Year until() Method in Java with Examples

Last Updated : 22 Jan, 2019

until() method of the Year class used to calculate the amount of time between two Year objects using TemporalUnit. The start and end points are this and the specified Year passed as a parameter. The result will be negative if the end is before the start. The calculation returns a whole number, representing the number of complete units between the two Year. This instance is immutable and unaffected by this method call. Syntax:

public long until(Temporal endExclusive, TemporalUnit unit)

Parameters: This method accepts two parameters endExclusive which is the end date, exclusive, which is converted to a Year and unit which is the unit to measure the amount. Return value: This method returns the amount of time between this Year and the end Year. Exception:This method throws following Exceptions:

DateTimeException – if the amount cannot be calculated, or the ending temporal cannot be converted to a Year.
UnsupportedTemporalTypeException – if the unit is not supported.
ArithmeticException – if numeric overflow occurs.

Below programs illustrate the until() method: Program 1:

Java

// Java program to demonstrate
// Year.until() method

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {
        // create Year objects
        Year y1 = Year.of(2018);
        Year y2 = Year.of(2015);

        // apply until the method of Year class
        long result
            = y2.until(y1,
                       ChronoUnit.YEARS);

        // print results
        System.out.println("Result in YEARS: "
                           + result);
    }
}

Output:

Result in YEARS: 3

Program 2:

Java

// Java program to demonstrate
// Year.until() method

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {
        // create Year objects
        Year y1 = Year.of(2018);
        Year y2 = Year.of(2200);

        // apply until the method of Year class
        long result
            = y1.until(y2,
                       ChronoUnit.DECADES);

        // print results
        System.out.println("Result in DECADES: "
                           + result);
    }
}
