Below programs illustrate the plus(long, unit) method: Program 1:

Java

// Java program to demonstrate
// Year.plus(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 plus(long, unit) method
        // adding 30 years
        Year value
            = year.plus(30, ChronoUnit.YEARS);

        // print result
        System.out.println("After addition year: "
                           + value);
    }
}

Output:

Year :2019
After addition year: 2049

Program 2:

Java

// Java program to demonstrate
// Year.plus(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 plus(long, unit) method
        // adding 50 years
        Year value
            = year.plus(50, ChronoUnit.YEARS);

        // print result
        System.out.println("After addition year: "
                           + value);
    }
}
