IOTester.java
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class I18NTester {
public static void main(String[] args) throws ParseException {
String pattern = "dd-MM-yy";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);
Date date = new Date();
System.out.println(simpleDateFormat.format(date));
pattern = "MM-dd-yyyy";
simpleDateFormat = new SimpleDateFormat(pattern);
System.out.println(simpleDateFormat.format(date));
pattern = "yyyy-MM-dd HH:mm:ss";
simpleDateFormat = new SimpleDateFormat(pattern);
System.out.println(simpleDateFormat.format(date));
pattern = "EEEEE MMMMM yyyy HH:mm:ss.SSSZ";
simpleDateFormat = new SimpleDateFormat(pattern);
System.out.println(simpleDateFormat.format(date));
}
}
它将打印以下结果。
