Java中的 YearMonth plusYears() 方法及示例
Java中YearMonth 类的plusYears()方法用于返回此 YearMonth 的副本,其中添加了指定的年数。
句法:
public YearMonth plusYears(long yearsToAdd)
参数:此方法接受yearsToAdd作为参数,表示要添加到当前 YearMonth 对象的年份。它可能是负面的。
返回值:它根据添加的年份返回基于此年月的YearMonth 。
异常:如果结果超出支持的范围,此方法将引发DateTimeException 。
下面的程序说明了Java中 YearMonth 的 plusYears() 方法:
方案一:
// Java program to demonstrate
// YearMonth.plusYears() method
import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// Create YearMonth object
YearMonth yearmonth
= YearMonth.parse("2020-05");
// Apply plusYears() method
// of YearMonth class
YearMonth result
= yearmonth.plusYears(5);
// It will add 5 years into May 2020
// So it will be May 2025
// print results
System.out.println(
"Modified YearMonth: "
+ result);
}
}
输出:
Modified YearMonth: 2025-05
方案二:
// Java program to demonstrate
// YearMonth.plusYears() method
import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// Create YearMonth object
YearMonth yearmonth
= YearMonth.of(2019, 10);
// It is October 2019
// apply plusYears() method
// of YearMonth class
YearMonth result
= yearmonth.plusYears(10);
// YearMonth will become October 2029
// print only modified year
System.out.println(
"Modified Year: "
+ result.get(ChronoField.YEAR));
}
}
输出:
Modified Year: 2029
