三葉玫瑰并不是植物，你也說啦，是專門研究數(shù)學(xué)的。其實(shí)是一種三葉玫瑰線的 java代碼
S 3：
輸入下面程序用于輸出三葉玫瑰線的圖形，三葉玫瑰線的參數(shù)方程為：
x = r * sin(3t)* sin(t);y = r *sin(3t) * sin(t) 其中: 0 = t = 2 * 3.14159
#include stdio.h
#include math.h
#define RADIUS 12
#define PII 3.14159
void main(void)
{
char tx[2 * RADIUS + 1][2 * RADIUS + 1];
int nT;
int nX;
int nY;
double dbD;
for(nX = 0; nX 2 * RADIUS + 1; nX++)
{
for(nY = 0; nY 2 * RADIUS + 1; nY++)
{
tx[nX][nY] = '';
}
}
for(nT = 0; nT = 360; nT += 4)
{
dbD = nT * PII / 180;
nX = (int)(RADIUS * sin(3 * dbD) * sin(dbD)) + RADIUS;
nY = (int)(RADIUS * sin(3 * dbD) * cos(dbD)) + RADIUS;
tx[nX][nY] = '*';
}
for(nX = 0; nX 2 * RADIUS + 1; nX++)
{
for(nY = 0; nY 2 * RADIUS + 1; nY++)
{
printf("%2c", tx[nX][nY]);
}
printf("\n");
}
}
1.在電腦桌面，鼠標(biāo)右鍵單擊選擇 新建文本文檔，新建一個(gè)文本文檔。
2.選擇新建的文本，右鍵選擇重命名為，meigui.html，然后確定，選擇是。
3.用記事本打開文件，復(fù)制下面的代碼到文件中，保存。

4.然后用瀏覽器打開文件，是不是出現(xiàn)了一朵漂亮的 玫瑰花，大功告成。
java jsp的啊
第一個(gè)：把如下代碼加入body區(qū)域中，設(shè)置文字的話你自己弄吧
style
.drop { position: absolute; width: 3; filter: flipV(), flipH(); font-size: 40; color: blue }
/style
script language="javascript"
snow = false; // false-rain; true-snow
snowsym = " * " //These are the symbols for each
rainsym = " * " //You can put images here.
howmany = 15 //How many drops/snowflakes?
/**************Do not need to change anything below***********/
if(snow){sym = snowsym; speed=1; angle=10; drops=howmany}
else{sym = rainsym; speed=50; drops=howmany; angle=6}
movex = -speed/angle; movey = speed; count = 0;
function moverain(){
for(move = 0; move drops; move++){
xx[move]+=movex; yy[move]+=mv[move];
hmm = Math.round(Math.random()*1);
if(xx[move] 0){xx[move] = maxx+10;}
if(yy[move] maxy){yy[move] = 10;}
drop[move].left = xx[move]
drop[move].top = yy[move]+document.body.scrollTop;
}setTimeout('moverain()','1')}
/script
script language="javascript"
if (document.all){
drop = new Array(); xx = new Array(); yy = new Array(); mv = new Array()
ly = "document.all[\'"; st = "\'].style"
for(make = 0; make drops; make++){
document.write('div id="drop'+make+'" class=drop'+sym+'/div');
drop[make] = eval(ly+'drop'+make+st);
maxx = document.body.clientWidth-40
maxy = document.body.clientHeight-40
xx[make] = Math.random()*maxx;
yy[make] = -100-Math.random()*maxy;
drop[make].left = xx[make]
drop[make].top = yy[make]
mv[make] = (Math.random()*5)+speed/16;
drop[make].fontSize = (Math.random()*10)+20;
if(snow){col = 'white'}else{col = 'blue'}
drop[make].color = col;
}
window.onload=moverain
}
/script
第二種：建議你用這個(gè)，你可以在加幾個(gè)圖片
腳本說明:
第一步:把如下代碼加入body區(qū)域中
script language="JavaScript"

function MoveRandom(){

setTimeout('MoveRandom()',10);
}
function sTaRt(){Curve();MoveRandom()}
//--
/script
第二步:
把如下代碼加入body區(qū)域中body bgcolor="#ffffff" onLoad="if (document.all||document.layers) sTaRt()"
第三個(gè)：這個(gè)是文字的顯示，你自己決定采用上面那個(gè)后加進(jìn)去
腳本說明:
第一步:把如下代碼加入body區(qū)域中
script LANGUAGE="JavaScript"
function init() {
setTimeout("shake(3)",1000);

for (i = 10; i 0; i--) {
for (j = n; j 0; j--) {
self.moveBy(0,i);
self.moveBy(i,0);
self.moveBy(0,-i);
self.moveBy(-i,0);

}
}
setTimeout("shake(5)", 5000);
}

第二步:把如下代碼加入body區(qū)域中body bgcolor=#000000" onload="init();textticker()"
能把你的就這么多了 看你的了
public?static?void?main(String[]?args)?{
for(int?m?=?0;m=10;m++)?{//玫瑰,全買,對(duì)多買10只
for(int?b?=?0;b=7;b++)?{//百合,全買,對(duì)多買7只
for(int?j?=?0;j=4;j++)?{//菊花全買,對(duì)多買4只
for(int?k?=?0;k=4;k++)?{//康乃馨全買,對(duì)多買4只
int?total?=?2*m+3*b+5*j+6*k;
if(20==total)?{
System.out.println("玫瑰買"+m+"支,百合買"+b+"支,菊花買"+j+"支,康乃馨買"+k+"支");
}
}
}
}
}
}
沒看懂你的需求，cmd控制臺(tái)運(yùn)行class很簡(jiǎn)單，要在哪展示玫瑰花呢？txt？瀏覽器頁(yè)面？cmd窗口？
玫瑰花是用字符串拼接的？還是img圖片類型？ 需求不一樣難度也不一樣哦
