The minus(long, unit) method of Year class is used to return a copy of this year after subtracting the specified amount of unit from this Year object.An exception is thrown, If the specified unit cannot be subtracted from Year. This instance is immutable and unaffected by this method call.
Syntax:
public Year minus(long amountToSubtract, TemporalUnit unit)
Parameters: This method accepts two parameters:
- amountToSubtract: This parameter represents the amount of the unit to subtract from the result.
- unit: This parameter represents the unit of the amount to subtract.
Return Value: This method returns a Year based on this year with the specified amount subtracted.
Exception: This method throws following Exceptions:
- DateTimeException – This exception is thrown if the subtraction cannot be made.
- UnsupportedTemporalTypeException – This exception is thrown if the unit is not supported.
- ArithmeticException – This exception is thrown if numeric overflow occurs.
Below programs illustrate the minus(long, unit) method:
Program 1:
// Java program to demonstrate// Year.minus(long, unit) method  import java.time.*;import java.time.temporal.*;  public class GFG {    public static void main(String[] args)    {        // create a Year object        Year year = Year.of(2019);          // print instance        System.out.println("Year :"                           + year);          // apply minus(long, unit) method        // subtracting 20 years        Year value            = year.minus(20, ChronoUnit.YEARS);          // print result        System.out.println("After subtraction year: "                           + value);    }} |
Output:
Year :2019 After subtraction year: 1999
Program 2:
// Java program to demonstrate// Year.minus(long, unit) method  import java.time.*;import java.time.temporal.*;  public class GFG {    public static void main(String[] args)    {        // create a Year object        Year year = Year.of(2022);          // print instance        System.out.println("Year :"                           + year);          // apply minus(long, unit) method        // subtracting 30 years        Year value            = year.minus(30, ChronoUnit.YEARS);          // print result        System.out.println("After subtraction year: "                           + value);    }} |
Output:
Year :2022 After subtraction year: 1992
