swing - Java Tic Tac Toe GUI -

the code works fine problem want 3 columns , 3 rows.. output shows 6 columns instead of 3 rows , 3 columns

here code in problem appears.. here main class:

import java.awt.event.actionevent; import java.awt.event.actionlistener;  import games.board.board; import games.board.cell; import games.board.mark;  import javax.swing.jframe; import javax.swing.swingutilities;    public class tictactoeguigame extends jframe  {  /**  * @param args  */ private board gb; private int turn; private void taketurn(cell c) {     mark curmark = (turn++ % 2 == 0)? mark.nought     : mark.cross;     gb.setcell(curmark, c.getrow(), c.getcolumn());     } private tictactoeguigame() {     gb = new board(3, 3, new actionlistener() {     public void actionperformed(actionevent ae) {     cell c = (cell) ae.getsource();     taketurn(c);     }     });     this.add(gb);     this.setdefaultcloseoperation(exit_on_close);     this.settitle("tic-tac-toe");     this.setsize(300, 300);     this.setvisible(true);     }   public static void main(string[] args) {     // todo auto-generated method stub     swingutilities.invokelater( new runnable () {         public void run() { new tictactoeguigame(); }         });  }  } 

here board class:

package games.board;  import java.awt.gridlayout; import java.awt.event.actionevent; import java.awt.event.actionlistener; import javax.swing.jpanel; import javax.swing.jframe;  public class board extends jpanel { private cell[][] cells; public board(int rows, int columns) { cells = new cell[rows][columns]; for( int r = 0; r < cells[0].length; r++ ) { (int c = 0; c < cells[1].length; c++) { cells[r][c] = new cell(r,c); } } } public board(int rows, int columns, actionlistener ah) {     cells = new cell[rows][columns];     this.setlayout(new gridlayout());     for( int r = 0; r < cells.length; r++ ) {     (int c = 0; c < cells[r].length; c++) {     cells[r][c] = new cell(r,c);     this.add(cells[r][c]);     cells[r][c].addactionlistener(ah);     }     }     } public void setcell(mark mark, int row, int column) throws illegalargumentexception { if (cells[row][column].getcontent() == mark.empty) cells[row][column].setcontent(mark); else throw new illegalargumentexception("player there!"); } public cell getcell(int row, int column) { return cells[row][column]; } public string tostring() { stringbuilder str = new stringbuilder(); for( int r = 0; r < cells.length; r++ ) { str.append("|");    (int c = 0; c < cells[r].length; c++) { switch(cells[r][c].getcontent()) { case nought:     str.append("o");     break;     case cross:     str.append("x");     break;     case yellow:     str.append("y");     break;     case red:     str.append("r");     break;     case blue:     str.append("b");     break;     case green:     str.append("g");     break;     case magenta:     str.append("m");     break;     case orange:     str.append("m");     break;     default: //empty     str.append("");     }     str.append("|");     }     str.append("\n");     }     return str.tostring();  }  } 

i want 3 columns , 3 rows.. output shows 6 columns

you need specify proper parameters gridlayout:

this.setlayout(new gridlayout(0, 3)); 

this tell grid contain 3 columns. number of rows depend on number of components add.
