I'm getting the error : ./GoKart.java:4: error: invalid method declaration; return type required...

./GoKart.java:4: error: invalid method declaration; return type required public setColor(String color) { ^ 1 error

I don't see why I need to return something to set the Color of the Gokart.

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

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

  public String getColor() {
    return mColor;
  }
}

Hello Leen!

If you don't think you need to return anything then put the keyword 'void' where you would usually put what the function is going to return.

Void is a special keyword in Java which signifies that the function isn't going to return anything.

I hope this helped you out and good luck with your programming!

It was supposed to be a constructor so I just needed to put the keyword "GoKart". Thanks for learning me "void".
