Consider below codes of 3 java files:
1. //Super.java
2. package com.sampleproject.oca;
3.
4. public interface Super {
5. String name = "SUPER"; //Line n1
6. }
1. //Sub.java
2. package com.sampleproject.oca;
3.
4. public interface Sub extends Super { //Line n2
5.
6. }
1. //Test.java
2. package com.sampleproject.oca;
3.
4. public class Test {
5. public static void main(String[] args) {
6. Sub sub = null;
7. System.out.println(sub.name); //Line n3
8. }
9.
Which of the following statements is correct?
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?

1. public class Thought {
2. /*INSERT*/ {
3. System.out.println("All is well");
4. }
5. }
Which 3 options, if used to replace /*INSERT*/, will compile successfully and on execution will print "All is well" on to the console?
