1、前言：

要实现动画的流畅展示需要在能展示图片的基础上对图片进行关闭，再切换下一张图片，这要关闭窗口，与延时函数以及while函数的配合使用

---

2、图片的展示以及自动关闭：

图片的展示以及关闭代码如下：

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;public class Main {public static void main(String[] args) {// TODO Auto-generated method stubwater w = new water("C:\\Users\\86153\\Pictures\\Saved Pictures\\微信图片_20220211134809.jpg");try {Robot r = new Robot();r.delay(3000);} catch (AWTException e) {// TODO Auto-generated catch blocke.printStackTrace();}w.dispatchEvent(new WindowEvent(w, WindowEvent.WINDOW_CLOSING));//关闭窗口}}class water extends JFrame{//打印图片类water(String PATH){//图片大小设置this.setSize(1000, 1000);//手动关闭窗口程序自动结束this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//加载图片ImageIcon imageIcon = new ImageIcon(PATH);//创建的JLabel设置其图标为上方加载的图片JLabel label = new JLabel(imageIcon);//将label添加到窗口中this.getContentPane().add(label);//图片居中this.setLocationRelativeTo(null);//窗口显示this.setVisible(true);}
}

Java中使用frame.dispose()时，该行代码被标记了横线，可能是因为该方法被标记为过时方法（deprecated method）所以取而代之使用 w.dispatchEvent(new WindowEvent(w, WindowEvent.WINDOW_CLOSING));方法

3、动画的连续展示：

以上述图为例，理论上从0出发可以到达任意的其他三个点且有多种路径，若上述0，1，2，3分别代表一张图的话，配合随机数的生成理论上可以产生不同变换且流畅的动画

将上述图转成矩阵有路径的坐标分别为（0，1）、（1，3）、（1，2）、（2，3）、（2，0）、（3，0）
变换成01矩阵入下：
[
0,1,0,0
0,0,1,1
1,0,0,1
1,0,0,0
]

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.WindowEvent;
import java.util.Random;import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;public class Main {public static String path[] = {"C:\\Users\\86153\\Pictures\\Saved Pictures\\0.jpg","C:\\Users\\86153\\Pictures\\Saved Pictures\\1.jpg","C:\\Users\\86153\\Pictures\\Saved Pictures\\2.jpg","C:\\Users\\86153\\Pictures\\Saved Pictures\\3.jpg"};public static void main(String[] args) {int index = 0;//初始化变量while(true) {//死循环int next = Math.abs(new Random().nextInt()) % 4;while(a[index][next] != 1) next = Math.abs(new Random().nextInt()) % 4;// System.out.println(index + " " + next);Water w = new Water(path[next]);index = next;try {new Robot().delay(500);//w.dispatchEvent(new WindowEvent(w, WindowEvent.WINDOW_CLOSING));//关闭窗口} catch (Exception e) { }} }public static int a[][] = {{0, 1, 0, 0},{0, 0, 1, 1},{1, 0, 0, 1},{1, 0, 0, 0}};
}class Water extends JFrame{//打印图片类Water(String PATH){//图片大小设置this.setSize(2000, 2000);//手动关闭窗口程序自动结束this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//加载图片ImageIcon imageIcon = new ImageIcon(PATH);//创建的JLabel设置其图标为上方加载的图片JLabel label = new JLabel(imageIcon);//将label添加到窗口中this.getContentPane().add(label);//图片居中this.setLocationRelativeTo(null);//窗口显示this.setVisible(true);}
}

能够切换但不够丝滑

优化代码：

import java.awt.FlowLayout;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.Robot;
import java.util.Random;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;public class Main {public static String path[] = {"C:\\Users\\86153\\Pictures\\Saved Pictures\\0.jpg","C:\\Users\\86153\\Pictures\\Saved Pictures\\1.jpg","C:\\Users\\86153\\Pictures\\Saved Pictures\\2.jpg","C:\\Users\\86153\\Pictures\\Saved Pictures\\3.jpg"};public static void main(String[] args) {int index = 0;//初始化变量Water w = new Water();while(true) {//死循环int next = Math.abs(new Random().nextInt()) % 4;while(a[index][next] != 1) next = Math.abs(new Random().nextInt()) % 4;// System.out.println(index + " " + next);w.Wate(path[next]);index = next;} }public static int a[][] = {{0, 1, 0, 0},{0, 0, 1, 1},{1, 0, 0, 1},{1, 0, 0, 0}};
}class Water extends JFrame{//打印图片类public 	JLabel label = new JLabel();public void Wate(String PATH){ //图片框大小设置//	setSize(2000, 1000);// 设置JFrame为全屏GraphicsDevice graphicsDevice = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();graphicsDevice.setFullScreenWindow(this);//手动关闭窗口程序自动结束setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//加载图片ImageIcon imageIcon = new ImageIcon(PATH);//创建的JLabel设置其图标为上方加载的图片label.setIcon(imageIcon);//更改图标setLayout(new FlowLayout(FlowLayout.CENTER));//调图像在框内位置//将label添加到框中add(label);try {new Robot().delay(300);} catch (Exception e) { }//窗口显示setVisible(true);}
}

全屏、且切换丝滑

代码：

import java.awt.FlowLayout;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.Robot;
import java.util.List;
import java.util.Random;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import java.util.*;public class Main {public static String path[] = {"C:\\Users\\86153\\Pictures\\Saved Pictures\\0.jpg","C:\\Users\\86153\\Pictures\\Saved Pictures\\1.jpg","C:\\Users\\86153\\Pictures\\Saved Pictures\\2.jpg","C:\\Users\\86153\\Pictures\\Saved Pictures\\3.jpg"};public static List<ImageIcon> PATH = new ArrayList<ImageIcon>();public static void main(String[] args) {for(int i = 0; i < path.length; i ++) PATH.add(new ImageIcon(path[i]));int index = 0;//初始化变量Water w = new Water();while(true) {//死循环int next = Math.abs(new Random().nextInt()) % 4;while(a[index][next] != 1) next = Math.abs(new Random().nextInt()) % 4;// System.out.println(index + " " + next);w.Wate(PATH.get(next));index = next;} }public static int a[][] = {{0, 1, 0, 0},{0, 0, 1, 1},{1, 0, 0, 1},{1, 0, 0, 0}};
}class Water extends JFrame{//打印图片类public 	JLabel label = new JLabel();public void Wate(ImageIcon PATH){ //图片框大小设置//	setSize(2000, 1000);// 设置JFrame为全屏GraphicsDevice graphicsDevice = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();graphicsDevice.setFullScreenWindow(this);//手动关闭窗口程序自动结束setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//加载图片//ImageIcon imageIcon = new ImageIcon(PATH);//创建的JLabel设置其图标为上方加载的图片label.setIcon(PATH);//更改图标setLayout(new FlowLayout(FlowLayout.CENTER));//调图像在框内位置//将label添加到框中add(label);try {new Robot().delay(300);} catch (Exception e) { }//窗口显示setVisible(true);}
}

以空间换时间将图片解压提前放入List线性表中
