i tried to search in Google but can't find anything that'll match what I'm searching for. Please help me out with these. Thanks!!! and more power to us

Dude, you're doing it wrong. The numbers on a phone go like this:

The program asks for a number and keeps asking for a number until the number is odd.
After which the program creates the first line with random numbers with the middle one being a 1
and all of the other numbers are randomly selected.

Code:

import java.util.*;

public class MagicSquare 
{
	
	
	public static void main(String[]args)
	{
		String magicSquare = "";
		int size;
		int[] arrayNumbers = {2,3,4,5,6,7,8,9};
		Random randomNumber = new Random();
		Scanner input = new Scanner(System.in);
		
		do
		{
		System.out.printf("Enter an odd number: ");
		size = input.nextInt();
		}while(size < 0 && (size%2)==0);
		
		System.out.printf("Creating a magic square with the size of %d\n", size);
		
		//create first line before the 1
		for(int i = 0;i<size/2;i++)
		{
			magicSquare += arrayNumbers[randomNumber.nextInt(arrayNumbers.length)];
		}
		
			magicSquare += "1"; 
			
		for(int i = 0;i<size/2; i++)
		{
			magicSquare += arrayNumbers[randomNumber.nextInt(arrayNumbers.length)];
		}
			magicSquare += "\n";
			
		//first line created
			
			
		//create the rest of the lines
			for(int i = 0; i < size-1;i++)
			{
				for(int j = 0;j<size;j++)
				{
					magicSquare += arrayNumbers[randomNumber.nextInt(arrayNumbers.length)];
				}
				magicSquare += "\n";
			}
				
			System.out.printf("The magic square has been completed:\n%s",magicSquare);
	}	
}
