如何用相同大小的网格绘制画布?问题:http ://tinypic.com/r/idvc0j/5 代码绘制了最后一个单元格,其大小与其他单元格不平行。我必须在paint() 方法中做些什么改变?

public class Grid extends Canvas{
Cell[][] maze;
int rows;
int cols;
Grid(int rows, int cols) {
this.rows = rows;
this.cols = cols;
maze = new Cell[rows][cols];
}
public static void main(String[] args){
JFrame f = new JFrame("Sample");
Grid x = new Grid(25,25);
f.add(x);
f.pack();
f.setVisible(true);
f.setSize(600,600);
f.setResizable(false);
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

int htOfRow = height / (rows);
for (k = 0; k < rows; k++)
g.drawLine(0, k * htOfRow , width, k * htOfRow );
int wdOfRow = width / (cols);
for (k = 0; k < cols; k++)
g.drawLine(k*wdOfRow , 0, k*wdOfRow , height);
}
}
