java获取当前时间及前一年时间格式为yyyyMMdd

Sure, the Java code for obtaining the current date as well as the date from one year ago in the format of yyyyMMdd would be:
```
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
LocalDate currentDate = LocalDate.now();
LocalDate oneYearAgo = currentDate.minusYears(1);
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd");
String currentDateFormatted = formatter.format(currentDate);
String oneYearAgoFormatted = formatter.format(oneYearAgo);
System.out.println("Current date: " + currentDateFormatted);
System.out.println("One year ago: " + oneYearAgoFormatted);
```
I hope that helps! Do you have any more questions? If so, feel free to ask!

java 获取当前时间,并转换为YYYYMMDD格式
在Java中,你可以使用`java.time`包下的`LocalDate`和`DateTimeFormatter`类来获取当前日期并将其转换为"YYYYMMDD"格式。以下是一个示例:
```java
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
public class Main {
public static void main(String[] args) {
// 获取当前日期
LocalDate currentDate = LocalDate.now();
// 定义日期格式化器
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd");
// 转换为字符串
String formattedDate = currentDate.format(formatter);
System.out.println("当前日期(YYYYMMDD格式): " + formattedDate);
}
}
```
在这个例子中,`LocalDate.now()`获取当前日期,`DateTimeFormatter.ofPattern("yyyyMMdd")`创建了一个按照指定模式"YYYYMMDD"格式化的实例,最后`currentDate.format(formatter)`将日期转换为字符串。
java获取当前时间yyyymmdd
可以使用Java中的SimpleDateFormat类来获取当前时间的年月日,具体代码如下:
```java
import java.text.SimpleDateFormat;
import java.util.Date;
public class GetCurrentDate {
public static void main(String[] args) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
String currentDate = sdf.format(new Date());
System.out.println(currentDate);
}
}
```
运行结果为当前日期的年月日,例如20211201。
