日历 getInstance 获取和设置不起作用

Question

我想更改安卓日历时间。 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));

但没有发生任何变化

get 方法返回我默认的仿真时间

谁能帮助我？ 谢谢！

 Calendar c = Calendar.getInstance();
    c.set(Calendar.HOUR_OF_DAY, 10);
    c.set(Calendar.MINUTE, 10);
    c.set(Calendar.SECOND, 10);
    System.out.println("h : " + c.get(Calendar.HOUR_OF_DAY));
    System.out.println("m :" + c.get(Calendar.MINUTE));
    System.out.println("s :" + c.get(Calendar.SECOND));
