求如何使用java編寫連續(xù)下雨的程序！只求思路！

不知道你想要干什么……什么連續(xù)下雨？

目前創(chuàng)新互聯(lián)已為超過(guò)千家的企業(yè)提供了網(wǎng)站建設(shè)、域名、虛擬空間、網(wǎng)站托管、企業(yè)網(wǎng)站設(shè)計(jì)、臨澧網(wǎng)站維護(hù)等服務(wù)，公司將堅(jiān)持客戶導(dǎo)向、應(yīng)用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協(xié)力一起成長(zhǎng)，共同發(fā)展。

用到UI嗎？

把每個(gè)雨滴當(dāng)做對(duì)象，抽象出來(lái)一個(gè)雨滴的類，里面包含雨落下的方向，速度，和失效的條件（落到地上了）。

再建立一個(gè)包含所有雨滴的容器，UI展示是通過(guò)容器里面獲得的雨點(diǎn)對(duì)象來(lái)展示。

這樣，容器里面每多出一個(gè)雨點(diǎn)對(duì)象，頁(yè)面上就多出一個(gè)雨點(diǎn)。用完的對(duì)象從容器里面拿出來(lái)就好

怎么使用java代碼根據(jù)所提供的天氣來(lái)寫出不出去，比如先說(shuō)，晴天.風(fēng).濕

氣溫高,則氣壓低,因?yàn)楦邭鉁厥箍諝馀蛎?使相對(duì)下的空氣密度變大. 氣溫高,氣壓低,濕度大時(shí),一般會(huì)下雨. 有霧時(shí),氣溫高,蒸發(fā)量大,一般是晴天. 氣溫適中時(shí),一般是陰天,因?yàn)殛幪鞎r(shí)云比較多,大量的云反射了太陽(yáng)的大部分熱量,同時(shí)也逆反射了地球的熱量,這樣就起到了保溫作用,溫度就不會(huì)太熱,也不會(huì)太低

我想用JAVA 做一個(gè)動(dòng)畫為什么做不出來(lái)，代碼寫出來(lái) 求高手指教

java可以做動(dòng)畫，但是不適合做動(dòng)畫。每個(gè)東西都有其使用的領(lǐng)域。

好比java適合寫應(yīng)用程序，C適合寫嵌入式程序，flash適合做動(dòng)畫，

求java做動(dòng)畫代碼

JAVA動(dòng)畫

用Java畫動(dòng)畫很簡(jiǎn)單，讓一個(gè)線程自己定時(shí)調(diào)用自己即可，記得要設(shè)置一個(gè)退出（結(jié)束）條件。

import org.eclipse.swt.SWT;

import org.eclipse.swt.layout.FillLayout;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.Shell;

import org.eclipse.swt.widgets.Text;

public class Animation {

final static int DELAY = 500;

public static void main(String[] args) {

final Display display = new Display();

final Shell shell = new Shell(display);

shell.setLayout(new FillLayout());

final Text text = new Text(shell, SWT.BORDER);

text.setText("0");

new Runnable() {

public void run() {

if (shell.isDisposed())

return;

text.setText("" + (Integer.parseInt(text.getText()) + 1));

Display.getDefault().timerExec(DELAY, this);

}

}.run();

shell.pack();

shell.open();

while (!shell.isDisposed()) {

if (!display.readAndDispatch())

display.sleep();

}

display.dispose();

}
