Java遥控风扇作业
作业：类组合+GUI编程
期末了作业还有一大堆，，，还有两天要交这个东东，于是今天花时间写了一哈，真是头疼。一点都没有过端午的感觉，还有好几门课没预习啊我自闭了
作业什么的都搬到这个博客来好了🐷
作业要求：带面板的遥控风扇。功能：开/关，调风速，定时（，摇头 该功能暂不考虑）🐖
定时：可用Timer类实现。
作业步骤：1.提取所需类，并给出类关系图，并尝试实现部分代码；
2.学了第9章后，用可视化编程模拟风扇操作/运行。下图提供6副渐进变化的静态图，依次延时切换（切换速度由速度来控制）可实验动态效果。界面可参考下图：
小白白，写得不好😭😫😱
public class ElectricFan extends JFrame{
JTextField speed,timing;
String s;
int sp;
JPanel switchPanel,timingPanel,adjustPanel,statePanel,fanPanel,controlPanel;
JLabel v,t;
FanPanel left;
ControlPanel right;
ImageIcon[] imgs= {
new ImageIcon("C:\\图片1.png"),
new ImageIcon("C:\\图片2.png"),
new ImageIcon("C:\\图片3.png"),
new ImageIcon("C:\\图片4.png"),
new ImageIcon("C:\\图片5.png"),
new ImageIcon("C:\\图片6.png")
};
int index;
FanPic fp;
Timer timer;
boolean IsOn=false;
ActionListener fanmove=new FanMove();
// ActionListener speedListener=new SpeedListen();
ActionListener timeListener=new TimingListen();
public ElectricFan() {
super("遥控风扇");
init();
}
private void init() {
left=new FanPanel();
right=new ControlPanel();
fp=new FanPic();
this.add(left,BorderLayout.WEST);
this.add(right,BorderLayout.EAST);
this.add(fp,BorderLayout.CENTER);
pack();
this.setBounds(0,0,680,344);
this.setResizable(false);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
然后是风扇面板- -
class FanPanel extends JPanel {
public FanPanel(){
speed=new JTextField(11);
timing=new JTextField(11);
switchPanel=new JPanel();
switchPanel.setPreferredSize(new Dimension(180,63));
switchPanel.setBorder(new TitledBorder("开关"));
addButton(switchPanel,"开",new Switch());
addButton(switchPanel,"关",new Switch());
timingPanel=new JPanel();
timingPanel.setPreferredSize(new Dimension(180,63));
timingPanel.setBorder(new TitledBorder("定时"));
addButton(timingPanel,"+30",new TimeChange());
addButton(timingPanel,"-30",new TimeChange());
adjustPanel=new JPanel();
adjustPanel.setPreferredSize(new Dimension(180,63));
adjustPanel.setBorder(new TitledBorder("调速"));
addButton(adjustPanel,"1",new Speed());
addButton(adjustPanel,"2",new Speed());
addButton(adjustPanel,"3",new Speed());
statePanel=new JPanel(new FlowLayout(1,1,1));
statePanel.setPreferredSize(new Dimension(180,76));
statePanel.setBorder(new TitledBorder("状态"));
v=new JLabel("速度：");
statePanel.add(v);
statePanel.add(speed);
// speed.addActionListener(speedListener);
t=new JLabel("定时：");
statePanel.add(t,BorderLayout.SOUTH);
statePanel.add(timing);
timing.addActionListener(timeListener);
fanPanel=new JPanel(new FlowLayout());
fanPanel.setPreferredSize(new Dimension(200,310));
// fanPanel=new JPanel(new GridLayout(4,2,0,5));
fanPanel.setBorder(new TitledBorder("风扇面板"));
fanPanel.add(switchPanel,BorderLayout.NORTH);
fanPanel.add(timingPanel);
fanPanel.add(adjustPanel);
fanPanel.add(statePanel);
this.add(fanPanel);
}
}
本来全是用的GridLayout布局，辣么的整齐美观，然鹅状态面板是这个样子滴，,,,,
因为网格布局是每个组件都是大小相等的，我还能咋滴，还不是换个布局，，，同学们都用的Box，于是我用FlowLayout试一哈，还是勉强能看吧.，作为一个强迫症，硬是改了好几次数据。
然后是右边的遥控器面板- -
class ControlPanel extends JPanel{
public ControlPanel() {
switchPanel=new JPanel();
switchPanel.setPreferredSize(new Dimension(180,63));
switchPanel.setBorder(new TitledBorder("开关"));
addButton(switchPanel,"开",new Switch());
addButton(switchPanel,"关",new Switch());
timingPanel=new JPanel();
timingPanel.setPreferredSize(new Dimension(180,63));
timingPanel.setBorder(new TitledBorder("定时"));
addButton(timingPanel,"+30",null);
addButton(timingPanel,"-30",null);
adjustPanel=new JPanel();
adjustPanel.setPreferredSize(new Dimension(180,63));
adjustPanel.setBorder(new TitledBorder("调速"));
addButton(adjustPanel,"1",new Speed());
addButton(adjustPanel,"2",new Speed());
addButton(adjustPanel,"3",new Speed());
// controlPanel=new JPanel(new GridLayout(3,3,0,3));Grid的执着
controlPanel=new JPanel(new FlowLayout());
controlPanel.setPreferredSize(new Dimension(200,310));
controlPanel.setBorder(new TitledBorder("遥控器面板"));
controlPanel.add(switchPanel,BorderLayout.NORTH);
controlPanel.add(timingPanel);
controlPanel.add(adjustPanel);
this.add(controlPanel);
}
}
中间
放图片- -
class FanPic extends JPanel{
public void paint(Graphics g) {
super.paint(g); //重写需要先调用这个，所以不能删，嗯
g.drawImage(imgs[index%imgs.length].getImage(), 1, 46,this);
index++;
}
}
加按钮- -
private void addButton(JPanel panel,String name,ActionListener action) {
JButton button=new JButton(name);
panel.add(button);
button.addActionListener(action);
}
开关按钮功能实现- -
class Switch implements ActionListener {
public void actionPerformed(ActionEvent e) {
String str=e.getActionCommand();
if(str=="开") {
if(IsOn==true) {
}else if(IsOn==false) {
/*timer = new Timer(200,fanmove);
timer.start();*/
timer=new Timer();
timer.schedule(new FanTask(),0,200);
IsOn=true;
}
}else if(str=="关") {
timer.cancel();
IsOn=false;
}
}
}
Timer有两个，一个是在Swing里，一个是在util里。如果使用Swing里的Timer的话就
timer=new Timer(int,ActionListener);
timer.start();
但是后来我定时的时候就懵逼了，怎么都不对，约莫是我太菜的缘故。于是我后面都改用了util里面的Timer了。
timer=new Timer();
timer.schedule(new FanTask(),1000,200);延迟1秒，每隔200毫秒执行一次任务（好像是这样）。
如果是Swing里面的，就要- -
class FanMove implements ActionListener {
public void actionPerformed(ActionEvent e) {
fp.repaint();
}
}
另外一种的话，不需要监听器，但是要- -
class FanTask extends TimerTask{
public void run() {
fp.repaint();
IsOn=true;
}
}
class StopTask extends TimerTask{
public void run() {
timer.cancel();
IsOn=false;
}
}
123档调速按钮- -
class Speed implements ActionListener {
public void actionPerformed(ActionEvent e) {
String str=e.getActionCommand();
if(str=="1") {
if(IsOn==true) {
timer.cancel();
timer=new Timer();
timer.schedule(new FanTask(),0,200);
}else if(IsOn==false) {
timer=new Timer();
timer.schedule(new FanTask(),0,200);
}
}else if(str=="2"){
if(IsOn==true) {
timer.cancel();
timer=new Timer();
timer.schedule(new FanTask(),0,61);
}else if(IsOn==false) {
timer=new Timer();
timer.schedule(new FanTask(),0,60);
}
}else if(str=="3") {
if(IsOn==true) {
timer.cancel();
timer=new Timer();
timer.schedule(new FanTask(),0,6);
}else if(IsOn==false) {
timer=new Timer();
timer.schedule(new FanTask(),0,6);
}
}
}
}
定时文本框- -
class TimingListen implements ActionListener {
public void actionPerformed(ActionEvent e) {
String str=e.getActionCommand();
s=speed.getText().toString();
if(s!=null&&s.length()>0) {
sp=Integer.parseInt(s);
}else if(s==null) {
}
if(IsOn==true) {
timer.cancel();
timer=new Timer();
timer.schedule(new FanTask(),0,sp);
timer.schedule(new StopTask(),Integer.parseInt(str));
}else if(IsOn==false) {
timer=new Timer();
timer.schedule(new FanTask(),0,sp);
timer.schedule(new StopTask(),Integer.parseInt(str));
}
}
}
先输入速度，然后输入定时。
定时按钮- -
class TimeChange implements ActionListener{
public void actionPerformed(ActionEvent e) {
String str=e.getActionCommand();
if(str=="+30") {
}else if(str=="-30") {
}
}
}
这功能没写，就这样吧。头发要紧。🙃
最后- -
public static void main(String[] args) {
new ElectricFan().setVisible(true);
}
}
一天就这么过去了🙃😔😟😞😶😐🤨
啊我自闭了0.0
