// Important points about Date

// Date is no longer the class Java recommends for storing and

// manipulating date and time. Most of methods in Date are deprecated.

// Use Calendar class instead.

// Date internally represents date-time as number of milliseconds (a

// long value) since 1st Jan 1970.

// Creating Date Object

Date now = new Date();

System.out.println(now.getTime());

// Manipulating Date Object

Date date = new Date();

// Increase time by 6 hrs

date.setTime(date.getTime() + 6 * 60 * 60 * 1000);

System.out.println(date);

// Decrease time by 6 hrs

date = new Date();

date.setTime(date.getTime() - 6 * 60 * 60 * 1000);

System.out.println(date);

// Formatting Dates

System.out.println(DateFormat.getInstance().format(date));// 10/16/12

// 5:18 AM

// Formatting Dates with a locale

System.out.println(DateFormat.getDateInstance(DateFormat.FULL,

new Locale("it", "IT")).format(date));// marted� 16 ottobre 2012

System.out.println(DateFormat.getDateInstance(DateFormat.FULL,

Locale.ITALIAN).format(date));// marted� 16 ottobre 2012

// This uses default locale US

System.out.println(DateFormat.getDateInstance(DateFormat.FULL).format(

date));// Tuesday, October 16, 2012

System.out.println(DateFormat.getDateInstance().format(date));// Oct 16,

// 2012

System.out.println(DateFormat.getDateInstance(DateFormat.SHORT).format(

date));// 10/16/12

System.out.println(DateFormat.getDateInstance(DateFormat.MEDIUM)

.format(date));// Oct 16, 2012

System.out.println(DateFormat.getDateInstance(DateFormat.LONG).format(

date));// October 16, 2012

// Formatting Dates Using SimpleDateFormat

System.out.println(new SimpleDateFormat("yy-MM-dd").format(date));// 12-10-16

System.out.println(new SimpleDateFormat("yy-MMM-dd").format(date));// 12-Oct-16

System.out.println(new SimpleDateFormat("yyyy-MM-dd").format(date));// 2012-10-16

// Parse Dates using DateFormat

Date date2 = DateFormat.getDateInstance(DateFormat.SHORT).parse(

"10/16/12");

System.out.println(date2);// Tue Oct 16 00:00:00 GMT+05:30 2012

// Creating Dates using SimpleDateFormat

Date date1 = new SimpleDateFormat("yy-MM-dd").parse("12-10-16");

System.out.println(date1);// Tue Oct 16 00:00:00 GMT+05:30 2012

// Print the country of locale

Locale defaultLocale = Locale.getDefault();

System.out.println(defaultLocale.getDisplayCountry());// United States

System.out.println(defaultLocale.getDisplayLanguage());// English
