This tutorial demonstrates the power of lambda expressions by contrasting implementations of a mathematical example using C++, Java without lambdas, and Java 8 with lambda expressions.

Like C# lambda expressions, Java 8 lambda expressions tie an argument list to a body. For example, (int x) -> x * x specifies an integer parameter that’s named x and returns the value of x squared.

Consternation over Java's lambda syntax is the perfect example of how Java's evolution and incremental improvements have created a community of spoiled programmers.

Here’s an example of how a Function and lambda expression work together: Function<Integer, String> verboseLambda = (Integer x)-> { return Integer. toString (x*x); }; System.

Amazon Web Services announced that cloud developers can now use Java for writing Lambda functions, which provide event-driven functionality while taking care of needed compute resources.

Instana announces the availability of automated distributed tracing for Lambda functions written in Java or Go.

While the Java support is a significant milestone in the evolution of AWS Lambda, Amazon has been continuously adding features to the microservices platform.
