Java 通过Math.random() 生成6位随机数

 public static void main(String[] args) {
         String sjs="";

         for (int i = 0; i < 6; i++) {
             int max=9,min=0;
             int ran2 = (int) (Math.random()*(max-min)+min);
             System.out.println(ran2 );
             sjs=ran2+sjs;
         }
         System.out.println("6位随机数： "+sjs );
     }
