Are lambda expressions objects in Java?
Yes, any lambda expression is an object in Java. It is an instance of a functional interface. We have assigned a lambda expression to any variable and pass it like any other object.
Syntax
(parameters) -> expression
or
(parameters) -> { statements; }
In the below example, how a lambda expression has assigned to a variable and how it can be invoked.
Example
@FunctionalInterface
interface ComparatorTask {
public boolean compare(int t1, int t2);
}
public class LambdaObjectTest {
public static void main(String[] args) {
ComparatorTask ctask = (int t1, int t2) -> {return t1 > t2;}; // lambda expression
boolean b = ctask.compare(10, 3);
System.out.println("The result is: " + b);
}
}
Output
The result is: true
