Here is my improved code. However I do currently have one issue. When I print my alternating symbols method, its prints the board twice. I am not sure why. Earlier I attempted to put that portion of the method in a while loop using a count to try and end it but that did not work out for me. Any more help would be greatly appreciated.

Thanks.

import java.util.Scanner;

public class Board 
{
	static int i;				//variable to set rows and column equal to the same
	static String sym;			//symbol used to set entire array to same symbol
	static String sym1;			//symbol used with sym2 to alternate and create checkboard
	static String sym2;			//symbol used with sym1 to create checkerboard
	static String sym3;			//used in the insertSymbol method
	static int r;				//used in insertSymbol method. Represents row
	static int c;				//used in the insertSymbol method. represents column.
	static Scanner in;			//scanner variable called in
	static String [][] BoardArray;	//declaring a string array called BoardArray
	static int test;
	static int boardCount = 0;

public void setSize()			//method to set the size of the array
	{
		System.out.println("Please enter a whole number to represent" +
		" the length and width of your board.");
		i=in.nextInt();
		BoardArray= new String[i][i];
	}

public void placeSymbol()		//method to place a symbol in every cell of the array
	{
		
		System.out.println("Please enter any character and" +
		" this character will fill the board.");
		sym = in.next();
		for(int column = 0; column <i; column++)
			for(int row = 0; row<i; row++)
				BoardArray[row][column]=sym;
	}

public void alternateSymbols()		//method to place two symbols alternating in the array
	{
		System.out.println("Please enter a Character.");
		sym1=in.next();
		System.out.println("Please enter another character.");
		sym2=in.next();
		
		for (int row = 0; row < i; row++) 
		{
			for (int col = 0; col < i; col++) 
			{
				test = row + col; // adds each position...
				if (test % 2 == 0) 
				{
					BoardArray[row][col] = sym1; // add character at even array position
				}
				else 
				{
					BoardArray[row][col] = sym2; // add character at odd array position
				}
				System.out.print(" " + BoardArray[row][col]); // Prints my alternate output
			}
			System.out.println(" ");
		}
	}
	public void insertSymbol()		//method to insert a specific symbol into a specific address of the array
	{
		System.out.println("Please enter the row number you"+
		" want to insert at.");
		r=in.nextInt();
		r--;
		System.out.println("Please enter the column number"+
		" you want to insert at.");
		c=in.nextInt();
		c--;
		System.out.println("Please enter the character you want"+
		" inserted at that address.");
		sym3=in.next();
		BoardArray[r][c]=sym3;
		      
      
	}

public void printBoard()
	{
		for(int i = 0; i < BoardArray.length; i++) 
		{
			for(int j = 0; j < BoardArray.length; j++) 
			{
				System.out.print(" " + BoardArray[i][j]);
			}
			System.out.println();
		}
   }

public static void main(String[] args) 
	{
		in = new Scanner(System.in);
		boolean done = false;
		Board someBoard=new Board();
		
		System.out.println("Follow the instructions \n");
		
		while (done!=true)
		{
			
			someBoard.setSize();			// Sets size of board.
			someBoard.placeSymbol();	// Sets character of board.
			someBoard.printBoard();		// Prints single character board.
			
			someBoard.alternateSymbols(); 	// Places alternating symbols on board.
			
			someBoard.printBoard(); 	// Prints alternating symbol board.
			someBoard.insertSymbol();	// Gets symbol, row, and col to insert into board.
			someBoard.printBoard();		// Prints new selected symbol board.
			done = true;
		}
	}
