Date Class error in java

I have Date today=new Date(); which returns the current date.. but when i try to display date,month,year separately with the help of

DateFormat mmFormat=new SimpleDateFormat("MM"); 
System.out.println(mmFormat.format(today.getMonth()));
DateFormat yyFormat=new SimpleDateFormat("yyyy"); 
System.out.println(yyFormat.format(today.getYear()));

it prints month as 01 and year as 1970

how to resolve this.?

Better in this way

    Date date=new Date(); // your date
    Calendar cal = Calendar.getInstance();
    cal.setTime(date);
    int year = cal.get(Calendar.YEAR);
    int month = cal.get(Calendar.MONTH);
    int day = cal.get(Calendar.DAY_OF_MONTH);
    System.out.println(year+"\n"+month);

That is because all these methods are deprecated. Use 

 Calendar myCalendar = GregorianCalendar.getInstance();
 myCalendar.get(Calendar.MONTH);
 myCalendar.get(Calendar.YEAR);
 myCalendar.get(Calendar.DAY_OF_MONTH);

You would need to use Calendar. Have a look at the java docs.

You can do it like this -

Calendar cal = Calendar.getInstance();

System.out.println(cal.get(Calendar.DAY_OF_MONTH));
System.out.println(cal.get(Calendar.MONTH)); // month in the Calendar class begins from 0
System.out.println(cal.get(Calendar.YEAR));
System.out.println(cal.get(Calendar.HOUR_OF_DAY));
System.out.println(cal.get(Calendar.MINUTE));
System.out.println(cal.get(Calendar.SECOND));

This would help you to avoid creating multiple DateFormat objects. Also in case you want to use another date instead of today's date the you can just pass the date to the cal.setTime() method.

today.getMonth() and today.getYear() returns an int which is interpreted as an UNIX timestamp . The value is 1 and 113 , which corresponds to approximately January 1, 1970, 00:00:01 GMT and January 1, 1970, 00:01:53 GMT represented by this Date object. To get the desired result , you need to pass the Date object :

System.out.println(mmFormat.format(today));

mmFormat.format(today.getMonth())

You're passing an integer – the month of the date – to a date format method.

The format method interprets that integer as a UNIX timestamp – a number of seconds since 1970.

You need to pass the date itself to the formatter.

Just use the Date today as the input argument

System.out.println(mmFormat.format(today));

and

System.out.println(yyFormat.format(today));

Pass the entire date to SimpleDateFormat. The format string "MM" or "yyyy" will cause it to just extract the part of the date you want.
