Use a SimpleDateFormat to parse the date and then print it out with a SimpleDateFormat withe the desired format.
使用 SimpleDateFormat 解析日期，然后使用具有所需格式的 SimpleDateFormat 将其打印出来。
Here's some code:
这是一些代码：
SimpleDateFormat format1 = new SimpleDateFormat("MM/dd/yyyy");
SimpleDateFormat format2 = new SimpleDateFormat("dd-MMM-yy");
Date date = format1.parse("05/01/1999");
System.out.println(format2.format(date));
Output:

You should use java.timeclasses with Java 8 and later. To use java.time, add:
您应该在 Java 8 及更高版本中使用java.time类。要使用java.time，请添加：
import java.time.* ;
Below is an example, how you can format date.
下面是一个示例，说明如何格式化日期。
DateTimeFormatter format = DateTimeFormatter.ofPattern("dd-MMM-yyyy");
String date = "15-Oct-2018";
LocalDate localDate = LocalDate.parse(date, formatter);
System.out.println(localDate);
System.out.println(formatter.format(localDate));

final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy");
LocalDate localDate = LocalDate.now();
System.out.println("Formatted Date: " + formatter.format(localDate));
Java 8 LocalDate
Java 8 本地日期
