Question

Java

public class Rectangle extends Shape{
    Rectangle(Double w, Double h)
    {
        super(dim -> dim[0] > 0 && dim[1] > 0, dim -> dim[0] * 2 + dim[1] * 2 ,dim -> dim[0] * dim[1],new Double[]{w, h});
    }
    
    static void DrawRectangle(   )
    {
       final String asterisk = "*";
       for(int i = 0; i <= w; i++)
       {
           for(int j = 0; j <= h; j++)
           {
               System.out.print(asterisk);
           }
           System.out.println();
