如何在Java中移动图片？

Question

I am beginner to Swing and I am writing some codes. I have added images on JLabel and JLabel on JFrame . I want to move that Image. Is it possible to move that image(fish). If yes, How can I do it?

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;

    public class Aquarium extends JFrame{

    private ImageIcon fish2image;
    private ImageIcon fish1image;
    private ImageIcon image;
    private JLabel imglabel;
    private JLabel fish1label;
    private JLabel fish2label;
    int numberFish = 12;

    public Aquarium(){
        initComponents();
        setTitle("The Aquarium");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);
        setResizable(false);
        setBounds(500,200,500,300); //left,top,width,height      

        add(fish1label);
        add(fish2label);
        add(imglabel);

    }
    private void initComponents(){

        image = new ImageIcon(getClass().getResource("../res/aquarium.gif"));
        fish1image = new ImageIcon(getClass().getResource("../res/smallFish.gif"));
        fish2image = new ImageIcon(getClass().getResource("../res/smallFish2.gif"));
        imglabel = new JLabel(image);
        fish1label = new JLabel(fish1image);
        fish2label = new JLabel(fish2image);
        fish1label.setBounds(100,100,250,200);
        fish2label.setBounds(50,25,200,200);
    }

    public static void main(String[] args) {
        new Aquarium();
    }
}

Answer 1

Repeat question. But you would shift the x, and y values (Based on keyBindings or KeyListener added on frame) and it will automatically repaint.

But since you want the fist to move automatically. You are going to need either a loop based on a swing timer, Thread.sleep(1000); <= Highly not recommended, or a Thread.

Then you would shift the x and y values as described above as a certain amount of seconds pass within the method that you choose
