I know that to use a object prototype, you need to use the "new" tag. Is it wrong to know? But...
So instead of using the "new" tag outside of th...
I am trying to make a simple expression evaluator in Java using Jacc (a parser generator). I am done with the AST creation and now need to create an evaluator. For this I made a simple test to try to understand how visitors work. Here is my code

Can this be improved ? simply checking if a specific property is empty for all...

The following constellation:
Our applications pass date&time around (in the most horrible way possible).
We want to simplify this. Instead of a culture-specific string like '31.12.2019', we're now passing an ecma-timestamp (the number of milliseconds between the point in time in UTC and 1970-01...
Problem
I've been trying to create a variadic function that concatenates a group of strings together.
The function is to be sentinel-controlled (iterating through a sentinel argument stops the search for more arguments).
It's use case should be implicit and not require the user to add the se...
This emulates behavior of tab and shifttab with right and left.
I.e., switch focus to the next/previous select field with parent class .tab (which are not siblings in the DOM.)
It works, but any way to make it more elegant? Especially the if/then and the limit to range. I'm fairly new to javas...
