You want to create an object, so what you're looking for falls under the umbrella of creational design patterns. I'm not sure if there's a perfect fit for your needs, but the Factory pattern matches some of your needs.

In a typical Factory pattern use case, you would supply a type (as a String or enumeration) to a method, and receive a matching object. Your logic would be a little more complex in that there will be several inputs and some branching logic to locate the correct type. For example, you can't just use a String "shirt" to get your object since the color is built into the types (you have RedShirt, BlueShirt, etc...).

As a final note, I'd consider asking yourself why RedShirt and BlueShirt have to be of different types. Rather than using a design pattern to get around the issue, I'd reconsider the original design. For example, you could use an Apparel extends Product class containing a color and type member, such that you can query that information regardless of the type of Apparel. Of course, use your best judgement depending on your situation.

1. In the code you showed, dict_factory is not being called. conn.row_factory = dict_factory simply assigns that function to the attribute row_factory. That means you just told your database connection in which way to treat rows (as dictionaries).
2. enumerate augments the "normal" iteration by the index of the element (it returns tuples (index, element)). If you did for col in cursor.description: then col simply holds the name of each column. Doing for idx, col in enumerate(cursor.description): instead provides tuples where the first element is the iteration index (starting at 0), i.e. (0, col0), (1, col1), .... Now the function dict_factory converts a row to a dict. It does so by iterating over the various columns and adding key-value pairs col_name: row_value_for_that_column to the dictionary.

The linux command rename is super helpful here. It can use regex to perform the renaming.

This can probably rewritten a bit, but it appears do to the job here:

I think there is really no easy solution, but I'm pretty sure it is possible to implement conversion in quite an elegant manner with OOP.

Essentially, you're dealing with ASTs in both cases. And the their structures are not so different at all. So if you'd manage to implement conversion routine for each of the possible node types, you should be able to convert the whole AST.

First of all, I'd start by implementing a good Java model for your JSON structure. Classes like AndExpression, ComparisonExpression, LikeExpression, OrExpression etc. For inspiration, check the generated classes of the Filter schema. Good modelling is essential here.

Use poliformic deserialization so that you get the proper object structure after parsing Jackson. Now you "only" need to convert this structure into your JAXB structure.

The simplest would be to add conversion methods to your JSON model classes directly. I'd make them all implement an interface with a method like:

At the very end of your PlayGame function, what happens is at arr[0][0], if it is 1, it says Redshirts win, otherwise Stormtroopers win, there is no chance for your code to check other grids. You should just move the Stormtrooper winning message outside of the nested for loop.

Your requirement kind of matches with position:sticky. I hope this helps for you

Your stack only takes ints. You need it to take Objects if you want to store anything at all. Java doesn't let you manipulate pointers, so you can't just use int like in C/C++. You could also use generics, e.g. public class stackx, which would give you something like stackx newStack = new stackx<>(5);.

In your code just add e.preventDefault():
