java.util.Date - Deleting three months from a date?

Question

I have a date of type java.util.Date

I want to subtract three months from it.

Not finding a lot of joy in the API.

Answer 1

public static Date getDateMonthsAgo(int numOfMonthsAgo)
{
    Calendar c = Calendar.getInstance(); 
    c.setTime(new Date()); 
    c.add(Calendar.MONTH, -1 * numOfMonthsAgo);
    return c.getTime();
}

will return the date X months in the past. Similarily, here's a function that returns the date X days in the past.

public static Date getDateDaysAgo(int numOfDaysAgo)
{
    Calendar c = Calendar.getInstance(); 
    c.setTime(new Date()); 
    c.add(Calendar.DAY_OF_YEAR, -1 * numOfDaysAgo);
    return c.getTime();
}
