Q3: java：使用数组，循环，if判断及随机数工具类完成彩票生成器
按照彩票35选7java代码你彩票35选7java代码的要求编写彩票35选7java代码的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
