How do I get variables from objects of already existing programs? for example, if there's a world object in the program, and i already declared it, and that class has a height variable, how do it get it to print our that variable when i make the program run?

    public static void main(String[] args) {

        MainWindow mw = new MainWindow();

        World theWorld = mw.getWorld();

            ListorganismsInWorld = theWorld.getOrganisms();

import biogenesis.MainWindow;
import biogenesis.Organism;
import biogenesis.World;

	public static void main(String[] args) {

		MainWindow mw = new MainWindow();
		World theWorld = mw.getWorld();

			ListorganismsInWorld = theWorld.getOrganisms();
