# Arraylist

Anyone could you tell was wrong with this code ? The program you are given declares an even nums ArrayList. Write a program to take numbers as input and add them an ArrayList while the size of the ArrayList isn't equal to 3. Then calculate and output the average of all values in integers. Sample Input 5 2 4 Sample Output 3 https://code.sololearn.com/ca11a18A8a09

corrected code: https://code.sololearn.com/cG88G2x3RokB/?ref=app however, you don't really need the array creation to store user input values, as you work only with 3 values... so you could avoid it and just do a for loop to get 3 numbers from user wich you add together (or add them linearly without loop), then you only have to divide by 3 the sum ^^
