An extension method must be defined in a static class. An extension method must be defined as a static method. An extension method's first parameter must take the following form, where type is the name of the type to be extended: this type parameterName; An extension method may optionally define other parameters to follow the this parameter.
Here a whole switch expression can be used to return a value. There is also a new form of case label, case L-> where the right-hand-side is a single expression. This also prevents fall through and requires that cases are exhaustive. In Java SE 13 the yield statement is introduced, and in Java SE 14 switch expressions become a standard language ...
Whether it is a console or a graphical interface application, the program must have an entry point of some sort. The entry point of a C# application is the Main method. There can only be one declaration of this method, and it is a static method in a class. It usually returns void and is passed command-line arguments as an array of strings.

The next complete syntactic component (s-expression) can be commented out with #;. ABAP If the first character of a line, including indentation, is an asterisk ( * ) the whole line is considered as a comment, while a single double quote ( " ) begins an in-line comment which acts until the end of the line.

This illustrates an alternative method of specifying the default case, which can appear first, last, or anywhere in between. If no default is specified and no case matches the supplied value, a null value is returned. For each branch of a #switch, either side of an equals-sign "=" can be a simple value, an expression, or a template call.
