java中get接⼝⽰例
get out of即时类的get()⽅法 (Instant Class get() method)
get() method is available in java.time package.
get() method
get()⽅法在java.time包中可⽤。
get()⽅法
get() method is used to get the value of the given field from this Instant object.
get() method
get()⽅法⽤于从此Instant对象获取给定字段的值。
get()⽅法
get() method is a non-static method, it is accessible with the class object only and if we try to access the method with get() method
the class name then we will get an error.
get()⽅法是⼀个⾮静态⽅法，只能通过类对象访问，如果尝试使⽤类名称访问该⽅法，则会收到错误消息。
get()⽅法
get() method may throw an exception at the time of returning value for the given field.
get() method
get()⽅法可能会引发异常。
在返回给定字段的值时， get()⽅法
DateTimeException: This exception may throw when the given field couldn’t be generated.DateTimeException
DateTimeException DateTimeException
：当⽆法⽣成给定字段时，可能引发此异常。
UnsupportedTemporalTypeException: This exception may throw when the given field is
UnsupportedTemporalTypeException
UnsupportedTemporalTypeException ：当不⽀持给定字段时，可能引发此异常。
unsupported.UnsupportedTemporalTypeException
ArithmeticException: This exception may throw when the calculated result exceeds the
ArithmeticException
ArithmeticException ：当计算结果超出限制时，可能引发此异常。
limit.ArithmeticException
Syntax:
句法：
public int get(TemporalField t_field);
Parameter(s):
参数：
TemporalField t_field – represents the temporal field of the returned value.
TemporalField t_field –表⽰返回值的时间字段。
Return value:
返回值：
The return type of this method is int, it returns the value for the given temporal field from this Instant.
此⽅法的返回类型为int ，它从此Instant返回给定时间字段的值。
Example:
例：
// Java program to demonstrate the example
// of get(TemporalField t_field) method
// of Instant
import java.time.*;
import poral.*;
public class GetOfInstant {
public static void main(String args[]) {
// Instantiates two Instant
Instant ins1 = Instant.parse("2006-04-03T05:10:15.120Z");
Instant ins2 = Instant.parse("2007-06-05T10:20:30.20Z");
/
/ Display ins1,ins2
System.out.println("Instant ins1 and ins2: ");
System.out.println("ins1: " + ins1);
System.out.println("ins2: " + ins2);
System.out.println();
// Here, this method gets the value of the
// given field from this
// here the MICRO_OF_SECOND field value
// will be returned from this Instant ins1
int get_val = (ChronoField.MICRO_OF_SECOND);
// Display get_val
System.out.println("(ChronoField.MICRO_OF_SECOND): " + get_val);
// Here, this method gets the value of the
// given field from this
// here the MILLI_OF_SECOND field value
// will be returned from this Instant ins2
get_val = (ChronoField.MILLI_OF_SECOND);
// Display get_val
System.out.println("(ChronoField.MILLI_OF_SECOND): " + get_val); }
}
Output
输出量
Instant ins1 and ins2:
ins1: 2006-04-03T05:10:15.120Z
ins2: 2007-06-05T10:20:30.200Z
<(ChronoField.MICRO_OF_SECOND): 120000
<(ChronoField.MILLI_OF_SECOND): 200
