Java 1st method:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | /** * Generate Random Number within Range using Java * @author Deepak Verma * */ import java.util.concurrent.ThreadLocalRandom; public class Generate_Random_Number_within_Range_using_Java_Example_1 { public static void main(String args[]) { int minimum = 1; int maximum = 1000; System.out.println("Ten Random Numbers b/w 1 and 1000 are:"); // Generate 10 random numbers between 1 and 1000 for (int i = 0; i < 10; i++) { int randomNumber = ThreadLocalRandom.current().nextInt(minimum, maximum + 1); System.out.println(randomNumber); } } } |
Output:
1 2 3 4 5 6 7 8 9 10 11 12 13 | Ten Random Numbers b/w 1 and 1000 are: 1000 51 563 618 776 172 987 49 653 624 #### Remember above values may not be same for you as they will be random. |

Java 2nd method:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | /** * Generate Random Number within Range using Java * @author Deepak Verma * */ import java.util.Random; public class Generate_Random_Number_within_Range_using_Java_Example_2 { public static void main(String args[]) { int minimum = 1; int maximum = 1000; System.out.println("Ten Random Numbers b/w 1 and 1000 are:"); //Create an object of Random class Random random = new Random(); //Generate 10 random numbers between 1 and 1000 for (int i = 0; i < 10; i++) { int randomNumber = random.nextInt((maximum - minimum) + 1) + minimum; System.out.println(randomNumber); } } } |
Output:
1 2 3 4 5 6 7 8 9 10 11 12 13 | Ten Random Numbers b/w 1 and 1000 are: 987 373 299 446 425 885 458 830 541 899 #### Remember above values may not be same for you as they will be random. |
