Can a java lambda have more than 1 parameter?

Question

In Java, is it possible to have a lambda accept multiple different types?

I.e: Single variable works:

    Function  adder = i         


        

Answer 1

To make the use of lambda : There are three type of operation:
1. Accept parameter --> Consumer
2. Test parameter return boolean --> Predicate
3. Manipulate parameter and return value --> Function

Java Functional interface upto two parameter:
Single parameter interface
Consumer
Predicate
Function

Two parameter interface
BiConsumer
BiPredicate
BiFunction

For more than two, you have to create functional interface as follow(Consumer type):

@FunctionalInterface
public interface FiveParameterConsumer {
    public void accept(T t, U u, V v, W w, X x);
}
