Java中的 ThaiBuddhistDate minus(long, TemporalUnit) 方法

Java.time.chrono.ThaiBuddhistDate类的minus()方法用于在从当前 ThaiBuddhist 日期中减去一定数量的时间访问器单元后获取 ThaiBuddhist 日期。

句法：

public ThaiBuddhistDate minus(
           long amountToSubtract,
           TemporalUnit unit)

参数：此方法将以下参数作为参数：

• amountToSubtract：这是将从当前 ThaiBuddhist 日期中减去的时间单位的值。
• unit：时间单位或计时单位的对象。

返回值：此方法在从当前 ThaiBuddhist 日期中减去一定数量的时间访问器单元后返回 ThaiBuddhist 日期。

以下是说明minus()方法的示例：

示例 1：

Java

// 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
            // ThaiBuddhistDate Object
            ThaiBuddhistDate hidate
                = ThaiBuddhistDate.now();
 
            // Display the result
            System.out.println(
                "Old ThaiBuddhist date: "
                + hidate);
 
            // Subtracting ThaiBuddhist date
            // by using minus() method
            ThaiBuddhistDate newdate
                = hidate.minus(
                    22, ChronoUnit.DAYS);
 
            // Display the result
            System.out.println(
                "New ThaiBuddhist date: "
                + newdate);
        }
        catch (DateTimeException e) {
 
            System.out.println(
                "Passed parameter can"
                + " not form a date");
 
            System.out.println(
                "Exception thrown: "
                + e);
        }
    }
}

输出：

Old ThaiBuddhist date: ThaiBuddhist BE 2563-05-03
New ThaiBuddhist date: ThaiBuddhist BE 2563-04-11

        }
    }
}

输出：

Old ThaiBuddhist date: ThaiBuddhist BE 2563-05-03
New ThaiBuddhist date: ThaiBuddhist BE 2523-05-03
