Java effectively final variables

Java Java Programming Java 8. A final variable can be explicitly initialized only once. A reference variable declared final can never be reassigned to refer to a different object. However, the data within the object can be changed. So, the state of the object can be changed but not the reference. Java 1.1 and later versions allow you to mark a parameter as final; this prevents assignment to the variable.

In Java 8 with the addition of lambda expressions, a new concept effectively final variable has been added, which closely relates to lambda expressions. Prior to Java 8, inner classes had an important restriction that inner classes could only use variable from enclosing scope if it's final, that restriction hs been eased starting Java 8. Java 8 gives us lambdas, and by association, the notion of effectively final variables.

Yes. This is called variable capture.Instance and static variables may be used and changed without restriction in the body of a lambda. The use of local variables, however, is more restricted: capture of local variables is not allowed unless they are effectively final, a concept introduced in Java 8.Informally, a local variable is effectively final if its initial value is never changed

Effectively final variable is a variable that doesn't change its value (a constant). Such variables can be referenced in lambdas without the need to explicitly mark them as "final": 2018-02-02 · Final variable in Java. Java Java Programming Java 8.

Effectively Final in Java When a lambda expression uses an assigned local variable from its enclosing space there is an important restriction. However, starting in Java SE 8, a local class can access local variables and parameters of the enclosing block that are final or effectively final. A variable or 10 Feb 2016 Final vs Effectively Final A variable or parameter whose value never changes after it is initialized, is effectively final. A variable or parameter the performance benefit gained by declaring a method or class as final is usually zero.

Java 8 gives us lambdas, and by association, the notion of effectively final variables. Ever wondered why local variables captured in lambdas have to be final or effectively final? Well, the JLS gives us a bit of a hint when it says “The restriction to effectively final variables prohibits access to dynamically-changing local variables, whose capture would likely introduce concurrency

A variable which is not declared as final but whose value is never changed after initialization is effectively final. PS : It is worth mentioning that, anonymous classes can access only final local variables (in JAVA SE 7), while in Java SE 8 you can access effectively final variables also inside lambda as well as inner classes. Java 1.1 and later versions allow you to mark a parameter as final; this prevents assignment to the variable. It still allows you to modify the object the variable refers to.
