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？
成都創(chuàng)新互聯(lián)公司服務項目包括海安網(wǎng)站建設、海安網(wǎng)站制作、海安網(wǎng)頁制作以及海安網(wǎng)絡營銷策劃等。多年來，我們專注于互聯(lián)網(wǎng)行業(yè)，利用自身積累的技術優(yōu)勢、行業(yè)經(jīng)驗、深度合作伙伴關系等，向廣大中小型企業(yè)、政府機構等提供互聯(lián)網(wǎng)行業(yè)的解決方案，海安網(wǎng)站推廣取得了明顯的社會效益與經(jīng)濟效益。目前，我們服務的客戶以成都為中心已經(jīng)輻射到海安省份的部分城市，未來相信會繼續(xù)擴大服務區(qū)域并繼續(xù)獲得客戶的支持與信任！
用到UI嗎？
把每個雨滴當做對象，抽象出來一個雨滴的類，里面包含雨落下的方向，速度，和失效的條件（落到地上了）。
再建立一個包含所有雨滴的容器，UI展示是通過容器里面獲得的雨點對象來展示。
這樣，容器里面每多出一個雨點對象，頁面上就多出一個雨點。用完的對象從容器里面拿出來就好
Java 源代碼的編碼問題
//我寫了一個程序，你把文字復制到文本框中點轉碼按鈕，就可以了
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTextArea;
public class Class1 extends JFrame {
private final class AT implements ActionListener {
public void actionPerformed(ActionEvent e) {
jta.setText(fixString(jta.getText()));
}
}
public static void main(String[] args) {
JFrame jf = new Class1();
}
JTextArea jta = new JTextArea();
public Class1() {
setSize(400, 400);
setDefaultCloseOperation(EXIT_ON_CLOSE);
JButton jb = new JButton("轉碼");
jb.addActionListener(new AT());
add(jta);
add("North", jb);
setVisible(true);
}
String fixString(String s) {
while (true) {
int index = s.indexOf("\\u");
if (index != -1) {
String s1 = s.substring(index, index + 6);
if (s1.matches("\\\\u[0-9A-F]{4}")) {
char c = (char) Integer.parseInt(s1.replace("\\u", ""), 16);
s = s.substring(0, index) + c + s.substring(index + 6);
}
} else {
break;
}
}
return s;
}
}
