原文:https://www . geeksforgeeks . org/Japanese 年表-java 中的 eraof-method-with-example/
Java . time . chrono . Japanese 年表类的 eraOf() 方法用于通过使用数值来检索 JapaneseEra。
语法:
public JapaneseEra eraOf(int eraValue)
参数:该方法将整数值作为将要生成日本种子的参数。
返回值:该方法使用数值返回日本时代。
以下是举例说明 eraOf() 方法的例子:
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
// JapaneseDate Object
JapaneseDate hidate
= JapaneseDate.now();
// getting JapaneseChronology
// used in LocalDate
JapaneseChronology crono
= hidate.getChronology();
// getting JapaneseEra for the
// given integer value
// by using eraOf() method
JapaneseEra era = crono.eraOf(0);
// display the result
System.out.println(
"JapaneseEra is: "
+ era);
}
catch (DateTimeException e) {
System.out.println(
"JapaneseEra is invalid");
System.out.println(
"Exception thrown: " + e);
}
}
}
输出:
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
// JapaneseDate Object
JapaneseDate hidate
= JapaneseDate.now();
// getting JapaneseChronology
// used in LocalDate
JapaneseChronology crono
= hidate.getChronology();
// getting JapaneseEra for the
// given integer value
// by using eraOf() method
JapaneseEra era = crono.eraOf(2);
// display the result
System.out.println("JapaneseEra is: "
+ era);
}
catch (DateTimeException e) {
System.out.println(
"JapaneseEra is invalid");
System.out.println(
"Exception thrown: " + e);
}
}
}
