The lambda expression is made of two parts the one on the left of the arrow symbol (->) listing its parameters and the one on the right containing its body. In this case the compiler automatically figures out that the lambda expression has the same signature of the only non implemented me...
startis a local variable, and we are trying to modify it inside of a lambda expression. The basic reason this won’t compile is that the lambda iscapturing the value ofstart, meaning making a copy of it.Forcing the variable to be final avoids giving the impression that incrementingstartins...
We've seen how to use generics and why they are important. Now let's look at the use case for generics with respect to a new construct in Java SE 8, lambda expressions. Lambda expressions represent an anonymous function that implements the single abstract method of a functional interface. T...
It is quite likely that you might see the code example we started with in this section coded using an if-else construct instead of an switch statement. Are there any benefits to converting an if-else statement to a switch expression. Let’s find out in the next section. 2.2. If feasible...

The debate over checked vs. unchecked exceptions goes way, way back. Some say it’s one of the best features Java included. Others say it was one of their biggest mistakes[1]. It looks like the debate is over. In this post I will try to include the links to articles and books which...
Cannot convert lambda expression to type 'System.Threading.Tasks.Task' Cannot convert null to 'int' because it is a value type--need help Cannot convert string[] to string in foreach loop Cannot convert type 'System.Collections.Generic.List<Microsoft.Azure.Cosmos.Table.ITableEntity>' to 'Syst...
Anonymous functions, also known as lambda expressions, can be defined in Haskell like this:\x -> x * xThis expression denotes an anonymous function that takes a single argument x and returns the square of that argument. The backslash is read as λ (the greek letter lambda)....
