you can use the Calendar class to do so   SimpleDateFormat format   new SimpleDateFormat  yyyy MM dd HH mm    Calendar cal   Calendar getInstance    cal add Calendar MONTH  -1   System out println format format cal getTime        This prints   2012 09 10 11 01 for actual date 2012 10 10 11 01

You need to be aware that month is zero based so when you do the getMonth you will need to add 1  In the example below we have to add 1 to Januaray as 1 and not 0       Calendar c   Calendar getInstance        c set 2011  2  1       c add Calendar MONTH  -1       int month   c get Calendar MONTH    1      assertEquals 1  month

Use Joda Time Library  It is very easy to handle date  time  calender and locale with it and it will be integrated to java in version 8   DateTime minusMonths method would help you get previous month   DateTime month   new DateTime   minusMonths  1

Your solution is here but instead of addition you need to use subtraction  c add Calendar MONTH  -1     Then you can call getter on the Calendar to acquire proper fields  int month   c get Calendar MONTH    1     beware of month indexing from zero int year    c get Calendar YEAR

The simplest  amp  least error prone approach is    Use Calendar s roll   method  Like this       c roll Calendar MONTH  false     the roll method takes a boolean  which basically means roll the month up true  or down false
