java - Android - 2 小时后获取时间

Question

在我的 Android 应用中。我每 2 小时运行一次任务。如何检查时间是否超过 2 小时。

我尝试使用它，但它说已弃用

Date date = new Date();
date.setHours(date.getHours() + 2);

我会很感激关于如何实现它的见解？

Calendar current_time = Calendar.getInstance ();
current_time.add(Calendar.YEAR, 0);
current_time.add(Calendar.DAY_OF_YEAR, 0);
current_time.set(Calendar.HOUR_OF_DAY, 
//Subtract 2 hours       
current_time.get(Calendar.HOUR_OF_DAY)-2);
current_time.set(Calendar.MINUTE, 0);
current_time.set(Calendar.SECOND, 0);

Calendar given_time = Calendar.getInstance ();
given_time.set(Calendar.YEAR, syear);
//Give the day sDay and hour shour
given_time.set(Calendar.DAY_OF_YEAR, sday);
given_time.set(Calendar.HOUR_OF_DAY, shour);
given_time.set(Calendar.MINUTE, 0 );
given_time.set(Calendar.SECOND, 0);

Date current_calendar = current_time.getTime();
Date given_calendar = given_time.getTime();

System.out.println("Current Calendar "+ current_calendar);
System.out.println("Given Calendar "+ given_calendar);

boolean v = current_calendar.after(given_calendar); 

if(v){

    return true;

}
