日历getInstance获取并设置不起作用

Question

我想改变android日历时间。 这是我的代码：

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

......其他代码和方法

        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));

但没有发生变化

get方法返回默认仿真时间

能帮助我一个人吗？ 谢谢！
