Q1: 35选7 用java代码实现
public class mainClass {
public mainClass() {
}
public static void main(String []args){
int [] num = new int[35];
boolean [] flag = new boolean[35];
int count = 0;
for(int i=0;i35;i++)
{
num[i] = i + 1;
flag[i] = true;
}
while(count!=7){
int k=(int)(Math.random()*35);
if(flag[k]){
System.out.println(num[k]);
flag[k]=false;
count++;
}
}
}
}

Q4: java：使用数组，循环，if判断及随机数工具类完成彩票生成器
按照你的要求编写的35选7彩票生成器的Java程序如下
import java.util.Arrays;
public class F {
public static String random() {
int []a=new int[7];
int count=0;
while(count7){
boolean flag=false;
int tmp=(int)(Math.random()*35)+1;
for(int i=0;ia.length;i++){
if(tmp==a[i]){
flag=true;
}
}
if(flag==false){
a[count]=tmp;
count++;
}
}
//对选出的7个数排序
Arrays.sort(a);
//输出35选7的结果 并在个位数前补0
String s="";
for(int i=0;ia.length;i++){
if(i==a.length-1){
if(a[i]10){
s=s+"0"+a[i];
}else{
s=s+a[i];
}
}else{
if(a[i]10){
s=s+"0"+a[i]+",";
}else{
s=s+a[i]+",";
}
}
}
return s;
}
public static void main(String[] args) {
System.out.println(random());
}
}
运行结果
05,10,14,16,22,28,31
多试几次会有不同结果
Q5: java 程序 在线等！！！
import java.io.*;
public class CaipiaoOne {
public static void main(String[] args) throws Exception {
int n = 0;
int[] num = new int[7];
System.out.print("请输入要生成的注数：");
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
n = Integer.parseInt(in.readLine());
int tmp = 0;
for(int i=0;in;i++){
for(int j=0;j7;j++){
tmp=(int)(Math.random()*36);
while(tmp==0)
tmp=(int)(Math.random()*36);
System.out.print(tmp+" ");
}
System.out.println();
}
}
}
//Lottery类
import java.util.Date;
