Effectively Final in Java. When a lambda expression uses an assigned local variable from its enclosing space there is an important restriction.

But in the case of mutable object variables, a state could be changed inside lambda expressions. The body of a Java lambda expression does not define a new scope; the lambda expression scope is the same as the enclosing scope. A lambda expression may only use local variable whose value doesn't change. That restriction is referred as "variable capture". The local variables that a lambda expression may use are known as "effectively final". 2021-01-25 · Java Lambda Expressions is a new additional extension in Java 8.
