What Is Lambda Expression?
LambdaCalculator.java - Lambda Expression Example
Lambda Expression Syntax Options
Lambda Expression as Method Reference
Method Reference Example - LambdaMethodRefernce.java
Lambda Expression Stream Pipeline Operations
- A functional interface is a single abstract method interface.
- A lambda expression is a shorthand form of a special anonymous class that implements a functional interface.
- A method expression is a shorthand form of a special lambda expression that a single invocation of a static method.
- The best places to use lambda expressions are in stream pipeline operations.
- Lambda expressions, method references and stream pipeline operations are introduced in Java 8.
