not a statement?

        return false;
    }
    public String toString()
    {
        return x +", "+y+", " = speed;
    }
}        // put your code here

it says those red lettered ones are not a statement.
what's wrong with those?

The way you are assiging is incorrect as what you are trying to do is evaluate whether xx==x; which is a like used for conditions.

For you to assign the value use only one "="
ex : xx=x;

However i doubt it would work as there are no class variables as xx I think what you are trying to do is something like below

public void setX(int x){this.x = x;}
public void setY(int y){this.y = y;}
