Java获取具有引用名称的文件

Question

I have a folder where images are stored for films with the same name as the film now when the user searches, the respective Image should show up for that film.

File ImageDisplay = new File("src/icons/random.png");  
BufferedImage originalImage = ImageIO.read(ImageDisplay);
ImageIcon icon = new ImageIcon(originalImage);

Now if i run this everything works fine and that image appear on every film.

But i want to do something like this:

File ImageDisplay = new File("src/icons/"+MOVIE_TITLE+".png");  
BufferedImage originalImage = ImageIO.read(ImageDisplay);
ImageIcon icon = new ImageIcon(originalImage);

Where MOVIE_TITLE is the film name from the database. But this gives me error which i cant seem to understand why. if i remove everything and just print it out by using:

System.out.println("src/icons/"+MOVIE_TITLE+".png");

The output in the console is correct for every movie where it prints out for example: The Godfather.png and so on. What am i missing?

Answer 1

I solved the problem. The error was that all films didn't have images and when it couldnt find that image for a corresponding film it gave an error.

I solved the problem by checking if the file exists first with this code:

 if(ImageDisplay.exists()) { 
             ImageDisplay = new File("src/icons/"+titleString+".png"); 
            } else {
                ImageDisplay = new File("src/icons/SsSs.png");
            }

And if the image doesn't exist replace it with another one.
