== Mistake in example? ==
Current version:
<source lang="java">
class ProxyImage implements Image {
private String filename;
private Image image;
public ProxyImage(String filename) { this.filename = filename; }
public void displayImage() {
if (image == null) {
image = new RealImage(filename); // load only on demand
}
image.displayImage();
}
}
</source>
Can interfaces such as "Image" be used as types?
Would this (still) be correct?
<source lang="java">
class ProxyImage implements Image {
private String filename;
private RealImage image;
public ProxyImage(String filename) { this.filename = filename; }
public void displayImage() {
if (image == null) {
image = new RealImage(filename); // load only on demand
}
image.displayImage();
}
}
</source>
Notice the difference between <code>private Image image;</code> and <code>private RealImage image;</code>.
