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?

Given:

Consider below codes of 2 java files:

1. //Flyable.java

2. package com.sampleproject.oca;

3.  

4. public interface Flyable {

5.     static int horizontalDegree() { //Line n1

6.         return 20;

7.     }

8.  

9.     default void fly() {

10.         System.out.println("Flying at " + horizontalDegree() + " degrees."); //Line n2

11.     }

12.  

13.     void land();

14. }

1. //Aeroplane.java

2. package com.sampleproject.oca;

3.  

4. public class Aeroplane implements Flyable {

5.     public void land() {

6.         System.out.println("Landing at " + -Flyable.horizontalDegree() + " degrees."); //Line n3

7.     }

8.  

9.     public static void main(String[] args) {

10.         new Aeroplane().fly();

11.         new Aeroplane().land();

12.     }

13. }

What will be the result of compiling and executing Aeroplane class?
