This does the trick but may not be the easiest:
这可以解决问题，但可能不是最简单的：
import java.util.*;
import java.text.*;
class Test {
public static void main (String[] args) {
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");
Date date = new Date();
System.out.println(dateFormat.format(date));
}
}

Just use: SimpleDateFormat
只需使用：SimpleDateFormat
// Create an instance of SimpleDateFormat used for formatting
// the string representation of date (month/day/year)
DateFormat df = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
// Get the date today using Calendar object.
Date today = Calendar.getInstance().getTime();
// Using DateFormat format method we can create a string
// representation of a date with the defined format.
String reportDate = df.format(today);
// Print what date is today!
System.out.println("Report Date: " + reportDate);

is that what you are looking for?
这就是你要找的吗？
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd");
System.out.println(LocalDate.now().format(formatter));
