如何将不同的日期字符串解析为LocalDate/Year？

import java.time.LocalDate;
import java.time.format.DateTimeFormatter;

public class DateParsingExample {
    public static void main(String[] args) {
        // 创建DateTimeFormatter对象
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");

        // 解析日期字符串为LocalDate对象
        String dateStr1 = "2022-01-01";
        LocalDate date1 = LocalDate.parse(dateStr1, formatter);
        System.out.println("解析后的日期1: " + date1);

        String dateStr2 = "2022-12-31";
        LocalDate date2 = LocalDate.parse(dateStr2, formatter);
        System.out.println("解析后的日期2: " + date2);
    }
}

解析后的日期1: 2022-01-01
解析后的日期2: 2022-12-31

import java.time.LocalDate;
import java.time.Year;
import java.time.format.DateTimeFormatter;

public class YearParsingExample {
    public static void main(String[] args) {
        // 创建DateTimeFormatter对象
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");

        // 解析日期字符串为LocalDate对象
        String dateStr = "2022-01-01";
        LocalDate date = LocalDate.parse(dateStr, formatter);
        
        // 转换为Year对象
        Year year = Year.from(date);
        System.out.println("解析后的年份: " + year);
    }
}

解析后的年份: 2022
