java代碼時鍾

『壹』 用java編寫一個時鍾的程序

我給你做了一下:(第二個功能你自己加吧)
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.Date;
import java.text.*;

public class TestTimer extends JFrame implements ActionListener{
Timer timer;
JLabel display = new JLabel();
SimpleDateFormat dateFmt = new SimpleDateFormat("hh:mm:ss");

TestTimer(){

getContentPane().setLayout(new FlowLayout());
timer = new Timer(1000,this);
timer.setRepeats(true);
timer.setInitialDelay(1000);
timer.start();
getContentPane().add(display);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(200,100);
setVisible(true);

} // TestTimer

public void actionPerformed(ActionEvent e){

if(e.getSource() == timer){

display.setText(dateFmt.format(new Date()));
}

} // actionPerformed

public static void main(String[] args){

TestTimer tt = new TestTimer();
}
} // TestTimer

『叄』 如何用java做這樣的時鍾

class Clock{
private int hourse;
private int minute;
private int second;

public Clock(){
this.hourse=0;
this.minute=0;
this.second=0;

}

public void incSecond(){
this.second+=1;
}

public void toTime(){
if(this.hourse>24){this.hourse=0;}
if(this.minute>60){this.hourse+=1;this.minute-=60;}
if(this.second>60){this.minute+=1;this.second-=60;}
System.out.printf(hourse+":"+minute+":"+second);
}

public void setHourse(int hourse) {
this.hourse = hourse;
}

public void setMinute(int minute) {
this.minute = minute;
}

public void setSecond(int second) {
this.second = second;
}
}

public class test {
public static void main(String[] args) {
Clock c=new Clock();
c.setMinute(66);//測試數據
c.setSecond(61);
c.toTime();//輸出1：7：1
}
}
基本功能實現。

『肆』 JAVA時鍾代碼解釋

lz這個代碼有什麼看不懂的 如果這個代碼看不懂的話 建議你從基礎的開始學習吧
首先可以看到extends JFrame implements ActionListener 關於ActionListener 介面和JFrame 類lz有必要去看看 加入api慢慢研究下吧

int x,y,x0,y0,r,h,olds_x,olds_y,oldm_x,oldm_y,oldh_x,oldh_y,ss,mm,hh,old_m,old_h,ang;
這些東西我也看不懂 因為你的代碼不完整
final double RAD=Math.PI/180; 這個應該是算一個弧度吧

super("made by mcj and wdh"); 這句無意義 是父類的代碼

setDefaultCloseOperation(3);這個方法是什麼？？代碼不完整

setSize(300,300);設置窗體大小

setBackground(Color.white);設置背景色

setLocation(300,150); 定位
setResizable(false);不調整大小

setVisible(true);可見

後面的就沒有代碼了

『伍』 用 java 寫一個clock的類，100毫秒的時鍾 求代碼。。越簡單越好。。最好有注釋

這里有一個時鍾的類，你看一下吧，不明白你的 100毫秒的時鍾 是什麼意思。

『柒』 怎樣用java 程序寫一個時鍾程序

面向對象思想寫成：

下面是一個顯示器類

publicclassDisplay{
privateintvalue;//現在的值
privateintlimit;//上限值
Display(intlimit){
this.limit=limit;
}
publicvoidincrease(){
value++;
if(value==limit){
value=0;
}
}
publicintgetValue(){
returnvalue;
}
publicstaticvoidmain(String[]args){
Displayd=newDisplay(24);
for(;;){
d.increase();
System.out.println(d.getValue());
}
}
}

下面創建一個時鍾對象：

publicclassClock{
privateDisplayh=newDisplay(24);
privateDisplaymin=newDisplay(60);
privateDisplays=newDisplay(60);
publicvoidstart(){
for(;;){
s.increase();
if(s.getValue()==0){//如果分重置，小時+1
min.increase();
if(min.getValue()==0){//如果分重置，小時+1
h.increase();
}
}
System.out.printf("%02d:%02d:%02d
",h.getValue(),min.getValue(),s.getValue());//格式輸出
}
}
publicstaticvoidmain(String[]args){
Clockclock=newClock();
clock.start();
}
