How do I read text from a file with an arbitrary extension in Java?

Also is there support for command-line arguments?

Kritixi Lithos

7:33 AM

Do you mean Java Java, or Processing Java?

Qwerp-Derp

@KritixiLithos Java Java, though I suspect that it's similar enough anyway

Kritixi Lithos

So you mean you want loadStrings("filename_without_extension") to load filename_without_extension.extension?

Qwerp-Derp

@KritixiLithos???

But I want to specify the file extension so that it doesn't get mixed up

Kritixi Lithos

I'd use scanner

Although Oracle suggests using BufferedReader (it much more verbose)

Qwerp-Derp

Yeah but doesn't Scanner read the input and output of files only?

Jan Dvorak

7:40 AM

Depends on what kind of file you're reading. Scanner is kinda good for user input - if the user cooperates - but it's far too high-level for binary files, and far too low-level for, say, JSON.

Ruby doesn't have that, and I never missed it

Kritixi Lithos

		try {
			Scanner blah = new Scanner(new File("lol.txt"));
			while(blah.hasNextLine()){
				System.out.println(blah.nextLine());
			}
		}catch(Exception e){
		}

Qwerp-Derp

Eww that indenting though

Kritixi Lithos

I had to paste it from vim

Jan Dvorak

looks like hard tabs. Hard, as in hard to read

DJMcMayhem

You see a bunch of circles with complex coloring, I see a complex polygon that is yellow inside and orange outside.

Qwerp-Derp

@HelkaHomba Dammit Helka all of your challenges create bandwagons somehow

Your challenges are too popular and good :P

Helka Homba

@JanDvorak that's one way to view it

but defining it programmatically as a complex polygon...I'd not be sure where to start

I forgot the name of the game where you click and ripples appear and when two collide there is sound

Uhh I need help with IntelliJ

So I have a package com.qwerpderp.pyramid, with a Main class on that folder

How do I access that Main class from the command line?

Jan Dvorak

com.qwerpderp.pyramid.Main ?

Qwerp-Derp

So just java com.qwerpderp.pyramid.Main <args>?

Where do I do that from, though?

This is probably specific to IntelliJ

Jan Dvorak

One does not simply run a class. You can set a class as a project's main class, in which case its main method will run when the project is ran.

My guess is that right-clicking the class lets you set it as the main class. If not, look in the project settings.

Qwerp-Derp

No but I need to run command line arguments

Like from bash

I built the project, there's an out folder

10:15 AM

I used to know how to do it. I think I've got it in a text file.

Then I threw up my arms and ran screaming away from Java.

flawr

@wizzwizz4 The earth is round. If you run for long enough you'll end up in Java again.

(in this case running includes swimming)

wizzwizz4

@flawr That's why I stopped and settled down here.

It's near enough to Java for me to overcome my fear of it.

Matthew Roh

We need a custom-criteria tag.

wizzwizz4

@MatthewRoh Why?

flawr

Why would we need one? code-challenge is not enough?

DLosc

10:18 AM

@flawr I was gonna say--Java is an island, you'll end up in the ocean pretty quickly.

wizzwizz4

The absence of a specific criteria tag is evidence of a custom criteria.

@DLosc I was running so quickly that I didn't sink.

Or notice. Anything.

flawr

@DLosc Unless you're good at Jesus-ing.

wizzwizz4

The water was thick because of the Java seeping into the water.

Matthew Roh

:\

flawr

(Or Moses-ing for that matter, if we're already making biblical references.)

@wizzwizz4 Another explanation would be that the water around Java is so slow, you're already gone by the time you'd get wet.

Matthew Roh

DLosc

Wait. My meta question is on Hot Meta Posts?

@DLosc That's not me! ~~The ankle area is the wrong shape, for one.~~

Qwerp-Derp

@MatthewRoh Why you have to roast Java :(

Jan Dvorak

10:37 AM

Because roasting PHP is too mainstream

Matthew Roh

Because Java is too Java-ish

Yes, I'm using 'Java' as an adjective here

wizzwizz4

@MatthewRoh No, you're not. You're using Java-ish as an adjective.

wizzwizz4

10:39 AM

@Qwerp-Derp Found it:

('-m', '--main', dest='mainclass', help='Main class to start')

Qwerp-Derp

???

But I have arguments in my main class

wizzwizz4

Use -m or --main, then type the class name.

Qwerp-Derp

So like this? java -m com.qwerpderp.pyramid.Main

wizzwizz4

Yes.

('-j', '--json', dest='json',action='store_true', help='Use the json file to setup parameters')

I'm not sure how this (^) one works, though.

Qwerp-Derp

That doesn't work :(

wizzwizz4

10:42 AM

Wait, the old text in this message is useless.

@Qwerp-Derp Gotcha. You just provide the extra arguments as extra arguments.

Qwerp-Derp

The error's not in the extra arguments - the error's in the actual -m tag itself

wizzwizz4

@Qwerp-Derp Really?

Qwerp-Derp

For some reason I'm getting Unrecognised option: -m

wizzwizz4

@Qwerp-Derp Try --main.

Qwerp-Derp

Same error

wizzwizz4

10:53 AM

Well, I'm stuck.

It's not in the text file at all.

Baktun

A baktun (properly b'ak'tun /ˈbɑːkˌtuːn/; Mayan pronunciation: [ɓakʼ ˈtun]) is 20 katun cycles of the ancient Maya Long Count Calendar. It contains 144,000 days, equal to 394.26 tropical years. The Classic period of Maya civilization occurred during the 8th and 9th baktuns of the current calendrical cycle. The current baktun started on 13.0.0.0.0 — December 21, 2012 using the GMT correlation. J. Eric S. Thompson pointed out that it is erroneous to say that a Long Count date of, for example, 9.15.10.0.0 is in the “9th baktun”, analogous to describing the year 209 AD as in the “2nd century AD”.
