最简单的彩票实现代码set应用,希望大家一起探讨

public class Caipiao {
static void generate() {
Set<Integer> set = new TreeSet<Integer>();
Set<Integer> set2 = new HashSet<Integer>();
Random rd = new Random();
while(set.size()<6){
set.add(rd.nextInt(36)+1);
}System.out.print("红球"+sum+"号是"+set);
set2.add(rd.nextInt(16)+1);
System.out.println("蓝球是:"+set2);

}

public static void main(String args[]) {
 
System.out.println(" 中国福利彩票");
 
generate();
System.out.println();
}
