How do i print a table with multidimensional array.

[Dmitri Makovetskiy]

Here is my array:

     pieces[2][1]=new Pawn("Bpn1");
			   pieces[2][2]=new Pawn("Bpn2");
			   pieces[2][3]=new Pawn("Bpn3");
			   pieces[2][4]=new Pawn("Bpn4");
			   pieces[2][5]=new Pawn("Bpn5");
			   pieces[2][6]=new Pawn("Bpn6");
			   pieces[2][7]=new Pawn("Bpn7");
			   pieces[2][8]=new Pawn("Bpn8");
			   					  
			      pieces [1][1]=new Rook("BR1");
				  pieces [1][2]=new Knight("BN1");
				  pieces [1][3]=new Bishop("BB1");
				  pieces [1][4]=new King("BKing");
				  pieces [1][5]=new Queen("BQueen");;
				  pieces [1][6]=new Bishop("BB2");
				  pieces [1][7]=new Knight("BN2");
				  pieces [1][8]=new Rook("BR2");		  
		  
				   pieces[7][1]=new Pawn("Wpn1");
				   pieces[7][2]=new Pawn("Wpn2");
				   pieces[7][3]=new Pawn("Bpn3");
				   pieces[7][4]=new Pawn("Wpn4");
				   pieces[7][5]=new Pawn("Wpn5");
				   pieces[7][6]=new Pawn("Wpn6");
				   pieces[7][7]=new Pawn("Wpn7");
				   pieces[7][8]=new Pawn("Wpn8");
				   	   	  
				      pieces [8][1]=new Rook("WR1");
					  pieces [8][2]=new Knight("WN1");
					  pieces [8][3]=new Bishop("WB1");
					  pieces [8][4]=new King("WKing");
					  pieces [8][5]=new Queen("WQueen");;
					  pieces [8][6]=new Bishop("WB2");
					  pieces [8][7]=new Knight("WN2");
					  pieces [8][8]=new Rook("WR2");
					  
					  
			         
					  

  String[] drawNull=new String[6];
					    drawNull[0]="                  ";			  
					 	drawNull[1]="__________________";
						drawNull[2]="|                |";
						drawNull[3]="|                |";
						drawNull[4]="|                |";
						drawNull[5]="|_______________ |";
				
						  
					   

board(pieces,drawNull,4);

board(pieces,drawNull,3);


i created a method to print one column:

  static void board(ChessPiece[][] pieces, String[] drawNull, int x){					
	for (int a = 1; a < pieces.length; a++) {
		if(pieces [a][x]!=null){
		pieces [a][x].print();
		
		System.out.print("_______________________");
		}
		else{

			for(int m=0;m<drawNull.length;m++)
		    	 System.out.println(drawNull[m]);
			System.out.print("__________________");
		}
		
	 }
	
	
	}  

how can i print one column next to another?

I'm not really sure what you're doing with printing lines there ... "_________" for example ... but generally, you'd want to have two nested for loops. The idea is: for each rank, print out the pieces at each file in that rank, then print a new line, then go to then next rank. (Rank = row, file = column.)

i solved the problem

here is my algorithm

  
      	String rows=" abcdefgh";
      	int num1=9;

      		for (int i = 0; i < array.length; i++) {
      	
      			
      		for (int j = 1; j < array[i].length; j++) {
      			if(i==0){
      			System.out.print("   "+rows.charAt(j)+"    ");
      			}
      			else{
      				if(i>0)
      			System.out.print(array[i][j]);
      			}
      		}	
      		if(i==0)
      		System.out.println();
              if(i>0)
      		System.out.println(num1-i);
      		}				 
          }

  

and here is my table

    
   a       b       c       d       e       f       g       h    
|Wrook||Wknight||WBishop||WKing||WQueen||WBishop||Wknight||Wrook|8
| Wpn1 || Wpn2 || Bpn3 || Wpn4 || Wpn5 || Wpn6 || Wpn7 || Wpn8 |7
| Null || Null || Null || Null || Null || Null || Null || Null |6
| Null || Null || Null || Null || Null || Null || Null || Null |5
| Null || Null || Null || Null || Null || Null || Null || Null |4
| Null || Null || Null || Null || Null || Null || Null || Null |3
| Bpn1 || Bpn2 || Bpn3 || Bpn4 || Bpn5 || Bpn6 || Bpn7 || Bpn8 |2
|Brook||Bknight||BBishop||BKing||BQueen||BBishop||Bknight||Brook|1
