Constructors Quiz Question 1.. Need serious help.

I felt like I understood the video and still couldn't finish the question even after trying multiple, multiple times to get it correct.

Question: Add a public constructor to the GoKart.java class that allows the parameter color to be passed in. In the constructor store the argument color in the private color field.

What I got so far... (after multiple times of different code)

public class GoKart {
  private String mColor = "red";

  public GoKart(); {

  }

  public String getColor() {
    return mColor;

  }
}

Also I also got an error...

./GoKart.java:4: error: missing method body, or declare abstract public GoKart(); { ^ 1 error

Im pretty sure I got the "Add a public constructor to the GoKart.java class... (Yet if Im wrong I dont mind being corrected)

I'm stuck on two other things. The " that allows the parameter color to be passed in."

Sure that means inside the parameter...

and the "In the constructor store the argument color in the private color field."

Now I'm sure the "In the constructor" is inside the code block.

Seems like in the video, I was fine, but when it came to for the quiz, I'm confused. I just need help. Thanks.

You also need to create a variable to pass in such as

public GoKart(String color) {
}

You have to remove the semicolon in the constructor 

 public GoKart(); { // <---- here 

  }
