ImageIcon problem

Basiclly for now my goal is a drop down list which shows pictures depending on what is selected.

Code:

---

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class GUI extends JFrame{
        private JLabel ProfilePicture;
        private JComboBox HeroNames;
        private static String[] Heroes = {"Alchemist", "Ancient_Apparition", "Anti-Mage", "Axe", "Beastmaster",
                        "Bloodseeker", "Bounty_Hunter", "Broodmother", "Chen", "Clinkz", "Clockwerk", "Crystal_Maiden",
                        "Dark_Seer", "Dazzle", "Death_Prophet", "Doom_Bringer", "Dragon_Knight", "Drow_Ranger", "Earthshaker",
                        "Enchantress", "Enigma", "Faceless_Void", "Huskar", "Invoker", "Jakiro", "Juggernaut", "Kunkka",
                        "Leshrac", "Lich", "Lifestealer", "Lina", "Lion", "Mirana", "Morphling", "Nature's_Prophet", "Necrolyte",
                        "Night_Stalker", "Omniknight", "Outworld_Destroyer", "Puck", "Pudge", "Queen_Of_Pain", "Razor", "Riki",
                        "Sand_King", "Shadow_Fiend", "Shadow_Shaman", "Silencer", "Skeleton_King", "Slardar", "Sniper", "Spectre",
                        "Spirit_Breaker", "Storm_Spirit", "Sven", "Tidehunter", "Tiny", "Tinker", "Ursa", "Vengeful_Spirit",
                        "Venomancer", "Viper", "Warlock", "Weaver", "Windrunner", "Witch_Doctor", "Zeus"};
        private Icon[] pics;
        public GUI(){
        super("Dota 2 Helper");
        for(int i = 0; i < 67 ; i++){
                pics[i] = new ImageIcon(getClass().getResource(Heroes[i]+".png"));
        }
        setLayout(new FlowLayout());
        HeroNames = new JComboBox(Heroes);
        HeroNames.addItemListener(
                        new ItemListener(){
                                public void itemStateChanged(ItemEvent event){
                                        if(event.getStateChange()==ItemEvent.SELECTED)
                                                ProfilePicture.setIcon(pics[HeroNames.getSelectedIndex()]);
                                }
                        }
                        );
        add(HeroNames);
        ProfilePicture = new JLabel(pics[0]);
        add(ProfilePicture);
        }
}

Errors at:
pics[i] = new ImageIcon(getClass().getResource(Heroes[i]+".png"));
ProfilePicture = new JLabel(pics[0]);
add(ProfilePicture);

These might be related though

You mention "Errors at:..." but neglect to post the error message. That kind of is important information.

Exception in thread "main" java.lang.NullPointerException
at GUI.<init>(GUI.java:59)
at Main.main(Main.java:5)
main 5 is calling the class

You will need to instantiate the pics array before using it. i.e.,

Code:

---

private Icon[] pics = new Icon[someNumberGoesHere];

Thank you so much, good sir!

You're welcome!
