原文:https://www . geesforgeks . org/hijrahdate-mins long-tempalalunit-method-in-Java-with-example/
Java . time . chrono . HijrahDate类的减()方法用于在从当前 hijrah date 中减去一定数量的时态访问器单位后获取 hijrah date。
语法:
public HijrahDate minus(long amountToSubtract,
TemporalUnit unit)
参数:该方法以下列参数为参数:
- Amount to Subtract: is the time unit value to be subtracted from the current Hijra date.
- Unit: is an object of time unit or hour unit.
返回值:此方法在当前回历日期减去一个时间存取器单位后，返回回历日期。
以下是举例说明减去()方法的例子:
例 1:
爪哇
// Java program to demonstrate minus() method
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] argv)
{
try {
// Creating and initializing
// HijrahDate Object
HijrahDate hidate = HijrahDate.now();
// Display the result
System.out.println("old hijrah date: "
+ hidate);
// Subtracting hijrah date
// by using minus() method
HijrahDate newdate
= hidate.minus(
22, ChronoUnit.DAYS);
// Display the result
System.out.println("new hijrah date: "
+ newdate);
}
catch (DateTimeException e) {
System.out.println("passed parameter can"
+ " not form a date");
System.out.println("Exception thrown: "
+ e);
}
}
}
输出:
old hijrah date: Hijrah-umalqura AH 1441-06-25
new hijrah date: Hijrah-umalqura AH 1441-06-03
例二:
爪哇
// Java program to demonstrate minus() method
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] argv)
{
try {
// Dreating and initializing
// HijrahDate Object
HijrahDate hidate
= HijrahDate.now();
// Display the result
System.out.println("old hijrah date: "
+ hidate);
// Subtracting hijrah date
// by using minus() method
HijrahDate newdate
= hidate.minus(
4, ChronoUnit.DECADES);
// Display the result
System.out.println("new hijrah date: "
+ newdate);
}
catch (DateTimeException e) {
System.out.println("passed parameter can"
+ " not form a date");
System.out.println("Exception thrown: "
+ e);
}
}
}
输出:
old hijrah date: Hijrah-umalqura AH 1441-06-25
new hijrah date: Hijrah-umalqura AH 1401-06-25
