Question

Write a java code to do the following:

1- constant number for 1000 number that is the size of the array
2- sample size will be 50
3- so i want the program to get a random number for example.
1000/50 = 20

The random will start to see from 1 to 21 then to 41, 61, 91 and so on

The 20 is the gap between the numbers.

All the number should be consistent please

Answer 1

source code:

import java.util.Random;
public class randomgenerate{

     public static void main(String []args){
        Random rand = new Random();
        int[] arr = new int[50];    //sample size 50
        int x=1000/50;              //for generating gap between two random numbers
        int y,z=1;
      
        for(int i=0;i<50;i++)
        {
            y=rand.nextInt(x+1);      //generate random number and then it store to y
            y=( y%x + 1 )+z;        //now value of y will in range like(1,21),(22,41),(42,61)....
            arr[i]=y;               //store the number to array
            z=z+x;                  //increment value of z for generate numbers in given range
        }
      
        //printing the all the value of random numbers which is already stored in array
    for(int i=0;i<50;i++)
    {
        System.out.print(arr[i]+" ");
  
    }
    }
}

description::

• first i have create array of size 50 for storing random numbers which is consistent and in the given range
• then i have generate random numbers which will be in given range and store in the array
• at last i have just print whole array
