java - 他のオブジェクト内のオブジェクトへのアクセスと宣言

Question

私はJavaが初めてなので、私の単純さを許してください。この場合、GCompound の別のオブジェクト内のオブジェクトを呼び出すにはどうすればよいですか。以下のコードでは、「炎」を点滅させたいと考えています。しかし、run メソッドからは見えないようです。

import java.awt.Color;
import acm.graphics.*;
import acm.program.*;

public class BuildTower extends GraphicsProgram {

    GCompound Ekulobia;
    GCompound Dike_na_fia;
    GCompound Uli;
    GCompound Aniche;
    GCompound Achebe;
    GCompound Akuwanta;
    GCompound Ogbunike;
    GCompound Obinohia; 
    GCompound Aguata;

    private GCompound[] name = { Aguata, Ekulobia, Dike_na_fia, Uli, Aniche, Achebe, Akuwanta, Ogbunike, Obinohia } ;

    public void run() {
        setSize(800,300);
        GLabel towerName;   

        for(int i = 0; i <= 8; i++ ) {
            towerName = new GLabel (nameTower(i));
            towerName.setFont("Times-12");
            name[i] = new erectTower(towerName);
            add(name[i],50 + i * 80,100);
        }

        for(int i = 0; i <= 8; i++ ) {
            name[i].flame.setFilled(true);  /*cannot access flame in erecttower method*/
            pause (500);
            name[i].flame.setFilled(false);
            pause (700);
        }
    }

    private String nameTower(int n) {
        switch (n) {
            case 0: return ("Aguata");
            case 1: return ("Ekulobia");
            case 2: return ("Dike na fia");
            case 3: return ("Uli");
            case 4: return ("Aniche");
            case 5: return ("Achebe");
            case 6: return ("Akuwanta");
            case 7: return ("Ogbunike");
            case 8: return ("Obinohia");
            default: return null;
        }
    }
}
