if the compiler warned you when you just assumed an object wasn't null without proving it first (i.e. by manually checking) then you wouldn't need Option.

can you have nonnullable objects? seems pretty pointless if anything you know isn't Nothing or whatever it is in java could just be null after all

This exists. you tag things with @NonNull/@Nullable annotations and the ide uses that to figure out what can and can't be null

i'm using it in eclipse and it does make the language a bit less painful. but none of the libraries you'll want to use have nullability annotations, so it;s not exactly great yet

java style properties files are pretty straight forward

Properties are processed in terms of lines. There are two kinds of line, natural lines and logical lines. A natural line is defined as a line of characters that is terminated either by a set of line terminator characters (\n or \r or \r\n) or by the end of the stream. A natural line may be either a blank line, a comment line, or hold all or some of a key-element pair. A logical line holds all the data of a key-element pair, which may be spread out across several adjacent natural lines by escaping the line terminator sequence with a backslash character \. Note that a comment line cannot be extended in this manner; every natural line that is a comment must have its own comment indicator, as described below. Lines are read from input until the end of the stream is reached.

A natural line that contains only white space characters is considered blank and is ignored. A comment line has an ASCII '#' or '!' as its first non-white space character; comment lines are also ignored and do not encode key-element information. In addition to line terminators, this format considers the characters space (' ', '\u0020'), tab ('\t', '\u0009'), and form feed ('\f', '\u000C') to be white space.

If a logical line is spread across several natural lines, the backslash escaping the line terminator sequence, the line terminator sequence, and any white space at the start of the following line have no affect on the key or element values. The remainder of the discussion of key and element parsing (when loading) will assume all the characters constituting the key and element appear on a single natural line after line continuation characters have been removed. Note that it is not sufficient to only examine the character preceding a line terminator sequence to decide if the line terminator is escaped; there must be an odd number of contiguous backslashes for the line terminator to be escaped. Since the input is processed from left to right, a non-zero even number of 2n contiguous backslashes before a line terminator (or elsewhere) encodes n backslashes after escape processing.

The key contains all of the characters in the line starting with the first non-white space character and up to, but not including, the first unescaped '=', ':', or white space character other than a line terminator. All of these key termination characters may be included in the key by escaping them with a preceding backslash character; for example,

\:\=

would be the two-character key ":=". Line terminator characters can be included using \r and \n escape sequences. Any white space after the key is skipped; if the first non-white space character after the key is '=' or ':', then it is ignored and any white space characters after it are also skipped. All remaining characters on the line become part of the associated element string; if there are no remaining characters, the element is the empty string "". Once the raw character sequences constituting the key and element are identified, escape processing is performed as described above.

As an example, each of the following three lines specifies the key "Truth" and the associated element value "Beauty":

Truth = Beauty
Truth:Beauty
Truth :Beauty

As another example, the following three lines specify a single property:

fruits apple, banana, pear, \
cantaloupe, watermelon, \
kiwi, mango

The key is "fruits" and the associated element is:

"apple, banana, pear, cantaloupe, watermelon, kiwi, mango"

Note that a space appears before each \ so that a space will appear after each comma in the final result; the \, line terminator, and leading white space on the continuation line are merely discarded and are not replaced by one or more other characters.

As a third example, the line:

cheeses

specifies that the key is "cheeses" and the associated element is the empty string "".

Characters in keys and elements can be represented in escape sequences similar to those used for character and string literals (see sections 3.3 and 3.10.6 of The Java� Language Specification). The differences from the character escape sequences and Unicode escapes used for characters and strings are:

* Octal escapes are not recognized.
* The character sequence \b does not represent a backspace character.
* The method does not treat a backslash character, \, before a non-valid escape character as an error; the backslash is silently dropped. For example, in a Java string the sequence "\z" would cause a compile time error. In contrast, this method silently drops the backslash. Therefore, this method treats the two character sequence "\b" as equivalent to the single character 'b'.
* Escapes are not necessary for single and double quotes; however, by the rule above, single and double quote characters preceded by a backslash still yield single and double quote characters, respectively.
* Only a single 'u' character is allowed in a Uniocde (sic) escape sequence.

How so?

Also I don't see what problems xml is solving that protobuf hasn't also solved but better.

"Protocol Buffers are not designed to handle large messages. As a general rule of thumb, if you are dealing in messages larger than a megabyte each, it may be time to consider an alternate strategy."

"Protocol Buffers do not include any built-in support for large data sets."

"If you want to write multiple messages to a single file or stream, it is up to you to keep track of where one message ends and the next begins. The Protocol Buffer wire format is not self-delimiting, so protocol buffer parsers cannot determine where a message ends on their own."

in other words, protobufs are intended for sending short messages over the internet. they do that pretty well, but that's all they're good for. if you need to handle non-trivial quantities of data, you'd have to invent your own proprietary file format that maybe uses protobufs internally to store chunks of data (and then you still have to worry about whether those chunks might hit the size limit).

alternatively you could just get over your irrational fear of angle brackets and use xml.

Java libraries typically have excellent documentation. Of course, reading the source of a Java library to learn how it works is also a valid option, because Java programmers understand how to design their systems and don't try to show off how smart they are by using the cleverest code possible.

lol

tbh 99% of libraries in any language are underdocumented poo poo that dont quite do what you need, best plan is just to man up and take responsibility for writing your own code instead of relying on other people all the time

why is a factoryFactory a thing, i barely (lol jk not at all) grasp the need for factories

or really any programing paterns from a book

factories are necessary because sometimes you want to get an object but you want someone else to create it for you (maybe they're better placed to decide which implementation to use, or maybe they're doing caching or whatever). in java they can also be used to hack around the language restriction that prevents you treating a constructor as a value without wrapping it in an object first.

factory factories are necessary because the quality of java code is measured by volume.

the general purpose equivalent would be
code:

20 IF I < 0 THEN GOTO 40
30 GOTO 10
40
which is definitely less succinct, but has the benefit that the next programmer along to read your code doesn't have to be familiar with C idioms. it also doesn't "hide" an assignment where you wouldn't generally expect it.

Why do we even bother with structured programming?

yeah, porting fortran can be pretty bad.

the other week I was trying to get some code running on linux that was written like 20 years ago in a mixture of k&r c and fortran 77. by a mathematician. for unicos. without access to any of the cray manuals that might have told me what all the proprietary keywords were supposed to do.

its not a coincidence the most popular IDEs for c# and java (vs and eclipse) are also the two best IDEs. like I guess you could develop c# or java on a non-windows platform, but idk why they hell you would (esp c#).

The only reason I use java at all is because I have one program that still has some users stuck on windows, and using java means I don't have to develop it there (but can still be confident that it'll just work)

C# enums accept arbitrary ints for versioning reasons. Sum types force you to handle all cases at compile time, enums (in C# anyway) explicitly don't. As long as you have a default: in your case statement then you're fine.

exhaustiveness checking is the best thing about java enums. if i add a new member, the compiler will tell me what code needs to be updated to handle it. default clauses just hide the problem, like why are you using a statically typed language if you don't want static checks

nope

a core problem with c++ advocates is that they rarely understand what the gently caress c++ is.

hardly anyone understands that. look at anyone who says "c/c++" and you are looking at someone who only knows what one of those is

in that case i'm glad i only have one of those fake jobs where you can take some time out for personal development and still get paid the same

like when else are you going to read about it, on your personal free time? seriously?

we live in a world where someone can be considered a professional developer despite struggling with trivial concepts like pointers and recursion. at least regexps have some moderately subtle edge cases, and i guess the book maybe discusses implementation details as well?

most of the time iterative methods are superior and they are much more "will someone else be able to understand this in a year" friendly usually

idk there are cases where the recursive form is simpler and using iteration might be slightly more efficient but maybe not enough to be worthwhile. just do whichever fits your algorithm best really

Gazpacho posted:

because (1) the contract that other languages follow sucks whenever you have to fall back to legacy syntax just to get the index

good solutions:
1. provide two mapping functions, so you can provide the index when explicitly asked for it
2. do it like python's enumerate(), which explicitly maps a sequence to tuples that contain the index

bad solutions:
1. implicitly do something unexpected that can cause bizarre and non-obvious bugs

Gazpacho posted:

(2) parseInt isn't a collection mapping function, nobody said it would be, wtf would you expect it to fulfill any contract other than its own

yes, how unreasonable to expect different parts of the built in library to be composable like they are in non-poo poo languages

also lol if you think the main point of removing bad features is to make your lovely code run faster

ides are good for statically typed languages where they can give you instant feedback on errors and sensible auto completion and type information and stuff

if your working in a plang then they don't buy you much. just use sth like emacs with flycheck mode to employ whatever syntax checking tools are available

just use whatever language you like and is appropriate for the task at hand?

what if you're doing client side webdev? none of the choices are fit for any purpose and nobody who likes them should be trusted to write code
