I can always manage to pass the quizzes and the exercises in the classes. However the workspace is a total Catastrophe!

I go over things line by line and they look almost the same but for some reason and equal sign will be red not black, the the or lines don't work some reason. I am about to give up honestly.

GoKart.java
public class GoKart {
  private String mColor;

  public GoKart(String color) {
    mColor = color;
  }

  public String getColor() {
    return mColor;
  } 
}

Alright, judging by your code, you're stuck on step 1 of the challenge, am I right. So they want you to create a constant that is accessible from the class and not just an instance of it. So if you've listened carefully to Craig, you should know these two things:

  1. A variable is constant and cannot be change if it's preceded by the keyword "final". Meaning once it is initialized it will never be changed again. Note that it's accepted that constants should be with capital letters only.

  2. A variable is accessible from the class (ant not only the instance) when it is preceded by the keyword "static"

Therefore, when you add the modifier -> "public" and the type -> int, your code should be something like this:

public static final int MAX_ENERGY = 8;

No that not what I am talking these exercises, I can do with ease. It is inside the workshop launch workshop. I actually stopped doing the workshop long ago but it is frustrating not to be able to make them work. But thank you for the effort.

Can you share a snapshot of your workspace with us? Go to the three icons in the upper right of the workspace. Click on the first one that looks like a camera then click Take Snapshot and post the link here.
