Consider below code of Test.java file:

1. package com.sampleproject.oca; 

2.  

3. public class Test {

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

5.         /*INSERT*/ x = 7, y = 200;

6.         System.out.println(String.valueOf(x + y).length());

7.     }

8. }

Which of the following options, if used to replace /*INSERT*/, will compile successfully and on execution will print 3 on to the console?

Select 3 options.

Given code of Test.java file:

1. package com.sampleproject.oca;

2.  

3. public class Test {

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

5.         try { //outer

6.             try { //inner

7.                 System.out.println(1/0);

8.             } catch(ArithmeticException e) {

9.                 System.out.println("INNER");

10.             } finally {

11.                 System.out.println("FINALLY 1");

12.             }

13.         } catch(ArithmeticException e) {

14.             System.out.println("OUTER");

15.         } finally {

16.             System.out.println("FINALLY 2");

17.         }

18.     }

19. }

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

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?

Consider below code of Test.java file:

1. package com.sampleproject.oca;

2.  

3. interface Perishable1 {

4.     default int maxDays() {

5.         return 1;

6.     }

7. }

8.  

9. interface Perishable2 extends Perishable1 {

10.     default int maxDays() {

11.         return 2;

12.     }

13. }

14.  

15. class Milk implements Perishable2, Perishable1 {}

16.  

17. public class Test {

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

19.         Perishable1 obj = new Milk();

20.         System.out.println(obj.maxDays());

21.     }

22. }

Which of the following statements is correct?
