how to correct the output
i am not getting proper output format

Just put a for loop for your arraylist like you put for an array to print elements. And instead of arr[i], for arraylist you have to use list.get(i) to access the ith element

still not getting right output

#5

for (int i=0;i<list.size()-1;i++) {
System.out.print(list.get(i)+" ,");
}

You just need to make these small changes. The loop will go till i<list.size() and you have print space after the comma, not before it

for (int i=0;i<list.size();i++) {
System.out.print(list.get(i)+", ");
}

still 2 wrong outputs

You have missed one case. See if length of both arrays is same and there is a carry over in the end, then you will have to check for it and add it. For example, consider the case where input is :

5
9 9 9 9 9
5
9 9 9 9 9

Then your code will give output : 9, 9, 9, 9, 8, END
but actual output should be : 1, 9, 9, 9, 9, 8, END

So, you need to put one if condition after all the while loops have finished :

if(a>0){
list.add(a);
}
