Final tasks

For the you need to replace the program functionality exercise, do we count space and non letter character when calculating number of character? If we do, shouldn't "forty one" be odd? If we don't, shouldn't "j r" be even?

max and min has a validator issue. I was getting the correct output but I set max = Integer.MIN_VALUE and in their solution they just set both to the first element of the array. My solution worked but their validator didnt like it for some reason.

in the maximum and minimum numbers task, there's no reason not to determine the max and min in the same loop in which they are entered, yet the validator doesn't like it :/

shuffled just in time, im here so far: father mother son daughter cat dog program car father mother son daughter when i :

for (int i = 0; i<m; i++){
            list.remove(i);
        }

it removes every 2nd line, why?: mother daughter dog car father mother son daughter

for (int i = 0; i<m; i++){
            list.remove(0);
        }

"Be sure that you just display the array in reverse order. You don't need to reverse the order of the elements in the list." I don't understand this bit. How do you display an array (or arraylist) in reverse order without reversing the order of the elements? That sounds a bit like saying "paint the house red, but you don't need to paint the house red."

task0719 (Display numbers in reverse order) caveat: you will get failed if you use anything other than an ArrayList<Integer>, even though that requirement is not stated anywhere and this is not really an appropriate structure for the job.

Cat code won't compile exercise gives java.lang.NullPointerException even when I download the correct solution and it passes testing. I tried while(true){ String name = reader.readLine(); int age= Integer.parseInt(reader.readLine(); int weight=Integer.parseInt(reader.readLine(); int tailLength=Integer.parseInt(reader.readLine(); then pass these values to the constructor. But it keeps giving me NumberFormatException Don't know what is wrong with this but got an answer that I am trying to convert null to int.

Family census: Tips - Don't try like me to recreate their output ...... just display 4 objects with 3 parameter and 5 objects with 5 parameter

raise your hand if you've been victimized by predictive text... I know I have LOL

When it says the solution to the task is better than X% other students, what's the metric being used. Is it complexity or efficiency?
