求大神帮忙用*打印出一朵玫瑰，或者代码都行（JAVA）
没看懂你的需求，cmd控制台运行class很简单，要在哪展示玫瑰花呢？txt？浏览器页面？cmd窗口？
玫瑰花是用字符串拼接的？还是img图片类型？ 需求不一样难度也不一样哦

我已经在你的第二个百度号回答过了，你的技术要求我好多没用到，但完全符合你的功能，你可以自行修改下。我新手，能力不是很高，希望帮到您
求个小代码，一打开全屏幕就是玫瑰花飘飘的，过几秒后就现在中秋快乐。
java jsp的啊
第一个：把如下代码加入body区域中，设置文字的话你自己弄吧
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
第二种：建议你用这个，你可以在加几个图片
脚本说明:
第一步:把如下代码加入body区域中

第二步:
把如下代码加入body区域中body bgcolor="#ffffff" onLoad="if (document.all||document.layers) sTaRt()"
第三个：这个是文字的显示，你自己决定采用上面那个后加进去
脚本说明:
第一步:把如下代码加入body区域中

能把你的就这么多了 看你的了
