Java中的 MinguoChronology eraOf() 方法示例

Java.time.chrono.MinguoChronology类的eraOf()方法用于通过数值检索MinguoEra。

句法：

public MinguoEra eraOf(int eraValue)

参数：此方法将eraValue整数作为将为其生成MinguoEra的参数。

返回值：该方法通过数值返回民国时代。

以下是说明eraOf()方法的示例：

示例 1：

// Java program to demonstrate
// eraOf() 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 LocalDate
            MinguoChronology crono
                = hidate.getChronology();
  
            // getting MinguoEra for the
            // given integer value
            // by using eraOf() method
            MinguoEra era = crono.eraOf(0);
  
            // display the result
            System.out.println(
                "MinguoEra is: "
                + era);
        }
        catch (DateTimeException e) {
            System.out.println(
                "MinguoEra is invalid");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}

输出：

MinguoEra is: BEFORE_ROC

示例 2：

// Java program to demonstrate
// eraOf() 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 LocalDate
            MinguoChronology crono
                = hidate.getChronology();
  
            // getting MinguoEra for the
            // given integer value
            // by using eraOf() method
            MinguoEra era = crono.eraOf(1);
  
            // display the result
            System.out.println(
                "MinguoEra is: "
                + era);
        }
        catch (DateTimeException e) {
            System.out.println(
                "MinguoEra is invalid");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}

输出：

MinguoEra is: ROC
