Question

Write a program which will Ask the user a series of questions using the Scanner object Based on the input, draw a grid of star figures on the DrawingPanel You program should ask your user: . What R, G & B values to create a color to draw the figure? How many stars across should the fgure be? How many stars tall should the figure be? Note that your program does not need to error check the users responses Your program can assume the user is inputting the correct data format Based on this input your program should: Set the color of the graphics object, g, with a new color created by the R G B values Draw a grid of star figures (explained in starter code) The DrawingPanel should be the exact size needed to draw the grid Each star figure is 50 pixels wide and 50 pixels tall For example, if the user specifies 3x3, the panel should be 150px by 150px . You may find that your panel has a minimum width of 100px - don't worry about this Example User Input #1: ·Color: R = 70, G = 70, B = 70 10 stars across 2 stars tall Output: Drawing Panel File View Help x-152, y-1),r-255 g-255 b-255 Example User Input #2: ·Color: R = 0, G = 255, B = 100 8 stars across 8 stars tall Output: Drawing Panel File View Help x= 128, y= 12), r-255 g-255 b-255 Example User Input #3: Color: R 0, G O, B 150 . 4 stars across . 5 stars tall Output: Lej Dra...- File View Help x=51, y=0), r=255 g=255 b-255 Update, Replace or Add to This Code to get started *Before you can run the code below, you will have to save DrawingPanel.java in the same project folder: DrawingPanel.java import java.awt.Graphics; import java.awt.Color; import java.util.Scanner * Homework #2: * Update, replace, or add to this code * to form your solution public class HWO2_Starter_Code t public static DrawingPanel canvas; public static Graphics g; k A * This method creates a panel of size * 200x200. Your panel will have to vary * based on the user's input public static void main(Stringl] args) t canvas new DrawingPanel (200, 200); g canvas.getGraphics) star) * This method draws five lines to * create a star shape. The star is drawn * in the top left corner of the panel. public static void star) g. drawLine(0,15,50,15); g. drawLine(50,15,7, 50); g. drawLine(7, 50, 25, 0); g. drawLine(25, 0, 43, 50); g. drawLine(43, 50, 0, 15);

    public static void main(String[] args)
    {
        Scanner sc=new Scanner(System.in);
        int R,G,B,s_across,s_tall;
        int x=0;int y=15;

        System.out.println("Enter RGB codes");
        R=sc.nextInt();
        G=sc.nextInt();
        B=sc.nextInt();
        System.out.println("How many stars across");
        s_across=sc.nextInt();
        System.out.println("How many stars tall");
        s_tall=sc.nextInt();

        canvas = new DrawingPanel(s_across*50,s_tall*50);
        g = canvas.getGraphics();
        g.setColor(new Color(R,G,B));
        for(int i=0;i<=s_across*50;i++)

                x=x+50;


            }
            y=y+50;
            x=0;

        }


    }
    public static void star(int x,int y)
    {
        g.drawLine(x,y,x+50,y);
        g.drawLine(x+50,y,x+7,y+35);

        g.drawLine(x+25,y-15,x+43,y+35);
        g.drawLine(x+43,y+35,x,y);

    }

// compile and run and remember it needs DrawingPanel.java to run//

//run this file while having this and DrawingPanel.java is one folder//

//Compiled ,executed and tested //
