QUESTION
I don't want to use any building tools or IDE i want to know how this all works and if anyone has any source where i can learn how to use the compiler and stuff like this pleas link them i thought of using class path but there are so many folders and i have seen it been used only in jars files not in .java files or should i compile them all
...ANSWER
Answered 2021-May-17 at 07:14There's two very different things to do depending on what your goal is:
if your goal is just to use the library, then use the build system they use (in this case gradle) to build a jar file and use that. The build system exists precisely with this goal in mind and trying to avoid using it for this goal is like insisting on screwing in a screw without using a screwdriver.
if you want to learn how the library is supposed to be compiled, then learn the build system that they use and read its configurations files (in this case build.gradle) and interpret it accordingly.
As you see in both cases you'll have to get at least some familiarity with the build system, because sufficiently complex software is more than just a bunch of source files.
First of all almost all software will have some dependencies. The build system usually takes care of grabbing the appropriate dependencies. And the dependencies of dependencies (called transitive dependencies).
Second, some (but definitely not all) software will require some auxiliary steps for building, such as converting some DSL files into generated code (parsers/lexers are a common sample, but protobuf is another example).
Third, as Dave Newton suggested in the comments, some software further complicates matters by changing the actual compilation steps themselves in a way that's not easily reproduced using just the JDK command-line tools (specifically things like the Lombok Gradle Plugin).

The following data is present in my Color ActiveRecord model:
[{"thing" : "cup", "color": "red"}, {"thing" : "car", "color": "blue"}]

Answered 2021-Apr-09 at 20:10The thing doesn't change that much if you use ActiveRecord, and IMO it remains more readable if you leave your query as it's in SQL.

I have .csv file that has a list of grocery items that has their UPC code and the product name. I already wrote some code to put the product's code and its name into a map and they are working fine (code shown below). Without using a TreeMap or anything related directly to using the Map interface, how do I extract the key set of the map into a list and apply a sorting algorithm on it (like quick sort, for example) and have an output of those sorted keys with their assigned value? (I can write the sorting algorithm by myself so it's not a concern). The keys and values are unique.
I can change the method to use an array list instead of a map and directly apply the sorting algorithm on in. I also know there are various great ways to do this sorting revolving around using the Map interface, but this is just for the sake of practicing and I'm curious to know how do I implement something like that.

You can use tab stops instead of padding the data with spaces. For example, to set the tab stops at 50 pixels, 200 pixels, and then 250 pixels, and with the third column being right-justified you can do it like this:
