Question

Roll dice java program

The program simulates a dice roll by generating a random integer between 1 and 6

Answer 1

Hope this will help you. If you have any doubt please let me know.

If you want any modification in the program please let me know. I will do it, because there was no other instruction provided in the program.

Please go through all the notes.

Notes: There were no other instructions or restrictions provided in the problem statement except generate Random number.

There are 2 ways we can generate a random number 1) using Math class and 2) using a Random Class.

Over here not specified which one to use hence both are provided in code. Method using a math class is commented if you want to use this uncomments that line.

All line of code is commented.

A screenshot of the output is also attached.

If you want any modification in the program please let me know. I will do it.

   System.out.print("Face values of the dice is: "); /*print message*/
   n=rand.nextInt(6)+1;/*random number generator between 1 and 6 nextInt(6) generate random number between 0 and 5 and adding 1 into it makes between 1 to 6*/
   //n=(int) (Math.random()*6+1);/*2nd method to generate a random number */
   System.out.println(n); /*printing a dice value*/
   System.out.print("Do you want to countinue? (Press Y for yes, or any other character for no.)"); /*asking for other input*/
   ch=sc.next().charAt(0);/*scanning a first char*/
}while(ch=='Y'||ch=='y');/*if ch==y again roll dice*/
   System.out.println("-----SIMULATION ENDS---------");/*printing a msg*/
   }
}
