Question

Write a complete program called EvenNums that uses a

method to create arrays of even numbers starting 1 of the given length:

public static int[] getEvenNums(int length) {}

EX:

int[] nums = getEvenNumbers(6);

System.out.println(Arrays.toString(nums));

expected output:

[2, 4, 6, 8, 10, 12]

Answer 1

The code in java is given below.

import java.util.Arrays;
import java.util.Scanner;

public class EvenNums
{
    public static int[] getEvenNumbers(int length)
    {
        int[] nums=new int[length];
        int j=2;
        for(int i=0;i<length;i++)
        {
            nums[i]=j;
            j=j+2;
        }
        return nums;
    }

    public static void main(String[] args)
    {
        Scanner sc=new Scanner(System.in);
        int length;
        System.out.print("Enter the length of the array: ");
        length=sc.nextInt();
        int[] nums=getEvenNumbers(length);
        System.out.println("The output array is");
        System.out.println(Arrays.toString(nums));
    }
}
