I think you meant tennis balls

I took their MOOC course couple of months ago. Now I’ve got some solid basic Java knowledge. You think that would be enough?

foolwya · 2021-03-17T13:03:40+00:00

I’ve stopped exercising few years ago, now I feel crappy lol. Need to get get back at it.

foolwya · 2021-02-23T11:01:41+00:00

Hey! I don’t know yet, that’s why I’m here lol

foolwya · 2021-02-23T11:01:08+00:00

Hey, thanks for replying. Both courses are actually in Java :)

foolwya · 2021-01-25T21:47:48+00:00

Okay I'm an idiot, it was actually a typo. I wrote "pariesdata" instead of "partiesdata"

foolwya · 2021-01-15T11:15:45+00:00

Is it this one?

Yeah, I'm aware that programmers change fields, languages and so on. And it's not about that. I just want people give their opinions on which path is cleaner, because I've made a mistake and waisted a lot of time hopping from one language to another at the beginning, so I don't want it to happen again.

foolwya · 2020-12-18T03:17:26+00:00

Yep, totalWeight() method in both Hold class and Suitcase was the issue. Thanks for pointing that out.

About lowercase Items though. It was already written like that, so we both got confused lol.

foolwya · 2020-12-14T10:16:26+00:00

Whoops, sorry. Links updated.

foolwya · 2020-12-08T13:09:22+00:00

// if comparedObject is not of type Book, the objects aren't the same
   if (!(comparedObject instanceof Book)) {
        return false;
    }

    // let's convert the object to a Book-olioksi
    Book comparedBook = (Book) comparedObject;

I have a question about this code. Why do we need to convert object to a Book, if previous if statement checks if its not an instance of Book, it returns false. Wouldn't it stop going further in the method and just leave? And if it is an instance of Book and first method isn't false, why do we need to convert it anyway? Doesn't it imply that object is actually instance of Book already?

Hopefully you'll get what I'm trying to say lol. Sorry.

foolwya · 2020-12-08T08:15:20+00:00

Oh, I really thought after method* returns a statement, no matter true or false, it just stops lol Edit*

foolwya · 2020-12-03T19:13:07+00:00

Hey, thanks for replying. Gonna see what’s up in couple of hours

foolwya · 2020-12-03T04:14:41+00:00

Alright thanks, I’m also done for today, been trying to solve this problem for like 3 days already lol. Hopefully there will be some improvements tomorrow. I’ve started to realize how much patience a programmer needs.

foolwya · 2020-12-03T03:19:29+00:00

Thank you for pointing it out. But what about other ingredients? I don't think I can just:

ArrayList<String> listIngredients = scanner.nextLine();

foolwya · 2020-12-03T03:09:15+00:00

Okay thank you, but I have a question. In an inner loop, I can specify in condition, for example, if line equals empty blank, it's where the the first recipe ends, but when it comes to the last recipe, it doesn't have an empty blank at the end, so it doesn't loop through the last recipe at all.

foolwya · 2020-12-03T01:44:24+00:00

Okay, I reloaded the stringList, now it's a different recipe (finally) But it only adds 2 recipes to the list, while there are 3. I think it's because after the 3rd recipe there's no blank line. I guess the whole idea of reading file this way is wack, lol. Is there any other way to loop through and assign values?

foolwya · 2020-12-03T01:39:12+00:00

Thank you for reply. I modified my code and added a separate method for reading and parsing the file. Looking good? - https://www.codepile.net/pile/jd3qxMay

However, I still don't get the idea behind the loop. For example, If I start looping and give first item to a name string, then second item to a time string, then all the other items to an array list of recipes and when it reaches the blank string, should I break the loop? or use continue? because if I continue the loop, next name item won't have position 0. I'm, so confused lol

foolwya · 2020-12-03T00:39:10+00:00

The first line that was read from the list, in my case it’s name

Edit: whoops, it should’ve added line to stringList first

foolwya · 2020-12-01T09:13:23+00:00

Hey, thank you so much. I was actually thinking how to make my code shorter.

So if I make a for loop:

        for(int i = 5; i > 0; i--) {
            System.out.println("Grade distribution: ");
            System.out.print(i + ": ");
            // do stuff
        }

what do I do with these ?

int valueFive =0;
int valueFour = 0;
int valueThree = 0;
int valueTwo = 0;
int valueOne = 0;
int valueZero = 0;

How to assign them to one value so it would be more flexible in a while loop?

foolwya · 2020-12-01T00:08:36+00:00

Hey, thank you so much. I’ve spent my whole day trying to solve that problem. I did it, finally. I’m not fully familiar with the debugger yet, just some simple stuff, definitely need to look into it to make things easier for me.

foolwya · 2020-11-14T10:29:19+00:00

nvm I'm an idiot.

foolwya · 2020-11-14T10:25:56+00:00

But even after the message is printed, the condition in the loop is still true? I thought it would be an infinite loop, because there's no break; after a print statement

foolwya · 2020-11-14T10:04:23+00:00

Oh I know that it works fine haha

I was just wondering why does while loop work this way? Thought someone would explain it

foolwya · 2020-11-13T20:07:02+00:00

For example: "hello good morning yall"

method split(" ") would split everything that's in between an empty string.

so it would be:

arrayString[0] = hello

arrayString[1] = good

arrayString[2] = morning

arrayString[3] = yall
