Calendar getInstance get和set not working

Question

我想更改android日曆時間。 這是我的代碼：

 Calendar c = Calendar.getInstance(); 
    c.set(Calendar.HOUR_OF_DAY, 10); 
    c.set(Calendar.MINUTE, 10); 
    c.set(Calendar.SECOND, 10); 

...其他代碼和方法

 System.out.println("h : " + Calendar.getInstance().get(Calendar.HOUR_OF_DAY)); 
    System.out.println("m :" + Calendar.getInstance().get(Calendar.MINUTE)); 
    System.out.println("s :" + Calendar.getInstance().get(Calendar.SECOND)); 

但沒有發生變化

get方法返回我默認仿真時間

可以ENY一個幫助我？ 謝謝！
