Abstract Class Initialization

I have an abstract class:

abstract class Shape {

    public String color;
    public Shape() {
    }
     public void setColor(String c) {
        color = c;
    }
    public String getColor() {
        return color;
    }

    public double area() {
        return 0;
    }
}

Which provides non abstract methods and then i want to initialize it like:

     Shape object = new Shape();

so on initialization, it's still giving me an error, but why? If I provide one abstract method in the class, then it could be understandable that the class cannot be initialized. In this situation, why is it still giving an error? Any help would be appreciated
