怎么从键盘中输入二维数组，编程环境是Jcreator，二维数组为三行四列。我是新手不要弄太难的代码哟，看不懂的！

import javax.swing.JOptionPane;
 
 
public class print_jinzita {
    public static void main(String[] args){
        int [] [] array = new int[3][4];
        for(int row = 0;row <= array.length;row++)
            for(int column = 0; column <array[0].length; column++){
                array[row][column] = Integer.parseInt(JOptionPane.showInputDialog("输入array["+row+"]["+column+"]"));
            }
         
         
    }
      
 
}
