对于初学者有所帮助，java随机产生双色球

public static void main(String[] args) {
List<Integer>
list = new LinkedList<Integer>();
for(int
i=0;i<32;i++){
list.add(i+1);
}
Random
random = new Random();
int[]
arr = new int[6];
for(int
i = 0;i<arr.length;i++){
int
num = random.nextInt(list.size());
Integer
remove = list.remove(num);
arr[i]
= remove;
System.out.print(list.size()+"----");
}
System.out.println();
Arrays.sort(arr);
int
nextInt = random.nextInt(16);
for(int
i=0;i<arr.length;i++){
if(i==0){
System.out.print("红色号码球："+arr[0]+"
  ");
}else{
if(i==arr.length-1){
System.out.println("绿色号码球："+nextInt);
break;
}
System.out.print(arr[i]+"
  ");
}
}
