Thread: I cant draw in java

Hellow i am a new in forum and java codding also.
I have to make an arraylist wich take circle and square .
The suser give tha point x,y and colour for the shape but additional cycle gets the radius and the square of the 2 sideσ.
and draw the cicles and sqares with the colour give user and the x,y in the end inside of every shape write the perimetr and area.

heare is my code

import java.awt.Graphics;
 
 
public class Circle extends Shape{
 
    private double radius;
 
 
    public Circle(double x,double y, double radius){
       setPosition(x,y);
       this.radius=radius;
    }
 
    public Circle(double radius){
    	setPosition(0, 0);
    	this.radius=radius;
    	}
 
 
    	public double area() {
    	return 2 * Math.PI * radius * radius;
    	}
    	public double perimeter(){
    	return 2*3.14*radius;
    	}
    	public String toString()
    	{ return super.toString() + ": Center " +
    	"with Radius = " + radius + " with area : " + this.area(); }
 
 
 
}

import java.awt.Graphics;
 
import javax.swing.JPanel;
 
 
public class Square extends Shape  {
 
	private double height, width;
 
	    public Square(double x,double y, double height,double width){
	    setPosition(x,y);
	       this.height=height;
	       this.width=width;
	    }
 
 
	    public Square(double height, double width)
	    {
	    super.setPosition(0,0);
	    this.height=height;
	    this.width=width;
	    }
	    public void setdimensions(double h, double w) {
	    height = h;
	    width = w;
	    }
	    public double area() {
	    return height * width;
 
	    }
	    public double perimeter()
	    {return 2*height+2*width;}
	    public String toString() {
	    return super.toString() + ": Rectangle(" + height + " x " + width + ")" + " with area : " + this.area();
	    }
 
 
 
	    }

If there are errors, please copy and paste the full text here.

One problem with the code is the class Shape. That is the name of a Java SE interface. You should NOT use Java SE names for your classes. It makes for confusion.

everything is working but
The problem is i can't take and draw the cirle and the squre from array list.

here is the code i cant make object shape beacause i abstract class..
i dont know how to make to work is the method init i have make.

public class Main extends JPanel{
 
	static ArrayList<Shape> shape=new ArrayList<Shape>();
 
	public void init()                                      //called by another class method  
    {  
        JFrame frame = new JFrame("schematics");  
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);  
 
        Shape myPanel = new Shape();   
        myPanel.setBackground(Color.WHITE);  
        frame.add( myPanel );  
        frame.setSize(1000, 540 );  
        frame.setVisible( true );  
        myPanel.setSize(1000, 500);  
        myPanel.setVisible(true);  
       }  
	@Override 
	public void paintComponent(Graphics g) {  
        super.paintComponent(g);  
        g.setColor(Color.BLACK);  
        g.translate(0,500);  
       for(int i = 0; i<shape.size(); i++){       
 
        g.fillOval(shape.get(i).getX(),shape.get(i).getX(), 50, 50);
