Given code of Thought.java file:
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?
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?
Given the code fragment:
Given code of Test.java file:
1. package com.sampleproject.oca;
2.
3. interface Blogger {
4. default void blog() throws Exception {
5. System.out.println("GENERIC");
6. }
7. }
8.
9. class TravelBlogger implements Blogger {
10. public void blog() {
11. System.out.println("TRAVEL");
12. }
13. }
14.
15. public class Test {
16. public static void main(String[] args) {
17. Blogger blogger = new TravelBlogger(); //Line n1
18. ((TravelBlogger)blogger).blog(); //Line n2
19. }
20. }
What will be the result of compiling and executing Test class?
Below is the code of Test.java file:
1. package com.udayan.oca;
2.
3. import java.util.ArrayList;
4. import java.util.List;
5.
6. public class Test {
7. public static void main(String [] args) {
8. List
9.
10. list.add(27);
11. list.add(27);
12.
13. list.add(new Integer(27));
14. list.add(new Integer(27));
15.
16. System.out.println(list.get(0) == list.get(1));
17. System.out.println(list.get(2) == list.get(3));
18. }
19. }
What will be the result of compiling and executing Test class?
