Consider below code:
1. //Test.java
2. package com.udayan.oca;
3.
4. import java.time.LocalDate;
5.
6. public class Test {
7. public static void main(String [] args) {
8. LocalDate joiningDate = LocalDate.parse("2006-03-16");
9. System.out.println(joiningDate.withDayOfYear(29));
10. }
11. }
What will be the result of compiling and executing Test class?
