Help with tasks

where is the bug in my code ?

Just wanted to say thank you to all who commented on this lesson. I have to admit that I was very confused about what this wanted. I ended up downloading the correct solution and comparing against my version while factoring in the comments below. Because of all this, I was able to 'reverse engine

Those who used this way of solving the task, could you explain the logic/flow of this? I understand this is recursion, but switching the x & y and diving by the remainder, etc. I just can't follow it. Much appreciate it.

After completing the first two requirements, I just started trying different things. I started going through the description rather than the requirements and added food.onSelect(); food.onEat(); in the foodMethods method to see if the third requirement would pass, and the entire exercise passed. Wh

I've ran the program several times and it appears to pass all the task conditions but it will not verify. I eventually tried to use the model solution, but even that won't pass. Please help me figure out what's wrong.

Whats wrong with the return statement of my finger's containBones () method?

Why is the answer not 12 for each of the things in the array?

I just finished the task and review it, I found out that there is a Creation of Selectable interface in the main, how was that even possible? i think you can't create an object of an interface

Hi, I am being failed by the system when verifying the below code for requirement - The min method must return the minimum of the numbers a, b, and c. My result is 1 -3 3 5 I am unsure of where am I wrong in this. Arguments in the min function was pre-populated for the task. Thank you.

here, Orca class extends SeaCreture(abstract class with an abstract method) & implements CanSwim(has one method). The solution shows one method that is being overridden (@Override - CanSwim). It looks like it's the abstract method that is getting implemented, which it should. However, shouldn

not great. cant follow along and code. had a lot of momentum and the teaching style is not for me.

Classes in an Interface (I'm quite sure I haven't seen this before). What is the purpose or benefit of doing it this way vs. having it outside of the interface and implementing the interface?

need hint

I just finished the task, a little tip. Use this operator :)

... It says I am failing the last condition? What am I failing at that because the methods are called with the game.

What am I doing wrong?

Hi all, I'm trying to understand the logic on creating object and would appreciate it if someone can offer a clear explanation on the following example. My question is on line 24 & 25. From what I understand, this is using user-defined data type, BodyPart and assigning the return value of ro

this is from Java Core Level 3 Lesson 2, Beer part 2 Recovery. really want to know why this is allowed in Line 10 --> Drink beer = new AlcoholicBeer(); Drink is an interface, but here it's used as a Reference type. How is this possible? Someone did ask this question, but I could not und

Hi all, I'm trying to understand the solution given by CG. Can someone explain Line 37? why would Index ever be less than 0? Doesn't index starts at 0 and increase after that? Also, why is that needed? (I tried to run it commenting out L37, but it wouldn't). Thanks for the input.

how to change language to hindi?

Is there any problem with my codes?

Basically 2 questions: 1) I do not understand how we compare two byte[]. What does it return. I'm looking for a detailed description of the calculation 2) To display the byte[] as a binary String there are parts in the code that I can't find the meaning of. What exactly are we doing in the print()??

Hi all, I am curious about this portion of the code: public class Solution { public static void main(String[] args) { getDeliciousDrink().taste(); System.out.println(getWine().getCelebrationName()); System.out.println(getBubblyWine().getCelebrationName()); Sys

I am unsure on why the super.<> will not work, is it to do with not using an IDE instead of codegym? Am i meant to connect the separate chicken classes to the main? any help is appreciated.

Hi all, quick question. task 1408 Chicken Factory has the last condition which says, 9. All the classes you create must be in separate files. I don't actually know how to create a separate file that shows on different tabs. Right now, there are only 2 tabs - Solution & Continent. Can anyone

I tried to solve it like this: public Object getProxy(Class item, Class...items){ return (Object) Proxy.newProxyInstance(this.getClass().getClassLoader(), items, new ItemInvocationHandler(item)); } but I am getting the wrong output. Now I had a look at the "Right Solution" and I do

I solved it after looking up StackOverflow for examples around the modulus or remainder (%). I copied code, changed it to mine, and solved the puzzle, but now I still don't how this works EXACTLY. int sum = 0; while (number > 0) { sum = sum + number % 10;

The methods also are misty, wanna know how to call them with ease , "do they need some kind of creatvity or there is a one route of calling them?", when and also execute "print" them out and also how they are linked to the classes.

number = number | (number >> 1); number = number | (number >> 2); number = number | (number >> 4); number = number | (number >> 8); number = number | (number >> 16); return (number & ~(number >> 1));

This is one is a little bit fuzzy,this is how I wrote my for loop, for(String s = 4) {}....can i get light on this one?
