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.

The return keyword on the right-hand side of the lambda expression is the key to the Function interface.. The Consumer interface function. In contrast to the Function interface, the Consumer interface ...

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. Share this item with your network: ...
