站在用戶的角度思考問題，與客戶深入溝通，找到赤壁網(wǎng)站設(shè)計與赤壁網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗，讓設(shè)計與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個性化、用戶體驗好的作品，建站類型包括：成都做網(wǎng)站、成都網(wǎng)站制作、企業(yè)官網(wǎng)、英文網(wǎng)站、手機(jī)端網(wǎng)站、網(wǎng)站推廣、域名與空間、網(wǎng)頁空間、企業(yè)郵箱。業(yè)務(wù)覆蓋赤壁地區(qū)。

import java.awt.Color;

public class TipPanel extends JPanel implements Runnable{

private static final long serialVersionUID = 1L;

//偶數(shù)打印，畫面板

int time=0;

public void paintComponent(Graphics g){

super.paint(g);

g.fillRect(0, 0, MainTank.getWidthOfGame(), MainTank.getHeightOfGame());//繪制提示窗口

if (time%2==0){//偶數(shù)打印，畫面板，造成閃爍效果

g.setColor(Color.ORANGE);

Font font=new Font("華文楷體",Font.BOLD,30);

g.setFont(font);//選用字體

g.drawString("Ready", 140, 130);

}

}

@Override

public void run() {

while (true){

try{

Thread.sleep(250);

}catch (Exception e){

e.getMessage();

}

time++;//繪圖開關(guān)

this.repaint();

}

}

}//TipPanel

類似的，修改下就行

用Java語言打星星

第一個的代碼如下,可以改變i的數(shù)值來控制X形狀的大小

class Test

{

public static void main(String[] args)

{

int i=3;

int j=i*2-1;

int k,l;

for(;j0;j--)

{

k=(i-1)-Math.abs(j-i);

l=Math.abs(j-i)*2-1;

for(;k0;k--)

{

System.out.print(" ");

}

System.out.print("*");

if(l0)

{

for(;l0;l--)

{

System.out.print(" ");

}

System.out.print("*");

}

System.out.print("\n");

}

}

}

你第二個我也沒看明白,不過思路應(yīng)該都差不多,你根據(jù)這一個自己琢磨琢磨吧,關(guān)鍵問題就在k和l的計算上.

頁面特效:下星星的代碼(JAVA代碼)

以下的代碼就可以，lz自己在*的地方填入星星的圖片就可以了
