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.

Java Predicate lambda example Of course, if you're learning about the Java 8 Predicate interface, you're most likely interested in how to use it in a lambda function. The goal of a lambda expression ...

Example UnaryOperator Lambda expression. If you implement the UnaryOperator interface with a complete Java class, it will create completely valid code, but it defeats the purpose of working with a ...
