Math. The random randomly generated [0, 1) int, take 10 after cycle 20 times

CodePudding user response:

In Java. The util package below there is a kind of Random, instantiate objects of the Random class

The Random Random=new Random ();

The random nextInt (10);//generated is an integer greater than or equal to zero and less than 10

System. The out. Println (" first "+ (I + 1) +" is a Random number is: "+ new Random () nextInt (10));
