Why I'm getting error??

Question

public class main
{
public static void main(String[] args) {
Shape s;
s=new Circ(1);
s.area();
s=new Rect(2,2);
s.area();
System.out.println(s.area);
public abstract class shape
{
public abstract double area();
class circ extends shape
{
private double ;
public circ(double r)
{
this.r=r;
}
public double area()
{
return r*r*3.14;
}
}
public class rect extends shape
{
private double h,w;
public Rect(double h,w)
{
this.h=h;
this.w=w;
}
public double area()
{
return h*w;
}
}

}

}
}

Answer 1

You have the code format completely backwards. Here is a corrected version of your code step through it on the code playground page and see if you can find where you have been going wrong.

public class main
{
public static void main(String[] args) {

Shape circle = new Circ(1);
Shape rect = new Rect(2, 2);

System.out.println(circle.area());
System.out.println(rect.area());
}
}

public abstract class Shape {

public abstract double area();

}

public class Circ extends Shape {

private double r;

public Circ(double r) {
this.r=r;
}

public double area() {
return r*r*3.14;
}
}

public class Rect extends Shape {

private double h,w;

public Rect(double h, double w) {
this.h=h;
this.w=w;
}

public double area() {

return h*w;
}
}
