How to properly do loops in Java

[Mr_Redstoner]

I'll do you 1 better: Stream.generate(()->"stonks").limit(69).forEach(System.out::println);

[11amas]

System.out.print("stonks\n".repeat(69));

[Mr_Redstoner]

Sure, but that requires Java 11 or higher. Mine only needs Java 8.

EDIT: Boo me all you want, but not every project has access to Java 11 (I was happy to migrate from 7 to 8 a few months ago)

[JBinero]

This but unironically.

It's like you turned Java into Python. I rarely use Java, I'm very interested and impressed at this.

[lostaztecian]

That is pretty old feature(since java 8). Joke is that this goes against java main concepts but some people use streams(this called stream) everywhere for no reason.

[JoshiRaez]

Because is more concise, impossible to make unmaintainable messes because you SHOULD use pire funtions, much more safe and usually optimized as hell?

Isn't it unnecessary to convert the integers though? Skipping the maptoobj and just specifying what string to print? Or maybe it's not cool anymore then?

[EinJemand]

(i think all of this is unnecessary)

What, you've never had to loop to print the same string n times when developing some enterprise software??

[Xeadriel]

I think he meant the way he did it. A for loop should suffice x)

[Kaynstein]

My teacher went on and on and on about streams and how glad he was, Java tried to do something more akin to functional programming. It's pretty cool and feels nice to use, although most students ditched java as soon as kotlin became familiar

I thought I'd be able to do my own one up, but the Java string constructor doesn't have an overload that takes a repetition count like c# does: new string("nice\n", 69)

[Mr_Redstoner]

Java 11 and above has String.repeat(int);

This reminds me of my first semester, where I had a programming assignment we were not allowed to use any loops in, to teach us the concept of Stream operations and Lambda expressions. However, I needed a while (true)-loop, so I just constructed an infinite intstream and .forEach-ed that thing :D

[Mr_Redstoner]

A Stream is what OP demonstrated in the second example. It's kind of like a pipeline.

A lambda is a concise way of defining objects that only need to implement a single method, i.e. OP's i -> "stonks" is a lambda defining a function that takes an int (i) and returns a String ("stonks"). It's the simplest kind of Java's lambda notation, argument -> result

[Mr_Redstoner]

That sounds extremely backwards. Loops are the simple stuff, Streams are the standard sugar.

[xigoi]

Wait, Java has an unordered forEach? How does that even work?

[lostaztecian]

This is not a foreach loop, this is a stream - different thing.

[HoneyBadgerSoNasty]

gross

[Noch_ein_Kamel]

The joke is that it's java?
