Java中的 MinguoChronology prolepticYear() 方法示例
Java.time.chrono.MinguoChronology类的prolepticYear()方法用于检索特定民国时代民国系统中存在的预兆年。
句法:
public int prolepticYear(Era era,
int yearOfEra)
参数:此方法将以下参数作为参数。
- 时代:这是民国时代的对象。
- yearofEra:这是特定民国时代的年份
返回值:该方法返回特定民国时代民国系统中存在的预兆年份。
以下是说明prolepticYear()方法的示例:
示例 1:
// Java program to demonstrate
// prolepticYear() method
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating and initializing
// MinguoDate Object
MinguoDate hidate
= MinguoDate.now();
// getting MinguoChronology
// used in MinguoDate
MinguoChronology crono
= hidate.getChronology();
// getting prolepticYear for the
// given year of Era
// by using prolepticYear() method
int proyear
= crono.prolepticYear(
MinguoEra.ROC,
1444);
// display the result
System.out.println("proleptic Year is: "
+ proyear);
}
catch (DateTimeException e) {
System.out.println(
"passed parameter can"
+ " not form a date");
System.out.println(
"Exception thrown: " + e);
}
}
}
输出:
proleptic Year is: 1444
示例 2:
// Java program to demonstrate
// prolepticYear() method
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating and initializing
// MinguoDate Object
MinguoDate hidate
= MinguoDate.now();
// getting MinguoChronology
// used in MinguoDate
MinguoChronology crono
= hidate.getChronology();
// getting prolepticYear for the
// given year of Era
// by using prolepticYear() method
int proyear
= crono.prolepticYear(
MinguoEra.BEFORE_ROC,
1444);
// display the result
System.out.println("proleptic Year is: "
+ proyear);
}
catch (DateTimeException e) {
System.out.println(
"passed parameter can"
+ " not form a date");
System.out.println(
"Exception thrown: " + e);
}
}
}
输出:
proleptic Year is: -1443
