scalar.NumberEnvelope

org.cactoos.scalar.MultiplicationOf

All Implemented Interfaces:

Serializable, Scalar<Double>

public final class MultiplicationOf
extends NumberEnvelope

Multiplication result of numbers.

Here is how you can use it to multiply numbers:

 int multiplication = new MultiplicationOf(1, 2, 3, 4).intValue();
 long multiplication = new MultiplicationOf(1L, 2L, 3L).longValue();
 double multiplication = new MultiplicationOf(2.3, 3.4, 4.0).doubleValue();
 

This class implements Scalar, which throws a checked Exception. This may not be convenient in many cases. To make it more convenient and get rid of the checked exception you can use the UncheckedScalar decorator. Or you may use IoCheckedScalar to wrap it in an IOException.

There is no thread-safety guarantee.

0.49.2
