kandi X-RAY | extnd Summary
Extend is based off Jon Resig's Simple JavaScript Inhertitance blog post with the added support for multiple inheritance and AMD & CommonJS loaders. It is also lint-free and removes a superfluous check which breaks Closure Compiler. This inheritence system has been tested on large production apps for desktop and mobile. It is recommended you import extnd.js using a CommonJS or AMD loader. Otherwise Class will be added to window and you could have name collisions.

Answered 2020-Sep-05 at 12:50I'm not sure what exactly the problem is. Do you use lombok? Do you use field mapping?
If you use field mapping your fields should be public (otherwise nobody can access them). If you make them public it works for me. Here's the code as I think it should be:

Answered 2018-Dec-02 at 07:42I presume that this is some variant of the popular "Decaf" language, often used in introductory CS courses.
It's not really clear to me why CUP only reports two conflicts, since afaics there are four conflicts in your grammar. Perhaps the version you pasted is not the version which generated the error message you included in your question.
The conflicts reported in the error message are the result of your use of right-recursion for both the list of variable declarations and the list of statements which make up a statement block.
Conventional wisdom will tell you that right-recursion should be avoided whenever possible, because it uses an unbounded amount of parser stack. Left recursion, by contrast, uses a constant amount of parser stack. That's a good rule of thumb, but most of the time the choice between left- and right-recursion will be dictated by the syntax. So, for example, if you are writing a grammar for arithmetic expressions without using precedence declarations, you will use left recursion for left-associative operators (which is almost all of them) and right recursion for right-recursive operators (such as assignment operators in C, C++ and Java).
Item lists can usually be written either way, since they will generally be collapsed into a vector rather than staying as a binary tree, so the normal case will be left recursion:
