"Editor's note" Although Java has won a lot of developers love, but compared to other modern programming languages, its syntax is indeed slightly lengthy. But with Java8, you can write code that is both readable and concise by using lambda expressions directly. The author Hussachai Puripunpinyo's software engineer, who analyzed the differences in performance and

This article does not introduce Lambda's past life, this is only a detailed understanding of the application of lambda expression. And the difference point with the inner class.Lambda expressionLambda expressions are new syntactic sugars introduced in the Java SE 8 release. Consider a function as a method parameter and
