title: Rendering a image in java
body: <p>Hello i am trying to add a texture to a game i have just started to create and i keep getting errors and i was just wondering if someone could help.
  The errors keep point to this .java file and the code is as follows.
      package com.mime.minefront.graphics;</p>
  
  <pre><code>import java.awt.image.BufferedImage;
  import javax.imageio.ImageIO;
  
  public class Texture {
  
  public static Render floor = loadBitmap("\textures.textures/floor.png");
  
  public static Render loadBitmap(String fileName) {
      try {
          BufferedImage image = ImageIO.read(Texture.class.getResource(fileName));
          int width = image.getWidth();
          int height = image.getHeight();
          Render result = new Render(width, height);
          image.getRGB(0, 0, width, height, result.pixels, 0, width);
          return result;
      } catch (Exception e) {
          System.out.println("CRASH!");
          throw new RuntimeException(e);
  
      }
  }
  
  }
