How would I create a java program to display an image?

For starters you can also take a peek at the Java 2D tutorial [1].

In order to display an image in a Java program, you will first need to import the java.awt.Image and javax.imageio.ImageIO packages. These packages contain the necessary classes and methods for handling images.
To load an image from a file in Java, you can use the ImageIO.read() method. This method takes in a File object as a parameter and returns an Image object that represents the loaded image.
To display an image on a Java GUI, you will need to use a JLabel component. Create a new JLabel object and pass in the Image object as a parameter. Then, add the JLabel to your GUI using the add() method.
To resize an image in Java, you can use the Image.getScaledInstance() method. This method takes in the desired width and height of the new image as parameters and returns a scaled version of the original image.
To handle errors when displaying an image in Java, you can use a try-catch block. Wrap your image loading code in the try block and use the catch block to handle any exceptions that may occur. You can also use the ImageIO.write() method to write any errors to a log file for troubleshooting.
