編寫一個java程序，實(shí)現(xiàn)如下功能？

這個題可以使用switch-case語句來解決，首先創(chuàng)建簡單文本掃描器，然后從鍵盤讀入0~9或字母a，然后通過開關(guān)語句進(jìn)行匹配，進(jìn)而輸出結(jié)果，代碼如下：

常熟ssl適用于網(wǎng)站、小程序/APP、API接口等需要進(jìn)行數(shù)據(jù)傳輸應(yīng)用場景，ssl證書未來市場廣闊！成為成都創(chuàng)新互聯(lián)的ssl證書銷售渠道，可以享受市場價格4-6折優(yōu)惠！如果有意向歡迎電話聯(lián)系或者加微信：028-86922220（備注：SSL證書合作）期待與您的合作！

在main()方法中調(diào)用，在控制臺輸入，驗(yàn)證輸出，效果如下：

怎么用JSP編一個關(guān)于星座的程序

import java.io.*; import javax.servlet.*; import javax.servlet.http.*; import java.util.*; public class xingzuo extends HttpServlet { public void doGet(HttpServletRequest req,HttpServletResponse res) throws IOException { res.setContentType("text/html"); res.setCharacterEncoding("GB2312"); PrintWriter out = res.getWriter(); String getmonth = req.getParameter("month"); int month = new Integer(getmonth).intValue(); String getday = req.getParameter("day"); int day = new Integer(getday).intValue(); String test=req.getParameter("T1"); boolean err=false; int xingzuonumber=0; int fenjie[]={21,19,21,21,22,22,23,24,24,24,23,22}; int zuida[]={31,29,31,30,31,30,31,31,30,31,30,31}; String xingzuo[]={"水平座","雙魚座","白羊座","金牛座","雙子座","巨蟹座","獅子座","處女座","天秤座","天蝎座","人馬座","山羊座"}; String xingge[]=new String[12]; xingge[0]="這個星座常被稱為'天才星座'或'未來星座'。"; xingge[7]="處女座的特色是有豐富的知性，做事一絲不茍，"; xingge[8]="天秤座的人愛好美與和諧，也相當(dāng)仁慈并富有同情心，"; xingge[9]="這個星座的人有著強(qiáng)烈的第六感、神秘的探視能力及吸引力，"; xingge[10]="這個星座出生的人崇尚自由、無拘無束及追求速度的感覺，"; xingge[11]="就像是只走在高山絕壁的山羊一樣穩(wěn)健踏實(shí)，"; out.print("html"); out.print("body bgcolor=#3300ff"); out.print("center"); if(zuida[month-1]day) { err=true; }; if(day= fenjie[month-1]) { xingzuonumber=(month%12)+1; }else{xingzuonumber=month;}; if (err) { out.print("您輸入的生日有錯誤，請重新輸入"); }else{ out.print("table border=1"+"tr"); out.print("td"); out.print("img src = 'image/"+ xingzuonumber + ".jpg'/td"); out.print("td"); out.print("您的生日是"+month+"月"+day+"日"+"您的星座是"+xingzuo[(xingzuonumber+10)%12]+"這個星座的特點(diǎn)是："+xingge[(xingzuonumber+10)%12]+"font color=reda href = xingzuo.jsp點(diǎn)擊返回首頁"); } //out.print(xingzuo[0]); out.print("/tr/table/center"); out.print("/body"); out.print("/html"); } }

用JAVA寫星座運(yùn)勢，算法怎么寫？

經(jīng)過一定的選擇過后會羅列出一大段運(yùn)勢數(shù)據(jù),而這些是按一定次序進(jìn)行羅列出來的.

設(shè)置一組數(shù)字矩陣,矩陣中每個數(shù)字都對應(yīng)于一項(xiàng)星辰運(yùn)勢

每個星座可以設(shè)置多個選項(xiàng),除了星座選擇外,還可以根據(jù)相同星座的不同日期段(如0號到3號,3號到6號.....),以及血型(o,a,b...)或者屬相(鼠,牛,虎....)

舉例:

數(shù)據(jù)假設(shè)分四類,一日期,二血型,三屬相,四星座

日期 a1,a2,a3,a4....

血型 b1,b2,b3,b4....

屬相 c1,c2,c3,c4....

星座 d1,d2,d3,d4....

獲取數(shù)據(jù)用戶輸入信息,如a2,b3,c1,d2

從而獲取對應(yīng)位置的數(shù)據(jù)存儲地址,從地址讀出數(shù)據(jù)并顯示

可以對用戶輸入信息做一定的運(yùn)算,根據(jù)前后數(shù)據(jù)的關(guān)系,如輸出信息分四部分,分別為y1=f(abcx),y2=f(abcx),y3=f(abcx),y4=f(abcx),經(jīng)過一定運(yùn)算后將其特定地址的內(nèi)容顯示出來即可,只要注意處理運(yùn)算超界問題 程序就可以很好的運(yùn)行了

一個算星座的程序 會的幫下 急用

用java編一個程序能通過用戶輸入的生日判斷用戶的星座。請大神們給點(diǎn)提示或者思路吧。規(guī)定不能自定義方法
