}

public

void

start()

timer

new

Thread(this);

生成Thread(多線程程序)的對象實(shí)體

timer.start();

啟動生成的線程

}

public

void

stop()

{

timer.stop();

停止線程的工作

timer

null;

放掉Thread對象

}

public

void

run()

改方法用來定義線程體，一旦線程被啟動執(zhí)行，就開始執(zhí)行這個(gè)方法

{

while

(timer

null)

{

try

{

Thread.sleep(150);

使當(dāng)前正在執(zhí)行的線程進(jìn)入睡眠時(shí)間由參數(shù)millis確定，

單位時(shí)間是毫秒，當(dāng)這個(gè)時(shí)間過去，線程即可運(yùn)行的

while

(timer

null)

{

try

{

Thread.sleep(150);//

使用當(dāng)前正在執(zhí)行的線程進(jìn)入睡眠時(shí)間由參數(shù)

millis確定,單位是毫秒，當(dāng)這個(gè)時(shí)間過去，線程即為可運(yùn)行的

}

catch

(InterruptedException

{

}

repaint();

repaint所做的事其實(shí)是去調(diào)用方法uadate重畫效應(yīng)用程序

}

timer

null;

}

catch

(InterruptedException

{

}

所做的工作是先將整個(gè)效應(yīng)用程序區(qū)域清除，再去調(diào)用paint，完成重畫的動作

public

void

update(Graphics

{

paint(g);

}

怎樣用java 程序?qū)懸粋€(gè)時(shí)鐘程序

面向?qū)ο笏枷雽懗桑?/p>

下面是一個(gè)顯示器類

public?class?Display?{

private?int?limit;//上限值

Display(?int?limit)?{

this.limit?=?limit;

}

public?void?increase()?{

}

public?static?void?main(String[]?args)?{

Display?d?=?new?Display(24);

for(;;)?{

d.increase();

System.out.println(d.getValue());

if(min.getValue()?==?0){//如果分重置，小時(shí)+1

h.increase();

}

System.out.printf("%02d:%02d:%02d\n",h.getValue(),?min.getValue(),s.getValue());//格式輸出
