汉诺塔问题就是：有ABC三根柱子，A柱子上从上到下摞了很多体积依次递增的圆盘，如果将圆盘从A移动到C柱子，且依然保持从上到下依次递增。

class Hanio{
	public void moveOne(int n, String init, String desti){    //只有一个盘子的情况
		System.out.println(" move:"+n+" from "+init+" to "+desti);
	}
	public void move(int n, String init, String temp, String desti){
		if(n <= 0){
			System.out.println("number error");
			return;
		}
		else if(n == 1){
			moveOne(n,init,desti);
		}else{
			move(n-1, init, desti, temp);//首先将上面的（n-1）个盘子从init杆借助desti杆移至temp杆  
			moveOne(n, init, desti);     //然后将编号为n的盘子从init杆移至desti杆  
			move(n-1, temp, init, desti);//最后将上面的（n-1）个盘子从temp杆借助init杆移至desti杆   
		}
	}
}
class HanioApp{
	public static void main(String args[]){
		Hanio hanio = new Hanio();
		hanio.move(3, "A", "B", "C");
	}
}

运行结果：

 move:1 from A to C
 move:2 from A to B
 move:1 from C to B
 move:3 from A to C
 move:1 from B to A
 move:2 from B to C
 move:1 from A to C
