Which two statements are true? (Choose two.)
Given:
Given the code fragment:
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?
Consider below code:
1. //Test.java
2. package com.udayan.oca;
3.
4. public class Test {
5. public static void main(String[] args) {
6. StringBuilder sb = new StringBuilder(100);
7. System.out.println(sb.length() + ":" + sb.toString().length());
8. }
9. }
What will be the result of compiling and executing Test class?
