Trying to print my board to output.

[Edward Strife]

I am trying to print the board to output after each change. The first change sets the entire board to one symbol. The second change sets the board to alternating symbols. I need the printBoard() method to only print the board, not modify it.

Any help would be greatly appreciated.

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 [][] Board;	//declaring a string array called Board
	
	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();
		Board= 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++)
				Board[row][column]=sym;
	}
	
	public void placeSymbols()		//method to place two symbols alternating in the array
	{
		int test;
		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; 
					if (test % 2 == 0) 
					{
						Board[row][col] = sym1; // add character at even array position
					}
					else 
					{
						Board[row][col] = sym2; // add character at odd array position
					}
				}
			}
	}
	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();
		System.out.println("Please enter the column number"+
			"you want to insert at.");
		c=in.nextInt();
		System.out.println("Please enter the character you want"+
			"inserted at that address.");
		sym3=in.next();
		Board[r][c]=sym3;
	}
	
	public void printBoard()
	{
		//Board someBoard=new Board();
		/*String output = "";
		for (int row = 0; row < i; row++) {
            for (int col = 0; col < i; col++) {
                output += sym;
            }
            output += "\n";
        }*/
        //someBoard.Board();
		  System.out.println(Board);
    
	}
	
	 public static void main(String[] args) 
    {
    	//int action;					//variable action used in switch staement
    	in = new Scanner(System.in);
    	boolean done = false;
    	Board someBoard=new Board();
    	
    	System.out.println("Follow the instructions \n");
    	
		while (done!=true)
		{
		someBoard.printBoard();
		someBoard.setSize();
		someBoard.placeSymbol();
		someBoard.printBoard();
		
		
		someBoard.placeSymbols();
		
		
		someBoard.insertSymbol();
		
		
		someBoard.printBoard();
		done = true;
		
    	}
    	
    	
    }
}

The method printBoard() should print the output value rather than the object Board.

System.out.println(output);

Actually, there's nothing particularly wrong with doing it that way...
@Edward: ...providing you implement a toString() method for your Board.

I'm puzzled. Why did you comment out that loop? It looks more like what you want to do.

Agree... But he also try to create a new instance of Board in the printMethod(). So thought he might understand printing output better
