How to change a `Float` into a `float[]`

[shadow schooner]

I've got this bit of code. comissionInput = scnr.next(); comissionSchedule[i] = Float.parseFloat(comissionInput); but the 2nd line doesn't work because of missmatch types of float and float[] because comissionSchedule is a float[]. Does anyone know how to allow comissionInput to be put into comissionSchedule?

also its in a for loop where the counter = i

[river void]

comissionSchedule is a float[]
that makes it not an issue. you're doing [i] on it, so you need a float there
if comissionSchedule itself was a float, you'd have issues

also, you have no Float here. Float.parseFloat yields a float.

[shadow schooner]

But I'm getting an error on the comissionSchedule[i] = ... ?

It's Type mismatch: cannot convert from float to float[]

[river void]

that means comissionSchedule[i] is a float[], so comissionSchedule is a float[][]

[shadow schooner]

yes correct sorry

[river void]

(btw, the right spelling is "commission", if you aren't aware)

[shadow schooner]

lol thanks

yea i've spelled it like 3 different ways in my code so far so oops

[river void]

so what are you trying to achieve with turning a float into a float[]? just wrap it in a 1-element array? that doesn't seem too useful
an array holds multiple values, but here you have just one

[shadow schooner]

String commissionInput = null;
            
int numOfCommissionInputs = 0;
System.out.println("Please enter the number of inputs you will have for the employee's comission schedule: ");
numOfCommissionInputs = scnr.nextInt();
            
while (commissionInput != "q") {
                
    float[][] commissionSchedule; // 2d array declaration
    commissionSchedule = new float[numOfCommissionInputs/2][2]; // 2d array initialization
    for (int i = 0; i < commissionSchedule.length; i++) {
        System.out.println("Please enter the minimum number of units sold, and then the corresponding price per unit. ");
        commissionInput = scnr.next();
        commissionSchedule[i] = Float.parseFloat(commissionInput);
        for (int j = 0; j < commissionSchedule[i].length; j++) {
                  commissionInput = scnr.next();                commissionSchedule[i][j] = Float.parseFloat(commissionInput);
        }
    }

}

[river void]

that while doesn't work btw

(we can get to that later)

[shadow schooner]

So if commissionInput is "q" i want it to quit, and I want the user to input the values into the 2d array

lol

ok

[river void]

is commissionInput supposed to be the size of the array?

[shadow schooner]

commissionInput is supposed to be the values inside of the array

[river void]

oh yeah yeah misread

[shadow schooner]

sry ik the code is awful

[river void]

when, then you'd have to just get input twice for 1 inner array
there's no reason to get input in the outer loop if you have an inner, there's nothing you need

[shadow schooner]

wait thats so true

System.out.println("Please enter the minimum number of units sold, and then the corresponding price per unit. ");
                    for (int j = 0; j < commissionSchedule[i].length; j++) {
                        commissionInput = scnr.next();
                        commissionSchedule[i][0] = Float.parseFloat(commissionInput);
                        commissionInput = scnr.next();
                        commissionSchedule[i][j] = Float.parseFloat(commissionInput);

                    }

like that?

wait

my brain isnt braining

[river void]

why not just use nextFloat

or nextDouble

[shadow schooner]

because it has to be a string to check if it's "q"

[river void]

oh right

[shadow schooner]

bc if "q" it stops

[river void]

you want that to work in the middle of this thing?

[shadow schooner]

I don't even need the j loop right? if the first input is going to be [i][0] and 2nd is going to be [i][1]?

yea

[river void]

theoretically yeah

but if you want to be able to break from any point in the loop, you have to check to break, a while won't work

a for could work but it'd be ugly as hell

[shadow schooner]

is this why you said the while loop doesn't work?

at the beginning

[river void]

no, != doesn't work for strings

[shadow schooner]

equalsIgnoreCase

[river void]

so 2 reasons why it wouldn't work, the != is the one i noticed fist

[shadow schooner]

i always do that

ugh

[river void]

sure that would work for the comparison, but because of your logic flow, the while won't be able to check the input while the inner fors are running, so that issue still persists

[shadow schooner]

yea true

how would you do if it you wanted it to check everytime?

[river void]

just use if and break here, it'll end up being much cleaner

[shadow schooner]

true

ok thank you thats so smart

[river void]

right after every input, check if it's q, if it is, break accordingly

for funzies, here's how you'd do it with a while

Scanner input = new Scanner(System.in);
int commissionCount = input.nextInt();
double[][] commissions = new double[commisionCount][2];

String val;
int i = 0;
int j = 0;
while (i < numCommissions && j < 2 && !(val = input.next()).equalsIgnorecase("q")) {
  commissions[i++][j++] = Float.parseFloat(val);
  if (j >= 2) j = 0;
}

look at that spaghetti

[shadow schooner]

lmao that is very gross

last thing

and ill stop bothering u

numOfCommissionInputs = scnr.next();
            if (numOfCommissionInputs.equalsIgnoreCase("q")) {
                break;
            }
            numOfCommissionInputs = Integer.parseInt(numOfCommissionInputs);

Why can't I do that last line?

[river void]

you can't change the types of variables

parseInt takes a String and returns an int, so there's no way you can convert it and reassign it to itself

[shadow schooner]

So then how do I check if it's a "q", and then break if so, but if not, change it into an int?

[river void]

you need a separate variable

also if you're using nested loops to check for q only once, then a single break; won't work. you'll need break label;, return; or System.exit(0);

[shadow schooner]

bruh

thank you so much
