java彩票系統

① 如何使用java語言程序模擬彩票抽獎系統中的加住

可以考慮用一個list來保存注

改list裡面元素表示為
class item{
double money;//加註金額
double count; //加註次數
}

② Java 實現彩票程序

importjava.util.ArrayList;
importjava.util.Collections;
importjava.util.List;
importjava.util.Random;

publicclassMain{

	publicstaticvoidmain(String[]args){
		//紅球選6
		List<Integer>redBall=newArrayList<Integer>();
		for(inti=0;i<33;i++){
			redBall.add(i+1);
		}
		System.out.println("開獎紅球："+select(redBall,6));
		//籃球16選1
		List<Integer>blueBall=newArrayList<Integer>();
		for(inti=0;i<16;i++){
			blueBall.add(i+1);
		}
		System.out.println("開獎藍球："+select(blueBall,1));
	}
	
	publicstaticList<Integer>select(List<Integer>list,intcount){
		List<Integer>selectedList=newArrayList<Integer>();
		Randomrandom=newRandom();
		for(inti=0;i<count;i++){
			intindex=random.nextInt(list.size());
			Integernumber=list.get(index);
			selectedList.add(number);
			list.remove(index);
		}
	Collections.sort(selectedList);
		returnselectedList;
	}

}

③ 用JAVA編寫一個福利彩票機選模擬器，使用隨機數方法

自己寫的，不懂可以問我
import java.util.Random;

import java.awt.*;

import java.awt.event.*;

public class shuangSeQiu implements ActionListener{

int i,k;
static int rm,rr;
int [] a = new int [33];
Frame f = new Frame("雙色球隨機數");

TextField tf = new TextField();
Random rd = new Random();
public shuangSeQiu()
{
for(i=0;i<33;i++)
{
a[i] = i;
}

f.setLayout(new BorderLayout());
f.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
});
}

public void init()
{

tf.addActionListener(this);

Button b = new Button("開始");
b.addActionListener(this);
f.add(tf,"North");
f.add(b);
f.setSize(300,300);
f.setVisible(true);

}

public void actionPerformed(ActionEvent e)
{
if(e.getActionCommand().equals("開始"))
//tf.setText(""+(rd.nextInt(33)+1)+" "+(rd.nextInt(33)+1)+" "+(rd.nextInt(33)+1)+" "+(rd.nextInt(33)+1)+" "+(rd.nextInt(33)+1)+" "+(rd.nextInt(33)+1)+" 藍色球號碼："+(rd.nextInt(15)+1));
{
/*rr = new Random().nextInt(33);
rm = new Random().nextInt(33);*/
for(i=0;i<33;i++)
{
rr = new Random().nextInt(33);
rm = new Random().nextInt(33);
System.out.print(rr+" ");
k=a[rm];
a[rm]=a[rr];
a[rr]=k;
}
tf.setText("紅色球號碼："+(a[0]+1)+" "+(a[1]+1)+" "+(a[2]+1)+" "+(a[3]+1)+" "+(a[4]+1)+" "+(a[5]+1)+" 藍色球號碼："+(rd.nextInt(15)+1));
}
}
public static void main(String[] args)//throws Exception
{
new shuangSeQiu().init();
}
}

④ java的彩票

import java.util.ArrayList;
import java.util.Random;
import java.util.Scanner;

/**
* 測試彩票類
* @author doulmi
*
*/
public class LotteryDemo {
public static void main( String[] args ) {
Scanner scanner = new Scanner( System.in );
System.out.print( "請輸入要購買的注數:" );
System.out.println();

int buyN = 0;
if ( scanner.hasNextInt() ) {
buyN = scanner.nextInt();
} else {
System.out.println( "請輸入正確的數字" );
}

for ( int i = 0; i < buyN; i ++ ) {
Lottery lot = new Lottery();
lot.generate();
System.out.print( "第" );
System.out.print( i );
System.out.print( "注" );
lot.printData();
}
}
}

/**
* 彩票類
* @author Administrator
*
*/
class Lottery {
private static final int NUM_TO_GETOUT = 7;
//能產生的最大數值為99
private static final int MAX_NUM = 35;
public ArrayList< Integer > list;
private int[] result;

public Lottery() {
list = new ArrayList< Integer >();
for ( int i = 1; i <= MAX_NUM; i ++ ) {
list.add( i );
}
result = new int[ NUM_TO_GETOUT ];
}

public void generate() {
Random r = new Random();
for ( int i = 0; i < NUM_TO_GETOUT; i ++ ) {
result[ i ] = list.remove( r.nextInt( list.size() ) );
}
}

/**
* 關於票頭的列印。。我不知道票頭是什麼。
*/
public void pringTitle() {

}

/**
* 實現號碼的列印
*/
public void printData() {
for ( int n : result ) {
System.out.print( n );
System.out.print( " " );
}
System.out.println();
}
}

⑤ 用java編寫一個彩票抽獎程序

一個簡單的程序。

⑥ 用Java程序寫一個彩票的模擬程序生成6個紅球（1-33的隨機數），1個藍球（1-16的隨機數），隨機數可以重復

(){
		Randomrandom=newRandom();
		intredball[]=newint[6];
		StringBufferstringBuf=newStringBuffer();
		for(inti=0;i<6;){
			inttemp=random.nextInt(33)+1;
			if(this.isGenerated(redball,temp))
				continue;
			elsestringBuf.append((redball[i++]=temp)+(i==6?"":","));
		}

		stringBuf.append("|"+(random.nextInt(16)+1));
		returnstringBuf.toString();
	}
	privatebooleanisGenerated(int[]scope,inttarget){
		if(scope==null)returnfalse;
		for(inti=0;i<scope.length;i++)
			if(target==scope[i])returntrue;
		returnfalse;
	}
