Guys I need help. This is the code I made for my project. This is only the main i have 6 other java classes but I need help on this part. I will post an image of the output. It does not show anything. I have no idea how to make it work. This is java swing. Thanks.

import java.awt.Dimension;

import java.awt.Graphics;

import java.awt.Rectangle;

public class Drawing extends javax.swing.JPanel{

private String shape;

private Dimension dimens;

private Rectangular rectangular;

private Oval oval;

String shapetoDraw1;

private Graphics g ;

@Override

public void paintComponent (Graphics g){

super.paint(g);

if (shapetoDraw1=="Rectangle"){

rectangular.draw(g);

}

else{

oval.draw(g);

}

}

public Dimension getPreferredSize (){

dimens.height=200;

dimens.width=200;

return dimens;

}

public void drawShape(String shapetoDraw, String shapeColor, String fillType){

Rectangle rect=new Rectangle();

rect.x=10;

rect.y=10;

rect.height=50;

rect.width=50;

shapetoDraw1=shapetoDraw;

if (shapetoDraw=="Rectangle"){

rectangular= new Rectangular(rect,shapeColor,fillType);

}

else{

oval= new Oval(rect,shapeColor,fillType);

}

repaint();

}

}

The required outcome is supposed to look like this:

I want to at least see something with my code but nothing is showing.
