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

JAVA编程，玫瑰2元一支，百合3元一支，菊花5元一支，康乃馨6元一支，20元正好花完没种各多少支

public static void main(String[] args) {

        for(int m = 0;m=10;m++) {//玫瑰,全买,对多买10只

            for(int b = 0;b=7;b++) {//百合,全买,对多买7只

                for(int j = 0;j=4;j++) {//菊花全买,对多买4只

                    for(int k = 0;k=4;k++) {//康乃馨全买,对多买4只

                        int total = 2*m+3*b+5*j+6*k;

                        if(20==total) {

                            System.out.println("玫瑰买"+m+"支,百合买"+b+"支,菊花买"+j+"支,康乃馨买"+k+"支");

                        }

                    }

                }

            }

        }

    }

java编程问题

之一题

int a=111

try{

int b=parseInt("888");

int c=a+b;}catch(NumberFormatException e){ System.out.println("大连市三个汉字不能转换成整数")}

第二题

String colour="红色";

String use="情人节礼物";

String xiangzheng="爱情";

double onemoney=8.8;

double buy=999;

public void showflower(){ System.out.println("colour+use+xiangzheng")}

public void showmoney(){System.out.println("999朵要花"+onemoney*buy)}

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

之一个：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:

之一步:把如下代码加入body区域中

script language="JavaScript"

!--

Pic=new Array('photo/04261.gif','photo/04262.gif','photo/04263.gif','photo/04264.gif','photo/04265.gif')

for(i=0; i Pic.length; i++)

}

amount=Pic.length;

ns=(document.layers)?1:0;

if (ns){

for (i=0; i amount; i++){

document.write("LAYER NAME='netscape"+i+"' LEFT=0 TOP=0img name='netpics' src="+load[i].src+"/LAYER")}

}

else{

document.write("div style='position:absolute;top:0px;left:0px'div style='position:relative'");

for (i=0; i amount; i++){

document.write("img id='explorer' src='"+load[i].src+"' style='position:absolute;top:0px;left:0px'")}

document.write("/div/div")

}

VB=0;

HB=0;

R=new Array();

PB=new Array();

RD=new Array();

Y=new Array();

X=new Array();

}

function Curve(){

plusMinus=new Array(1,-1,2,-2,3,-3,0,1,-1,0,5,-5)

for (i=0; i amount; i++){

R[i]=Math.floor(Math.random()*plusMinus.length);

RD[i]=plusMinus[R[i]];

}

setTimeout('Curve()',1500);

}

function MoveRandom(){

var H=(document.layers)?window.innerHeight:document.body.clientHeight;

var W=(document.layers)?window.innerWidth:document.body.clientWidth;

var YS=(document.layers)?window.pageYOffset:document.body.scrollTop;

var XS=(document.layers)?window.pageXOffset:document.body.scrollLeft;

for (i=0; i amount; i++){

BY[i]=-load[i].height;

BX[i]=-load[i].width;

PB[i]=D[i]+=RD[i];

y = SP[i]*Math.sin(PB[i]*Math.PI/180);

x = SP[i]*Math.cos(PB[i]*Math.PI/180);

if (D[i] 0) D[i]+=360;

Y[i]+=y;

X[i]+=x;

VB=180-D[i];

HB=0-D[i];

//Corner rebounds! not necessary but looks nice.

if ((Y[i] 1) (X[i] 1)) {Y[i]=1;X[i]=1;D[i]=45;}

if ((Y[i] 1) (X[i] W+BX[i])) {Y[i]=1;X[i]=W+BX[i];D[i]=135;}

if ((Y[i] H+BY[i]) (X[i] 1)) {Y[i]=H+BY[i];X[i]=1;D[i]=315;}

if ((Y[i] H+BY[i]) (X[i] W+BX[i])) {Y[i]=H+BY[i];X[i]=W+BX[i];D[i]=225;}

//Edge rebounds!

if (Y[i] 1) {Y[i]=1;D[i]=HB;}

if (Y[i] H+BY[i]) {Y[i]=H+BY[i];D[i]=HB;}

layer.top=Y[i]+YS;

layer.left=X[i]+XS;

}

setTimeout('MoveRandom()',10);

}

function sTaRt(){Curve();MoveRandom()}

//--

/script

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:

之一步:把如下代码加入body区域中

script LANGUAGE="JavaScript"

function init() {

setTimeout("shake(3)",1000);

// setTimeout("this.focus()",4000);

setTimeout("shake(3)",4100);

}

function shake(n) {

if (self.moveBy) {

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);

}

/script

script language="JavaScript"

!-- begin

var max=0;

function textlist()

{

max=textlist.arguments.length;

for (i=0; imax; i++)

this[i]=textlist.arguments[i];

}

tl=new textlist

(

var x=0; pos=0;

var l=tl[0].length;

function textticker()

{

document.tickform.tickfield.value=tl[x].substring(0,pos)+"_";

if(pos++==l)

{

pos=0;

setTimeout("textticker()",1000);

x++;

if(x==max) x=0; l=tl[x].length;

}

else

setTimeout("textticker()",50);

}

// end --

/script

form name="tickform"input type=text name="tickfield" size=33/form

第二步:把如下代码加入body区域中body bgcolor=#000000" onload="init();textticker()"

能把你的就这么多了 看你的了
