Java: trying to get random numbers out of class and read and changed in another [duplicate]

I am trying to make it so when you click on the buttons where it says "Power" + n or "power" + N it gives random value added to p. I try to make the variables static but it doesn't like it.

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;
import java.awt.*;
import javax.swing.*;

class DungeonRandomizer {
    
    public static class DungeonRand extends Canvas {
        public void paint(Graphics g) {
            int p = 0;
            int w = 5;
            int c = 0;
            Random rand = new Random();
            int n = rand.nextInt(25);
            int N = rand.nextInt(25);
            System.out.println("N" + N);
            System.out.println("n" + n);
            Color NeonBlue = new Color(64, 46, 255);
            Color Brown = new Color(64, 46, 32);
            g.setFont(g.getFont().deriveFont(20.0f));
            g.setColor(Brown);
            g.fillRect(0, 0, 1000, 100);
            g.setColor(NeonBlue);
            g.drawString("Your Power " + p, 10, 50);
            g.setColor(Brown);
            g.fillRoundRect(150, 400, 200, 200, 25, 25);
            g.fillRoundRect(650, 400, 200, 200, 25, 25);
            g.setColor(NeonBlue);
            g.drawString("Power" +   N, 215, 510);
            g.drawString("Power" + n, 715, 510);

I cant get the variables to be read and changed out side of the local class and I need that to happen. the variables i need to get are p n N. when i click on the buttons (the action listeners) they should take the random value displayed on screen and add to the var p and change on screen.
