Creating 2D game engine, image = null error [closed]

When ever I run this, I get the error

Exception in thread "main" java.lang.IllegalArgumentException: input == null!

I tried many different solutions including moving parts of the code around and removing other things which each broke some other part. I also tried .getResourceAsStream.

package gfx;

import java.awt.image.BufferedImage;
import java.io.IOException;

import javax.imageio.ImageIO;

public class SpriteSheet {

public String path;
public int width;
public int height;

public int[] pixels;


public SpriteSheet(String path) {
    BufferedImage image = null;


    try {
    image = ImageIO.read(SpriteSheet.class.getResource(path));
        } catch (IOException e) {
            e.printStackTrace();
        }


    if(image == null){
        return;
    }


    this.path = path;
    this.width = image.getWidth();
    this.height = image.getHeight();    

    pixels = image.getRGB(0, 0, width, height, null, 0, width);

    for(int i = 0; i <= pixels.length;i++){
        pixels[i] = (pixels[i] & 0xff)/64;
    }


    for(int i = 0;i < 8;i++) {
        System.out.println(pixels[i]);
    }


}       
}
