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.

The goal of a lambda expression in Java is to implement a single method. All Java methods have an argument list and a body, so it should come as no surprise that these two elements are an important ...

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.

Here is a Consumer interface and lambda expression example: Consumer<Long> conciseLambda = (Integer t) -> System.out.println(t*t); conciseLambda.accept(new Long(10)); Again, the difference between the ...
