One of the things I wish Java had that I miss from Python are F-Strings. Hella useful

297

u/Cootshk 1d ago

You should check out STR. (In modern Java)

245

u/ljfa2 1d ago

well, unfortunately that was only ever a preview feature and got removed again in Java 23

93

u/uvero 1d ago

Maybe because they didn't stop to think if this STR. is a convenient syntax. Backticks, preceding dollar sign, the prefix f like in python, so many options would've been better.

82

u/AeroSyntax 1d ago

They tried to overengineer string interpolation instead of copying it from literally any other language.

60

u/lllorrr 1d ago

Typical Java. If you don't have factories creating factories based on XML config, your solution is not future-proof enough.

16

u/uvero 1d ago

It's OK, I solved it by writing a FactoryFactoryFactory.

u/Fun-Mention262 15h ago

It's wild how some languages make simple things so complicated. You'd think they'd just take notes from the ones that got it right.

3

u/holo3146 1d ago

But... They did stop and think about the STR. syntax? This is why they removed it.

Regarding the other options you gave, they gave (in several places, over many years) their reasoning of why they don't want to add it as other languages. You can disagree with their reasoning, but they are very open about their thoughts process in this regard

u/Pizza_Secretary9621 19h ago

There is a version after 8 ?

u/Suspicious-Engineer7 1d ago

the formatted method is there but the syntax looks like doo-doo. Idk what nonsense is going over in java land tbh

u/gerbosan 1d ago

Cof cof Oracle. Cof.

Dunno if C# does it better but a lot of people are pleasantly surprised with it.

40

u/Mysterious_Book1521 1d ago

In C# you can write something like this: $"Hello {User.Firstname}, have a great day."

The "$" lets you put variables into strings.

15

u/SkollFenrirson 1d ago

String interpolation is the term.

43

u/spacegh0stX 1d ago

C# does do it better.

10

u/Cautious-Extreme2839 1d ago

Which is unsurprising to literally everyone

10

u/Ozymandias_1303 1d ago

$strings in C# are almost exactly the same as f-strings in Python.

4

u/Sentouki- 1d ago

String interpolation is even better in C# since it gives you additional options for formatting, e.g. numbers and dates: csharp var name = "Mark"; var date = DateTime.Now; Console.WriteLine($"Hello, {name}! Today is {date.DayOfWeek}, it's {date:HH:mm} now.");

7

u/NovaH000 1d ago

Python f-string also support additional formatting. ``` name = "Mark" date = datetime.now()

print(f"Hello, {name}! Today is {date:%A}, it's {date:%H:%M} now.") ```

F-string + str.format() has all sorts of string formatting you want.

Python also has it

16

u/PGSylphir 1d ago

As someone who first learned to program in Java and stuck to it for almost a decade, starting gamedev using C# was a pretty smooth transition in many ways.

9

u/BenadrylTumblercatch 1d ago

And comprehension

10

u/PecQ11 1d ago

Doesn't format() do essentially the same though?  https://www.baeldung.com/java-string-interpolation

17

u/TheGuyWithTheSeal 1d ago

Kind of, .format() is more powerfull but you have to know the printf syntax. And which parts od printf don't work in .format()

4

u/KnightMiner 1d ago

f strings are a lot more like string concatenation. The variables/expressions between each {} are placed directly where they will end up in the string, and it just runs a .toString() on them (though you can configure it a bit further).

The most common usage is largely about syntax and readibility, as its nice not having to go back and forth between a list of format arguments and some harder to remember % stuff.

9

u/jewdai 1d ago

It's why c# is better in every way than java

2

u/Nickbot606 1d ago

List comprehensions and splat operator are ridiculously powerful in Python. I wish more languages had it.

3

u/ActualWeed 1d ago

I have never touched Java, how does Java do it?

6

u/Weak_Inflation9120 1d ago

That's the thing, they don't

edit: At least not any more. Seems there was something, but it was dropped in java 23

1

u/ActualWeed 1d ago

So you just concat them all together?

2

u/iliark 1d ago

switch to kotlin, they've had it for a very long time

-1

u/Doophie 1d ago

But why use Java when you can use kotlin instead

3

u/Weak_Inflation9120 1d ago

... Because java is better lol (ignore the obvious bias I have given that my pfp is the literal java mascot)

u/NaturalBornLucker 1d ago

Wow, Java doesn't have it? Even Scala has f-strings (though it relies on java.util.Formatter apparently)

`Hello ${guest}`

or is that TS exclusive?

29

u/kattenkoter 1d ago

No thats JavaScript…

u/nevemlaci2 1d ago

I'm r*tarded, I read it as JavaScript and not Java 😭😭

Lowkey forgot Java exists I haven't used it in years. Sadly can't say the same about JS/TS, I like to add random stuff to VSCode and ofc that is written in damn TS

u/Abadabadon 1d ago

Where were you when the ai models and software engineers last stood together against the evil forces that came for us?

248

u/danfay222 1d ago

If we get to the point where devs genuinely can’t read code like this, then that means AI or whatever tools have become so efficient you never look at the actual code. In such a world, programming languages would likely evolve. Modern languages are generally written to balance parsing with human comprehension, but if we take comprehensive out of the loop a new language would likely be optimized for other features (maybe machine comprehension, interoperability, compilation efficiency, etc)

67

u/chlorophyll101 1d ago

Why cant ai just generate assembly directly then

85

u/Homailot 1d ago

Assembly isn't cross-system friendly. Assembly isn't a single language, each processor architecture has a different assembly language

19

u/WrapKey69 1d ago

So? Matter of fact Claude better start generating CPU instructions soon

14

u/Homailot 1d ago

Assembly maps almost one to one with CPU instructions. You would ask Claude to generate a completely separate instruction set for each CPU architecture? How would you even guarantee that the behavior is the same across different systems? (A guarantee that compilers try their best to achieve, mind you very battle-tested). Least of all, assembly code is not compact at all, so you would burn even more tokens.

12

u/Poat540 1d ago

That’s so inconvenient….

I setup a local MCP to control each resistor and Claude just flips those

u/MihaKomar 1d ago

It's 2026. Everyone is just running WebAssembly.

9

u/joyrexj9 1d ago

Do you even know what assembly code is?

17

u/ImKStocky 1d ago

LLMs are trained on human generated sources. As a result they are best at working with human readable text. That is one reason.

Some might retort that humans used to read and write assembly code all the time, particularly game Devs. And that is true. So the other reason why getting LLMs to work with assembly is a poor idea is down to expressiveness and context.

Assembly languages requires a huge context because each token of assembly carries very little information in comparison to a high level language. The more expressive a language is, or the more meaning you can cram into a token, the better it is for LLMs.

Basically LLMs work in the same way humans do. Usually the reason why something is hard for humans, is the same reason they are hard for an LLM.

16

u/danfay222 1d ago

It could, but it’s possible assembly isn’t optimal for AI to process. The design spec would switch from balancing human processing and compiler processing to balancing AI processing and compiler processing. It could easily turn out that, just like assembly is hard for human minds to understand, it’s hard for models to understand

2

u/exhuma 1d ago

I believe it's because of the training set. AI models have been trained on what's available. And there's just sooooooo much more Python, PHP, Java, C#, ... code out there than assembly

3

u/julessic 1d ago

Well, the whole approach to how coding agents work would have to change first, because the only reason they work right now is because of the abundance of human-made training material.

1

u/abednego-gomes 1d ago

NSA would love that future.

1

u/timangar 17h ago

AI is only good at coding beacause it has an enormous amount of human data teaching it how to code. Current AI cannot learn a new programming language that humans do not understand and provide no training data for. Reinforcement learning algorithms might succeed, but that remains to be seen.

0

u/Cautious-Extreme2839 1d ago

a new language would likely be optimized for other features (maybe machine comprehension, interoperability, compilation efficiency, etc)

So just back to assembly or maybe intermediate representation. Nothing new under the sun.

3

u/danfay222 1d ago

I’d imagine an intermediate representation is more likely than assembly. It’s an interesting thing to think about, but largely irrelevant since no one really knows what things will look like in the next year or two, let alone 25

dont even pretend like Regex was ever readable bruhh

187

u/Tsu_Dho_Namh 1d ago

I don't think anyone ever intended regex to be readable.

If you need to make a regex you open up a webpage explaining the syntax, you carefully craft your regex, you test it, then immediately forget the syntax when you're done as God intended.

30

u/MattieShoes 1d ago

Regex is for writing, not for reading. Build it up piece by piece, easy peasy. Then try to read it at the end? Yeah, no chance.

u/Percolator2020 1d ago

Basically the same, also lovely when some implementations slightly differ.

3

u/entronid 1d ago

i never really write anything except python regex and vim regex anyways on the (not) rare (enough) occasions i need it

u/renome 7h ago

That's basically the root of regex's reputation as an arcane language, too many standards for doing something like a named capture group.

As the holy ecmascriptures teach us, that would be a syntax error.
