4,645 PointsI am stuck on the Constructors Challenge. Please help. I am unsure of what I am doing.
The error is on: public GoKart (String mColor); { Please help.
public class GoKart {
private String mColor = "red";
public GoKart (String mColor); {
this.mColor = mColor;
}
public GoKart gokart = new GoKart("red");
public String getColor() { return mColor; };
}

10,365 PointsHi Madison,
I have modified and commented your code ....
public class GoKart {
private String mColor = "red";
//this is perfect declared and initialized member variable mColor
public GoKart (String color) {
// no semicolon required
//the Name of the Parameter that expects the constructor shouldn´t be the same as the member variable
mColor = color;
// the mémber variable is equal to the Parameter passed to the constructor
}
//GoKart gokart = new GoKart("red");
// in this challenge you don´t Need to create a new object
//you dont need to write public bevor creating an object
public String getColor() {
return mColor;
}
}
I hope it helps and you can grab the logic. If not don´t hesitate to ask :)

private String mColor = "red";
public GoKart(String mColor) {
/* The name of the Parameter can actually be the same as the variable
as long as you use "this." and it's more efficient this way. */
this.mColor = mColor;
}
public String getColor() {
return mColor;
}
