Java method

Java doesn’t have a preprocessor – so the simple answer is that you can’t. This sort of thing is normally handled in Java using Dependency Injection – which is both more powerful and more flexible.

A macro is an automated input sequence that imitates keystrokes or mouse actions . A macro is typically used to replace a repetitive series of keyboard and mouse actions and used often in spreadsheets and word processing applications like MS Excel and MS Word. The file extension of a macro is commonly .

You can use it inside a function , but it is not scoped to the function. So, in your example, the second definitions of a macro will be a redefinition and generate an error. You need to use #undef to clear them first.

Usually, with modern tools such functions are not longer necessary and with a good design and some abstraction and the interfaces that Java provides it is in general not necessary to have macros in Java . Java is designed, afaik, to make it as hard as possible to shoot yourself.

Macro definition are globally. It doesn’t care if you define it in the function or not . The preprocessor will replace the first occurrence of the macro and will go on.
