That restriction is referred as " variable capture " which is described as; lambda expression capture values, not variables. The local variables that a lambda expression may use are known as " effectively final ". An effectively final variable is one whose value does not change after it is first assigned.

Lambda functions have been an addition that came with Java 8, and was the You can access a local variable only if it's effectively final, which means that it

I ett lambda-uttryck kan man använda attribut i den omgivande klassen variabler som är deklarerade final eller som ej ändras (”effectively. Now that Java is supporting lambda expressions, it's time to hone our skills Venkat helps his clients effectively apply and succeed with agile 1. Introduktion Java 8 ger oss lambdas, och genom association, begreppet effektivt slutliga variabler. Har du någonsin undrat varför lokala variabler som fångats Bakom det syntaktiska sockret hos lambdauttryck sveper Java fortfarande in dessa i has a limitation that the enclosing scope has to be final or effectively final.

只要该变量不被重新赋值就可以。. 一个非 final 的局部变量或方法参数，其值在初始化后就从未更改，那么该变量就是 effectively final 。.

lambdas expressions (anonymous inner class) cant modify local variables of surrounding method link here they must be final or in java 8 effectively final. Unlike instance variables, local variables do not get default values and if you want to use or return them you must initialize them first.

6 Aug 2015 This post is based on my workshop dedicated to the Java 8 Lambda variable used in a lambda expression must be final or effectively final. 29 Aug 2015 Java 8 introduced lambda expressions, which offer a simple syntax to create and use lambdas. Despite task 2 failing with an exception, the final result will be making Java development more interesting and more effi 3 Dec 2015 – The referred local variables should be either final or effectively final.

A non-final local variable or method parameter whose value is never changed after initialization is known as effectively final. It's very useful in the context of the lambda expression. Effectively Final in Java 8.
