该博客展示了一段Java代码，通过导入相关包，创建日期对象并使用DateFormat类的不同实例对日期进行格式化，最后输出不同格式的日期，如默认、短、中、长和完整格式。

import java.util.*;
import java.text.*;

public class StyleDemo {
   public static void main(String[] args) {
      Date now = new Date();

      DateFormat df = DateFormat.getDateInstance();
      DateFormat df1 = DateFormat.getDateInstance(DateFormat.SHORT);
      DateFormat df2 = DateFormat.getDateInstance(DateFormat.MEDIUM);
      DateFormat df3 = DateFormat.getDateInstance(DateFormat.LONG);
      DateFormat df4 = DateFormat.getDateInstance(DateFormat.FULL);
      String s = df.format(now);
      String s1 = df1.format(now);
      String s2 = df2.format(now);
      String s3 = df3.format(now);
      String s4 = df4.format(now);

      System.out.println("(Default) Today is " + s);
      System.out.println("(SHORT) Today is " + s1);
      System.out.println("(MEDIUM) Today is " + s2);
      System.out.println("(LONG) Today is " + s3);
      System.out.println("(FULL) Today is " + s4);
   }
}

That program output the following:

(Default) Today is Nov 8, 2000
(SHORT) Today is 11/8/00
(MEDIUM) Today is Nov 8, 2000
(LONG) Today is November 8, 2000
(FULL) Today is Wednesday, November 8, 2000
