Lambda's parameters types don't have to be fully specified and can be inferred from the interface it implements. Lambda's body can be written without a body block and a return statement if it is only an expression. Also, for those interfaces which only have a single parameter in the method, round brackets can be omitted. [8]
Lambda abstractions applied to a parameter have a dual interpretation as either a let expression defining a function, or as defining an anonymous function. Both interpretations are valid. These two predicates are needed for both definitions. lambda-free - An expression containing no lambda abstractions. {- [.
Added in Java 9, the underscore has become a keyword and cannot be used as a variable name anymore. [3] abstract A method with no definition must be declared as abstract and the class containing it must be declared as abstract. Abstract classes cannot be instantiated. Abstract methods must be implemented in the sub classes.
The name of a function (default), which may either be a symbol, or a sub-form beginning with the symbol lambda. If f is the name of a function, then the arguments a1, a2, ..., an are evaluated in left-to-right order, and the function is found and invoked with those values supplied as parameters.
And even if methods owned by the base class call the virtual method, they will instead be calling the derived method. Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding means having two methods with the same method name and parameters. Overloading is also referred to as ...
In computer programming, an anonymous function (function literal, expression or block) is a function definition that is not bound to an identifier.Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order function that needs to return a function.

Many programming languages require garbage collection, either as part of the language specification (e.g., RPL, Java, C#, D, [5] Go, and most scripting languages) or effectively for practical implementation (e.g., formal languages like lambda calculus). [6] These are said to be garbage-collected languages.
