List of minusYears() Examples

Examples of minusYears()

org.joda.time.DateTime.minusYears()
Returns a copy of this datetime minus the specified number of years.
The calculation will do its best to only change the year field retaining the same month of year. However, in certain circumstances, it may be necessary to alter smaller fields. For example, 2008-02-29 minus one year cannot result in 2007-02-29, so the day of month is adjusted to 2007-02-28.
The following three lines are identical in effect:
```
 DateTime subtracted = dt.minusYears(6); DateTime subtracted = dt.minus(Period.years(6)); DateTime subtracted = dt.withFieldAdded(DurationFieldType.years(), -6); 
```
This datetime instance is immutable and unaffected by this method call. @param years the amount of years to subtract, may be negative @return the new datetime minus the increased years @since 1.1
org.joda.time.LocalDate.minusYears()
Returns a copy of this date minus the specified number of years.
This LocalDate instance is immutable and unaffected by this method call.
The following three lines are identical in effect:
```
 LocalDate subtracted = dt.minusYears(6); LocalDate subtracted = dt.minus(Period.years(6)); LocalDate subtracted = dt.withFieldAdded(DurationFieldType.years(), -6); 
```
@param years the amount of years to subtract, may be negative @return the new LocalDate minus the increased years
org.threeten.bp.LocalDate.minusYears()
Returns a copy of this {@code LocalDate} with the specified period in years subtracted.
This method subtracts the specified amount from the years field in three steps:
1. Subtract the input years to the year field
2. Check if the resulting date would be invalid
3. Adjust the day-of-month to the last valid day if necessary
For example, 2008-02-29 (leap year) minus one year would result in the invalid date 2007-02-29 (standard year). Instead of returning an invalid result, the last valid day of the month, 2007-02-28, is selected instead.
This instance is immutable and unaffected by this method call. @param yearsToSubtract the years to subtract, may be negative @return a {@code LocalDate} based on this date with the years subtracted, not null @throws DateTimeException if the result exceeds the supported date range
org.threeten.bp.Year.minusYears()
Returns a copy of this year with the specified number of years subtracted.
This instance is immutable and unaffected by this method call. @param yearsToSubtract the years to subtract, may be negative @return a {@code Year} based on this year with the period subtracted, not null @throws DateTimeException if the result exceeds the supported year range
org.threeten.bp.YearMonth.minusYears()
Returns a copy of this year-month with the specified period in years subtracted.
This instance is immutable and unaffected by this method call. @param yearsToSubtract the years to subtract, may be negative @return a {@code YearMonth} based on this year-month with the years subtracted, not null @throws DateTimeException if the result exceeds the supported range
