Javagony!

It's Java!...but without any control flow statements except for try-catch, and no ways to loop except recursion!
Why does this exist???
If you want to try this out yourself, you can use the standard Java compiler and a regular IDE, just don't use the banned statements.

Is branchless programing allowed?

[@thekilla1234]

This will run forever: private static void runOne() { System.out.print(1); try { runOne(); } catch(StackOverflowError e) { runOne(); } } Eventually you will hit a StackOverflowError which is caught and replaced with a new call. Since you just had a stack overflow, the print() will cause a stack overflow but this time it is in the catch block and not the try block, which means the stack continues unwinding removing a runOne() from the stack. Eventually there will be enough stack space to run a full runOne() call, which will repeat forever.

[@SimonClarkstone]

AFAICT, that doesn't run forever, but does run for an extremely long time. It prints O(2^n) ones, where n is roughly how deep the stack can get.

[@branthebrave]

Good idea. Until your computer simply runs out of memory. I think there might be a way to increase the amount of memory to use up before stack overflow? Or, write a native method that manually deletes a all those method calls from the stack (won't work with backwards recursion then). Well, unless java has its own special call stack, which it probably does.

[@icif1234]

The truth machine doesn't crash if you implement thread-able objects. If you call start() on a thread it behaves on its own and you can dispose of the current thread, which means no overflow! class Recursive implements Runnable { @Override public void run() { System.out.println("1"); new Thread(new Recursive()).start(); try { Thread.currentThread().join(); } catch (InterruptedException e) { e.printStackTrace(); } } }

[@AntonioNoack]

I am late, yes, but why do you execute "Thread.currentThread().join();"? It does nothing. It joins thread x with thread x. It's like a nop instruction, just way more complicated xD.

[@koalakid3609]

Shut up nerd

[@elzearcontelly2651]

Because of the `join`, you're not freeing the calling thread, so it doesn't get discarded. You'll probably run out of RAM or your system will crash because there are too many threads quite fast. One solution would be to have the new thread join the previous one (currently it's doing the opposite)

[@nekoill]

If-else statements and switch cases are considered harmful and should not be used ever, anywhere. They're SLOW as all hell. Ternary operator, however, is fairly fine somehow, and it's a shame that you don't use it, because you should if possible instead of if-elses. Ternary operator, however, by definition only takes three arguments, so if you have a more complex case to deal with, you should check out a video here on KZbin called something to the tune of "Branchless programming" or something like that. Branching logic loads CPU with frequently useless computations the results of which it has to ultimately flush. Getting rid of if-elses is one of the reasons pure functional languages are so damn fast, but by far not the only one of course.

[@NonTwinBrothers]

Javagony: Surprisingly usable!

[@photophone5574]

You can also check if an integer is greater than a number through recursion: How to check if a number is negative or positive through incursion: Create two variables that are copies of the integer you want to check. Subtract 1 from the first copy and add 1 to the other. Use a try catch to check if one of the copies has reached zero. A < B A - B = C Therefore C < 0

If a is < than b, the answer is negative. If you sqrt a negative number, it gives a NaN (Int) converts NaN to 0 1/0 triggers exception Cool vids you got m8, keep it up!
