An example of an algorithm that determines whether the date is within one year

In the project, you need to determine whether the incoming date is within the next year. Baidu found no good way online, and wrote it to facilitate yourself and others:

int datecompareAfter = compareDate(new Date(), date);
	int daecompareBefore = compareDate(date, getOneYear());

	if (datecompareAfter == -1 &amp;&amp; daecompareBefore == -1) {

	  //If it is not within one year, a prompt will pop up
	} else {
		//Logistics done within one year	}
	
	
	// Compare the timepublic int compareDate(Date d1, Date d2) {
		if (() &gt; ()) {
return 1;
		} else if (() &lt; ()) {
return -1;
		} else {// Equalreturn 0;
		}
	}

	//The current time plus 1 yearpublic Date getOneYear() {
		Calendar c = ();
		(, 1);
		return ();
}

The above example of the algorithm for determining whether the date is within one year of Android is all the content I have shared with you. I hope you can give you a reference and I hope you can support me more.
