Java 通过Math.random() 生成6位随机数

 1 public static void main(String[] args) {
 2         String sjs="";
 3         
 4         for (int i = 0; i < 6; i++) {
 5             int max=9,min=0;
 6             int ran2 = (int) (Math.random()*(max-min)+min); 
 7             System.out.println(ran2 );
 8             sjs=ran2+sjs;
 9         }
10         System.out.println("6位随机数： "+sjs );
11     }
