Hello, i have a little problem. I’m a newbie in java and i got problems with a list. I’ve created a class named Alibi with in the constructor:

```

public Alibi(String Str){

   this.icoAlibi = new ImageIcon(getClass().getResource(str));

this.imgAlibi = this.icoAlibi.getImage();

```

With all of them declared private Image and ImageIcon in the class Alibi.

And in my class Scene, the class linked to my main where I use swing drawImage. I declared 9 alibi, that i put in my list 

```

Alibi[] tabAlibi = {alibi1, alibi2,...}

```

Then in my scene constructor i put all my string like

```

this.alibi1 = new Alibi(« /images/alibi1.png ») 

```

And in my method paintComponent i got 

```

Public void paintComponent(Graphics g){

   Super.paintComponent(g);

   Graphics g2 = (Graphics2D) g;

   g2.drawImage(tabAlibi[0].getImg(), 0, 0, null);

```

And i have a white screen when i run it, i got in the console an error named « java.lang.NullPointerException ». And when i run it in debug mod, i saw that tabAlibi[0] is null. 

And for exemple when i run it with instead of using the tab and using directly:

```

g2.drawImage(this.Alibi1.getImage(),0,0,null)

```

 it do work why ? 

What do i need to do to fix it using the tab ? 

Thank for you help, i don’t know what to do...
