How to put multiple objects in one jframe?

Basically I have this program that shows the maximum and minimum independent sets, but I want to draw/show 2 graphs instead of 1. Currently it only shows or highlights the maximum sets in one jframe, and i want to insert the minimum set.

What I have tried:

so this is the code block that creates the shape for the maximum sets. and I want to copy this block and revise it a little bit so that the minimum sets can be shown.

public class DC extends JComponent {
        public Shapes sp; 

        protected void paintComponent(Graphics g) {
            Graphics2D g2d = (Graphics2D) g;
            g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
            sp = new Shapes();
            int x = 59; 
            int y = 100; 
            for (int e = 0; e < allNodes.size(); e++) { 
                if (e < 5) {
                    sp = new Shapes();

                    if (waypus.equals("#")) {

                        boolean tf = false; //i will just make this true to make it minumum

                        for (int w = 0; w < waypusL.get(ux).size(); w++) {
                            if (sp.oDXof(waypusL.get(ux).get(w)) == e) {
                                tf = true; //i will just make this false to make it minimum
                            }
                        }   

                        if (tf == true) {
                            sp.drawCircle(g2d, x, y, "go");
                        } else {
                            sp.drawCircle(g2d, x, y, "stop");
                        }
                        x = x + 175;
                        continue;
                    }

                    sp.drawCircle(g2d, x, y, "stop");
                    x = x + 175;

                } else if (e >= 5) { 
                    if (e == 5) {
                        x = 59;
                        y = 375;
                    }
                    sp = new Shapes(); 
                    sp.drawCircle(g2d, x, y, ""); 
                    x = x + 175; 
                }

                if (e == allNodes.size() - 1) {
                    waypus = "b2wp";
                }
            }

            for (int k = 0; k < allNodes.size(); k++) { 
                
                sp.drawLine(g2d, greenCenter[k][0], greenCenter[k][1], allNodes.get(k));
                
                g2d.setColor(new Color(139, 0, 0, 255));
                
                g2d.drawString(allNodes.get(k).name, greenCenter[k][0] - 33, greenCenter[k][1] + 15);
            }
            g2d.setColor(new Color(0, 0, 0, 255));
            g2d.drawString("Number of Nodes = " + allNodes.size(), 59, 540);
            g2d.drawString("Number of Edges = " + (connections.size() / 2), 59, 560);
        }
    }

this is the created jframe this only shows one graph, which is the maximum set

public class DT {
    public void root() {
        int x = 893;
        int y = 643;
        DC dc = new DC();
        jframe.setSize(x, y);
        jframe.setTitle("Drawing of the Graph");
        jframe.add(dc);
        jframe.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); /
        jframe.setVisible(true);
        jframe.setResizable(false);
        jframe.setAlwaysOnTop(true);
        jframe.addKeyListener(new fromKB());
        jframe.setState(Frame.ICONIFIED);
        jframe.setState(Frame.NORMAL);
    }
}

So its basically adding 2 results in one jframe
