Why Functional References are called “Lambda Expressions” in Java 8?

Many of us are very curious about the fact that why functional references introduced in Java 8 are know as Lambda Expressions. So let’s reveal the fact of word “Lambda Expressions” and make it very simple to understand.

This fact is very much related to the Evaluation process of any expression. Many of us may have solved the mathematical problems and while solving the problems we may have observed how we are reducing the mathematical expression to some values. Similarly we also may have observed in many programming languages how any expression is evaluated.

Java 8: Lambda Expressions

Java 8 is completing almost 2 years now and this topic is widely discussed on Internet now a days. Java was originally designed to work OOP as it was the primary paradigm for software development at that time. But today’s programming directed towards concurrent and reactive programming which focuses on functional modularity which is provided by functional languages like Scala.

Concept of functional programming is completely a new era for the hard core Java Programmers and lambda expressions are bridging OOP and FP by adding functional language capabilities to Java. You will find this concept roaming around anonymous classes and functional programming.
