import java.util.Scanner;

class Main {
  public static void main(String[] args) {
    Scanner in = new Scanner(System.in);

    String[] day = { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };

    for (int i = 0; i < day.length; i++) {
      System.out.println("How many pills do you take on " + day[i] + "?");

      int pills [] = in.nextInt();
      
      }
    for(int j = 0; j < day.length; j ++){
      System.out.print("On" + day[j] + "number of pillbox = " + pills[j]);
    }
  
    }

  }

this is my code to check how many pills was taken on certain day.

this is my error

I think nextInt returns an int, and I guess pills is an array of ints - but you can't just assign an int to the array, I guess you need to store it at a specific position?

turbid agate
#

how do i do that

rich cape
#

the second error is because you're creating the array inside the loop, so it only exists inside that loop

#

you need to create it before, and then you can use i to choose an index in that array

turbid agate
#

first loop or my 2nd loop

#

oh

#

do i change j to i?

Can you post the code again? Also have you tried debugging it?

yes

turbid agate
#

so i do int[] pills = new int[i];

#

before for loop?

austere cradle
#

yes

#

but if you know its size already (it will be one slot for each day) you can also specify its size, and then you can put data with pills[i]

#

I think if you dont set its size before, you cant just store values at indices, because the array will be empty and you would have to create these slots before putting data into them

turbid agate
#

ok my error says i is not defined

austere cradle
#

you can only use i inside the for loops

turbid agate
austere cradle
#

you dont need i when you define the array

turbid agate
#

but if i want to use i i would put it inside for loop?

#

it worked!!

Just to start, in line 5 the list of weekdays is not complete ...

#

for line 15 there is a loop missing to print it for each day, etc
