    Default Best approach to load .gif pictures into an Array then selecting few of them and attach to a lable

    I wish to load several Gif pictures into an array and then later select some of these gifs and attach to a label. What is the best approach?


    ImageIcon orange = new ImageIcon ("orange.gif");
    ImageIcon apple = new ImageIcon ("apple.gif");
    ImageIcon banana = new ImageIcon ("banana.gif");

    Image[] images = new Image[3];

    How do a load into array and then from array to Label

    thanks

    Default Re: Loading Gifs into an array

    Hello Dele and welcome to the Java Programming Forums

    I haven't tested this code but to load these into the array you could try:

            JLabel label;
     
            ImageIcon orange = new ImageIcon ("orange.gif");
            ImageIcon apple = new ImageIcon ("apple.gif");
            ImageIcon banana = new ImageIcon ("banana.gif");
     
            ImageIcon[] images = new ImageIcon[3];
     
            images[0] = orange;
            images[1] = apple;
            images[2] = banana;
     
            label = new JLabel(images[2]);

    Thanks for your reply.

    This is the code I am actually working with. The compiler complains about the array structure. I don't know why as it is the same as in your example.

    Dele

    import javax.swing.*;
    import java.awt.event.*;
    import java.awt.*;
     
     
    public class PictureDemo extends JFrame
    {
     
    	// Create an ImageIcon Object
    	ImageIcon pic1 = new ImageIcon("background2.gif");
     
    	// Create a JLabel and display image
    	JLabel label1 = new JLabel(pic1);
    	JLabel label2 = new JLabel(pic1);
    	JLabel label3 = new JLabel(pic1);
     
    	JPanel pnl = new JPanel();
     
    	ImageIcon pic4 = new ImageIcon("7.gif");	
    	ImageIcon[] images = new ImageIcon[3];
     
    	images[0] = pic4;
     
    	// Constructor
    	public PictureDemo()
    	{
    		super("Picture Display");
    		setSize(400,200);
    		setDefaultCloseOperation(EXIT_ON_CLOSE);
    		pnl.add(label1);
    		pnl.add(label2);
    		pnl.add(label3);
    		add(pnl);
    		setVisible(true);
     
    	}
    	public static void main(String[] args) 
    	{
    		PictureDemo picdemo = new PictureDemo();
    	}
     
    }

    Default Re: Loading Gifs into an array

    The Array setup is correct but the problem is you cannot declare the Array values there.

    You could try this:

    import javax.swing.*;
    import java.awt.event.*;
    import java.awt.*;
     
     
    public class PictureDemo extends JFrame
    {
     
        // Create an ImageIcon Object
        ImageIcon pic1 = new ImageIcon("background2.gif");
     
        // Create a JLabel and display image
        JLabel label1 = new JLabel(pic1);
        JLabel label2 = new JLabel(pic1);
        JLabel label3 = new JLabel(pic1);
     
        JPanel pnl = new JPanel();
     
        public static ImageIcon pic4 = new ImageIcon("7.gif");
        public static ImageIcon[] images = new ImageIcon[3];
     
        // Constructor
        public PictureDemo()
        {
            super("Picture Display");
            setSize(400,200);
            setDefaultCloseOperation(EXIT_ON_CLOSE);
            pnl.add(label1);
            pnl.add(label2);
            pnl.add(label3);
            add(pnl);
            setVisible(true);
     
        }
        public static void main(String[] args) 
        {
            images[0] = pic4;
            PictureDemo picdemo = new PictureDemo();
        }
     
    }

    This compiles fine but obviousally pic4 isnt displayed yet in your code.
