Method:

public LocalDate withDayOfYear(int dayOfYear)

This method returns a new copy of this local date, with day-of-year field replaced with the provided 'dayOfYear' value.

If the provided dayOfYear is invalid, an exception is thrown.


Examples


package com.logicbig.example.localdate;

import java.time.LocalDate;

public class WithDayOfYearExample {

    public static void main (String... args) {
        LocalDate d = LocalDate.of(2016, 2, 1);

        LocalDate d1 = d.withDayOfYear(1);
        System.out.println(d1);

        LocalDate d2 = d.withDayOfYear(100);
        System.out.println(d2);


    }
}

Output

2016-01-01
2016-04-09




Invalid value of year will throw DateTimeException. 

package com.logicbig.example.localdate;

import java.time.LocalDate;

public class WithDayOfYearExample2 {

    public static void main (String... args) {
        LocalDate d = LocalDate.of(2016, 2, 10);
        LocalDate d1 = d.withDayOfYear(367);
        System.out.println(d1);
    }
}
