Editing Comparison of C Sharp and Java (section)

===Lambdas and expression trees===
C# and Java feature a special type of in-line [[Closure (computer science)|closures]] called [[Anonymous function|lambdas]]. These are anonymous methods: they have a signature and a body, but no name. They are mainly used to specify local function-valued arguments in calls to other methods, a technique mainly associated with [[functional programming]].

C#, unlike Java, allows the use of lambda functions as a way to define special data structures called expression trees. Whether they are seen as an executable function or as a data structure depends on compiler [[type inference]] and what type of variable or parameter they are assigned or cast to. Lambdas and expression trees play key roles in [[Language Integrated Query]] (LINQ).
