Question

Write a program for the following.

Create an array RW[ ] of type int and size 8 and fill it with variables. Create another array EW[ ] that contains the even elements of RW[ ] in front followed by the odd elements.

For example:

Input	RW[ ]	31	45	62	87	54	29	83	44
Output	EW[ ]	62	54	44	31	45	87	29	83

import java.util.Scanner;
public class RearrangeEvenOdd 
{
    public static void main(String[] args) 
    {
        Scanner sc = new Scanner(System.in);        
        int RW[] = new int[8];
        int EW[] = new int[8];        
        System.out.println("Enter 8 integers for array RW:");
        for (int j = 0; j < RW.length; j++) 
        {
            RW[j] = sc.nextInt();
        }
                int left = 0;
        int right = RW.length        
        for (int j = 0; j < RW.length; j++)
        {
            if (RW[j] % 2 == 0) 
           {
                EW[left] = RW[j];
                left++; 
            } else {
                EW[right] = RW[j];
                right--;  
            }
        }
        System.out.print("EW[ ]\t");
        for (int j = 0; j < EW.length; j++) 
        {
            System.out.print(EW[j] + "\t");
        }        
        sc.close();
    }
