Its kind of simple question thu but its so hard for me,
Im using the Random class to generate randomize numbers but my applicatiom must those numbers as a String and not integers. How can I parse the returned random int into a String?
String label = random.nextInt(70).toString(); ????

| | gen.nextInt(70) + 1;
nextInt(n) gives an integer in the range of 0 to n-1, so nextInt(70) +1 will give you an integer in the range of 1 - 70.

| | The nextInt(int) method returns a random number between 0 and the passed number, excluding the passed number. From this you get any range by adding or subtracting numbers.
Like to get a number from 1 to 70, first generate a number from 0 to 69 and add one. In code, "1+gen.nextInt(70)" | | Posts:114 Registered: 7/5/04 | Re: Parsing random integers into a Strings Jul 18, 2004 7:38 AM (reply 7 of 7) |
