Java中的 OffsetTime getLong() 方法及示例

Java中OffsetTime类的getLong()方法从这个时间获取参数中指定字段的值作为long。

句法 :

public long getLong(TemporalField field)

参数:此方法接受单个参数字段,该字段指定要获取的字段,而不是 null。
返回值:它返回字段的值。
错误和异常:程序返回三个异常,描述如下:

  • UnsupportedTemporalTypeException:如果该字段不被支持或值的范围超过一个long,则抛出它。
  • DateTimeException:如果无法获取该字段的值或该值超出该字段的有效值范围,则抛出该异常。
  • ArithmeticException:如果发生数值溢出则抛出

下面的程序说明了 getLong() 方法:
程序 1:

Java
// Java program to demonstrate the getLong() method
 
import java.time.OffsetTime;
import java.time.temporal.ChronoField;
 
public class GFG {
    public static void main(String[] args)
    {
        // Parses the time
        OffsetTime time = OffsetTime.parse("11:10:10+11:00");
        System.out.println("Gets the long time: "
               + time.getLong(ChronoField.CLOCK_HOUR_OF_DAY));
    }
}


Java
// Java program to demonstrate the getLong() method
// Exceptions
 
import java.time.OffsetTime;
import java.time.temporal.ChronoField;
 
public class GFG {
    public static void main(String[] args)
    {
 
        try {
 
            // Parses the time
            OffsetTime time = OffsetTime.parse("11:10:10+11:00");
            System.out.println("Gets the long time: "
                   + time.getLong(ChronoField.CLOCK_HOUR_OF_DAY));
        }
        catch (Exception e) {
            System.out.println("Exception: " + e);
        }
    }
}


输出:
Gets the long time: 11

方案二

Java

// Java program to demonstrate the getLong() method
// Exceptions
 
import java.time.OffsetTime;
import java.time.temporal.ChronoField;
 
public class GFG {
    public static void main(String[] args)
    {
 
        try {
 
            // Parses the time
            OffsetTime time = OffsetTime.parse("11:10:10+11:00");
            System.out.println("Gets the long time: "
                   + time.getLong(ChronoField.CLOCK_HOUR_OF_DAY));
        }
        catch (Exception e) {
            System.out.println("Exception: " + e);
        }
    }
}
输出:
Gets the long time: 11
