This discussion on the etymology of lambda functions is interesting, but the real question is how these mathematical concepts translate into Java. An example of a lambda function in a Java program. In Java, there are many, many places in which a piece of cod...
The biggest new feature of Java 8 is language level support forlambda expressions(Project Lambda). A lambda expression is like syntactic sugar for an anonymous class1with one method whose type is inferred. However, it will have enormous implications for simplifying development. 2.1Syntax The main ...
'Compile error: "Expression does not produce a value." Console.WriteLine is a Sub procedure (void, in C#), so it doesn’t return a value, which is why the compiler gives an error. To deal with this, Visual Basic 2010 introduces support for statement lambdas, which are lambdas that can...

Along with lambda expression, streams, and a couple of other changes, Java 8 has introduced a new concept called effectively final variable, which allows a non-final variable to be accessed inside an inner class or lambda expression. Earlier, you cannot access a non-final local variable inside...
