Loading an image in from a file

Question

Hi,
I am trying to load an image in from a file, I have found an example using the following code:
import java.awt.Image;
import java.awt.Toolkit;
import java.io.BufferedInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
public final class MainClass {
  private MainClass() {
  public static Image getImage(Class relativeClass, String filename) {
    Image returnValue = null;
    InputStream is = relativeClass.getResourceAsStream(filename);
    if (is != null) {
      BufferedInputStream bis = new BufferedInputStream(is);
      ByteArrayOutputStream baos = new ByteArrayOutputStream();
      try {
        int ch;
        while ((ch = bis.read()) != -1) {
          baos.write(ch);
        returnValue = Toolkit.getDefaultToolkit().createImage(
            baos.toByteArray());
      } catch (IOException exception) {
        System.err.println("Error loading: " + filename);
    return returnValue;
}Is this a good way of doing it? I want to load a series of images in from files, so I can later do a comparison against them. I am just wondering how to go about the whole process?
Many thanks, Ron

Answer 1

Can you store multiple images in memory and be able
to reference them all individually, or is it better
to store them in a construct, such as an array and
then loop through that when attempting to match?I'm sorry but I don't understand the question. And does it
have anything to do with images per se? Can it be generalized
without losing its meaning:
Can you store multiple objects in memory and be able
to reference them all individually, or is it better
to store them in a construct, such as an array and
then loop through that when attempting to match?It seems to me that multiple objects should be stored in
an appropriate collection, if that is what is required.
Perhaps you need to say more about what you are trying to
do, what your goal is, to make your question meaningful.
