要像这样格式化和显示日期,例如YearMonth,您需要设置模式:
uuuuMM
首先,设置一个LocalDate:
LocalDate localDate = LocalDate.now();
现在格式化并显示日期为'201904':
localDate.format(DateTimeFormatter.ofPattern("uuuuMM"))
import java.time.LocalDate; import java.time.format.DateTimeFormatter; public class Demo { public static void main(String[] args) { LocalDate localDate = LocalDate.now(); System.out.println("Date = "+localDate); System.out.println("Date (Year and Month) = "+localDate.format(DateTimeFormatter.ofPattern("uuuuMM"))); } }
输出结果
Date = 2019-04-19 Date (Year and Month) = 201904
