can someone help me with java loops?
int total=0;
for(int s=1; s<15; s++)
{
total=total+s;
} out.println(total);
for(int s=1; s<15; s++)
{
total=total+s;
} out.println(total);
out.println(total); that line isn't finished @Waterkid123012
yes someone told me that
what are you trying to do with it? @Waterkid123012
@daddycardona im learning how to do java
@daddycardona other people in the chat help me so im good
okay I was just wanting to know what was you trying to do with the println statement
i kind of made a mistake i should have puted the system.out.println
oh okay I was just wondering because people say that and they might need to put
console.log('stuf in here') or document.write('stuff in here')
he asking about
java NOT javascript
oooohhhhhh LOL my bag LOL
and he wrote java and I still interpret that as javascript where is my brain : )
@moigithub just smack me bro
:clap: pretend that is you smacking me lol

hello world need help
its giving me object object
hmm don't see anything wrong. Can you post the actual code here not a picture.

@gishy1 I'm not sure you can reassign lower[i] within the loop
may need to make a new variable outside the loop and assign it to first and second within the loop
not sure though... @sjames1958gm is the pro
@dhcodes It's just an array - replacing a string with another string.
ah
true, i said i'm not sure for a reason
lol
@dhcodes I entered this code into the challenge and it passes. Not sure what is happening with that [object object]
@dhcodes either way thanks bro

@dhcodes :)
well then
carry on
i'll be good at js someday
circa 2030. right around the time js moves on
@dhcodes "not sure" is a good state to maintain.
is it?
lol
I think so.
I am often not sure - the devtools console is my backup :)
well glad to hear i'm not the only one
@gishy1 A more advanced answer if you're interested:
// jshint esversion:6
function titleCase(str) {
return str
.split(' ')
.map(w => {
const arr = w.split('').map(l => l.toLowerCase());
return [arr[0].toUpperCase(), ...arr.slice(1)].join('');
})
.join(' ');
}
@kbaig na bro i need to first get the basics then I will work on more advanced answers
@kbaig No worries! Do try to understand map/filter/reduce as you progress. They make life a lot easier
@kbaig i will bro thanks !!

@kbaig Using
.replace you can make this a bit shorter :-)
Good morning, folks. I am trying to write a code that downloads files from a URL and throws it into a folder. Right now, it goes to the URL, downloads the file, but deletes and remakes the folder to put in another file and repeats until all files are done. I want it to have all the files in a single folder. I believe the placement of FileOutputStream in the For loop is the cause, but when I put it outside it causes Windows to through a .zip invalid error. Any ideas?
for (int i = 0; i < address.length; i++) {
URL url = new URL(address[i]);
BufferedInputStream bis = new BufferedInputStream(url.openStream());
FileOutputStream fis = new FileOutputStream(file);
System.out.println("Downloading from " + address[i]);
byte[] buffer = new byte[1024];
int count = 0;
while ((count = bis.read(buffer, 0, 1024)) != -1) {
fis.write(buffer, 0, count);
}
fis.close();
bis.close();
}
@alpox I was looking for a way to replace but couldn't find it. Forgot String.replace can take a substring instead of regex
@kbaig actually you need a regex in this case
@alpox why can't I just do
s.replace(s[0], s[0].toUpperCase())
@kbaig becazse that gives you only the first letter of the string in uppercase and not all word beginnings
@alpox of course, but i can separate the string into an array of words and map each word
And also, all occurrences of the character at the beginning of the string would be put in uppercase. Like every s would become S in the whole string
@alpox String.replace with a substring only affects the first occurrence
This would also happen if you split it in an array of words. Lets say you have the word "sister" which would become "SiSter"
Ah right @kbaig wasnt aware of that
You can do that then, but you would still have to split the array and put it together again
The challenge is possible with only a replace call though :D
@alpox yeah I'd prefer that over straight up regex but it is possible to just do regex
@alpox not that I work with a team of devs but if I did, I'd imagine it's better to do it without regex in this case so that others can quickly read what it's doing. Perhaps that can also just be achieved by giving the function a descriptive name in this case. I suppose you could argue either way
@kbaig may be the case if the regex was complicated. Its really simple enough that any dev should be able to read it
@alpox Besides garbage recent self-taught ones like myself :)
@kbaig
function titleCase(str) {
return str.toLowerCase().replace(/( |^)./g, m => m.toUpperCase());
}
@kbaig I believe you can read that too :D
@alpox honestly, I would have to look up the chars to figure out what it means
@alpox So this would be capture the character, so long as it is not a newline, if it is preceded by a space or it is the beginning of the string
and the
g flag means find all instead of just the first occurrence
But I thought it was only supposed to capture what is wrapped around the parentheses? It's capturing what is not in the paren here
@kbaig It captures just all whitespace or line begins together with a random character following
I just take the whole thing - the character together with the line begin or whitespace and upper-case it in-place
I see that now. But when there are paren, isn't it only the paren that's supposed to be captured?
morning fCC

@kbaig captured, yes. But MATCHED is always the whole, well, from the regex matched range. In the replacement function you get as first argument the whole match and the rest of the arguments would be the capture groups. I ignored them because i didnt need them. I only put a group there for giving the "or" a scope
Meaning the piping
@alpox gotcha thanks for the breakdown

Has anyone ever had problems adding SCSS to create-react-app? I followed the instructions in the CRA docs, but I basically get this error whenever I try to save a scss file.
=> changed: project\styles\sass\styles.scss
{
"status": 3,
"message": "File to read not found or unreadable: project/styles/sass/styles.scss",
"formatted": "Internal Error: File to read not found or unreadable: project/styles/sass/styles.scss\n"
}I found threads like this:
sass/node-sass#1894
michaelwayman/node-sass-chokidar#14
thanks but no thanks @DarrenfJ

@kbaig yep
@eunipa hmm. I was actually looking into this last night. Will get back to you if/when I have it working tonight
@kbaig I don't know if you're getting the same error as me, but I think mine is caused by my hard drive being slow at writing
@eunipa I did have that error in one of my project, not sure how to fix though
I also used the same setup for another project which I never had that error
@eunipa just did it and it seems to be working fine for me :/
@kbaig I have 2 projects using node-sass-chokidar and one worked flawlessly, the other one had that error
not sure of the cause though
not sure of the cause though
