Question

每天固定时间在桌面右下角弹出提示信息窗口的java程序

桌面
看来我的问题有点歧义。。。我是需要java的代码来实现一个定时提醒的小工具。

Answer 1

一个关于定时提醒的弹窗例子，还不是很成熟，仅供参考
//主窗口界面设计
public class TestButtons {

JFrame frame = new JFrame("提醒");
JButton jButton = new JButton("开始运行"); //按钮
JCheckBox checkBox = new JCheckBox("早上提醒"); //复选按钮
JCheckBox checkBox1 = new JCheckBox("晚上提醒"); //复选按钮
JLabel label = new JLabel("Ready to run."); //静态文本
//构造函数
public TestButtons() {
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(new java.awt.FlowLayout());
//为按钮添加动作监听器
jButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent ae) {
//按钮事件处理程序
label.setText("Thread keep running.");
int i=Timetorun()*1000;
try {
Thread.sleep(i);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JFrame parent = new JFrame();
JOptionPane.showMessageDialog(parent, "该干啥了。");
}
});
//早上提醒 复选框处理程序
checkBox.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
JCheckBox cb = (JCheckBox) e.getSource();
label.setText("Selected Check Box is " + cb.isSelected());
}
});
//晚上提醒 复选框处理程序
checkBox1.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
JCheckBox cb = (JCheckBox) e.getSource();
label.setText("Selected Check Box is " + cb.isSelected());
}
});
//添加组件到容器
frame.getContentPane().add(jButton);
frame.getContentPane().add(checkBox);
frame.getContentPane().add(checkBox1);
frame.getContentPane().add(label);
frame.setSize(200, 250);
}
public void show() {
frame.show();
}

//主处理函数
public static void main(String[] args) {
TestButtons tb = new TestButtons();
tb.show();
}

//时间处理函数
public static int Timetorun(){

//获取系统当前时间
Calendar cal=Calendar.getInstance();
int nowhour=cal.get(Calendar.HOUR_OF_DAY);
int nowminite=cal.get(Calendar.MINUTE);
int nowweek=cal.get(Calendar.DAY_OF_WEEK);
System.out.println(nowhour+"");
System.out.println(nowminite+"");
System.out.println(nowweek+"");
int dehour=0;
int deminite=0;
//获取延迟时间
if(nowweek==2 || nowweek==3 || nowweek==5){

if(nowminite<=30 && nowhour<=20){
deminite=30-nowminite;
dehour=20-nowhour;
}
else if(nowminite>30 && nowhour<=20){

deminite=90-nowminite;
dehour=19-nowhour;
}
else if (nowminite<=30 && nowhour>20) {

deminite=30-nowminite;
dehour=44-nowhour;
}
else {
deminite=90-nowminite;
dehour=43-nowhour;
}}
else if(nowweek==4 || nowweek==6 || nowweek==7 || nowweek==1){

if(nowminite<=30 && nowhour<=17){
deminite=30-nowminite;
dehour=17-nowhour;
}
else if(nowminite>30 && nowhour<=17){

deminite=90-nowminite;
dehour=16-nowhour;
}
else if (nowminite<=30 && nowhour>17) {

deminite=30-nowminite;
dehour=41-nowhour;
}
else {
deminite=90-nowminite;
dehour=40-nowhour;
}

}
//延迟时间为K分钟
int k= dehour*60 + deminite;

return k;

}

}

Answer 2

弹出来的时候你就可以设置为不再弹出了

Answer 3

是不是jdk更新提示呀,能截个图来看看比较好.
如果是更新的话,你安提示去取消更新就可以了.或你用360优化下禁止他在后台运行试试看.
