Examples


package com.logicbig.example.year;

import java.time.Year;
import java.time.temporal.ChronoField;
import java.time.temporal.Temporal;
import java.time.temporal.TemporalAdjuster;

public class WithExample {

    public static void main(String... args) {
        Year y = Year.of(1999);
        System.out.println(y);

        Year with = y.with(firstYearOfDecadeAdjuster);
        System.out.println(with);

    }

    private static final TemporalAdjuster firstYearOfDecadeAdjuster = new TemporalAdjuster() {
        @Override
        public Temporal adjustInto(Temporal temporal) {
            if (temporal.isSupported(ChronoField.YEAR)) {
                int i = temporal.get(ChronoField.YEAR);
                return Year.of((i / 10) * 10);
            }
            return null;
        }
    };
}

Output

1999
1990




package com.logicbig.example.year;

import java.time.Year;
import java.time.temporal.ChronoField;

public class WithExample2 {

    public static void main(String... args) {
        Year y = Year.of(2011);
        System.out.println(y);

        for (ChronoField chronoField : ChronoField.values()) {
            if (y.isSupported(chronoField)) {
                Year y2 = y.with(chronoField, 1);
                System.out.printf("%15s => %s%n", chronoField.name(), y2);
            }
        }
    }
}

Output

2011
    YEAR_OF_ERA => 1
           YEAR => 1
            ERA => 2011
